Section 1 Introduction and Specifications

Scope of Manual

This instruction manual is a supplement to the DLC3100 and DLC3100 SIS Quick Start Guide (D104214X012) that ships with every digital level controller. This instruction manual includes specifications, operating, and maintenance information for FIELDVUE DLC3100 and DLC3100 SIS digital level controllers.

Notes

The DLC3100 SIS is identified by a label affixed to the terminal box cover.

Unless otherwise noted, the information in this document applies to both DLC3100 and DLC3100 SIS. However, for simplicity, the DLC3100 model name will be used throughout.

This instruction manual supports the 475 Field Communicator with device description revision 1, used with DLC3100 instruments with firmware revision 1.0.9. You can obtain information about the process, instrument, or sensor using the Field Communicator. Contact your Emerson sales office

to obtain the appropriate software.

Do not install, operate, or maintain a DLC3100 digital level controller without being fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is

important to carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you have any questions regarding these instructions, contact your Emerson sales office before proceeding.

Installation, Mounting and Electrical Connections, and Initial Configuration and Calibration using the Local User Interface

Refer to the DLC3100 and DLC3100 SIS Quick Start Guide (D104214X012) for installation and connection information, as well as initial configuration and calibration using the local user interface. If a copy of this quick start guide is needed contact your Emerson sales office or visit Fisher.com.

Conventions Used

This manual describes using the Field Communicator to configure and calibrate the digital level controller.

Procedures that require the use of the Field Communicator have the text path and the sequence of numeric keys required to display the desired Field Communicator menu.

Description

DLC3100 Digital Level Controller

DLC3100 digital level controllers (figure 2) are used with level sensors to measure liquid level, the level of interface between two liquids, or liquid density. Changes in level or density exert a buoyant force on a displacer, which rotates the torque tube shaft (see figure 3). This rotary motion is applied to the digital level controller, transformed to an electrical signal and digitized. The digital signal is compensated and processed per user configuration requirements, and converted back to a 4-20 mA analog electrical signal. See the block diagram in figure 4.

Several operations with the DLC3100 can be performed using the Field Communicator. The digital level controller can be configured, calibrated, or tested. Using the HART protocol, information from the field can be integrated into control systems or be received on a single loop basis.

DLC3100 digital level controllers are designed to directly replace standard pneumatic and electro-pneumatic level transmitters. DLC3100 digital level controllers mount on a wide variety of caged and cageless 249 level sensors. They can also be mounted on other manufacturers’ displacer type level sensors with designed mounting kits.

DLC3100 Digital Level Controller

July 2019

CAUTION

There are many magnets used in the DLC3100 (lever assembly, push button, coupling handle). Care must be taken to avoid having a high powered magnet in close proximity. This could cause permanent damage to the DLC3100. Potential sources of damaging equipment include, but are not limited to: transformers, DC motors, stacking magnet assemblies.

General Guidelines for use of High Power Magnets:

Use of high power magnets in close proximity to any instrument which is operating a process should be avoided. Regardless of the instrument model, high power magnets can affect its functionality.

249 Caged Sensors

249, 249B, 249BF, 249C, 249K and 249L sensors side-mount on the vessel with the displacer mounted inside a cage outside the vessel.

249 Cageless Sensors

249BP, 249CP and 249P sensors top-mount on the vessel with the displacer hanging down into the vessel.

249VS sensor side-mounts on the vessel with the displacer hanging out into the vessel.

249W wafer-style sensor mounts on top of a vessel or on a customer-supplied cages.

Test Connections

WARNING

Personal injury or property damage caused by fire or explosion may occur if this connection is attempted in an area which contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of the terminal box cap before proceeding.

) that shipped with your

Test connections inside the terminal box can be used to measure loop current across an internal 1 ohm resistor.

1. Remove the terminal box cap.

2. Adjust the test meter to measure mV.

3. Connect the positive lead of the test meter to the + connection and the negative lead to the TEST connection inside the terminal box.

4. Measure Loop current as mV = mA. For example, if the meter measures 12.5 mV, it means the loop current is

12.5 mA.

5. Remove test leads and replace the terminal box cover.

Alarm Conditions

Each digital level controller continuously monitors its own performance during normal operation. This automatic diagnostic routine is a timed series of checks repeated continuously. If diagnostics detect a failure in the electronics, the instrument drives its output to trip alarm current either below 3.6 mA or above 21 mA, depending on the position (High/Low) of the alarm switch.

An alarm condition occurs when the self-diagnostics detect an error that would render the process variable measurement inaccurate, incorrect, or undefined, or a user defined threshold is violated. At this point the analog output of the unit is driven to a defined level either above or below the nominal 4-20 mA range, based on the position

of the alarm switch. The factory default Alarm Switch setting is High.

Refer to table 9 for alerts that will trigger the Trip Alarm Current when enabled.

Note

The DLC3100 must be put out of service during Loop Test. Place the loop into manual operation before putting device out of service as the DLC3100 output may not be valid.

When the DLC3100 is out of service, it is locked for exclusive access by the Primary/Secondary master that put it out of service. If the instrument reports Locked by HART or Access Restricted when you attempt to configure it, and a master of the original priority is not available, use Force Mode on the Local User Interface menu to force the instrument mode to In Service. You will then be able to take it out of service with your own master to make changes.

Loop Test can be used to verify the controller output, the integrity of the loop, and the operations of any recorders or similar devices installed in the loop. To initiate a loop test, perform the following procedure:

1. Connect a reference meter to the controller. To do so, either connect the meter to the test connections inside the terminal box (see Test Connections procedure) or connect the meter in the loop as shown in figure 8.

2. Access Loop Test via Service Tools > Maintenance > Tests > Loop Test (3-4-2-2).

3. Select OK after you set the control loop to manual. The Field Communicator displays the loop test menu.

4. Put the instrument to “Not in Service” and select analog output level: 4mA, 20mA or Other to manually input a value between 4 and 20 milliamps.

5. Check the reference meter to verify that it reads the value that is commanded. If the readings do not match, either the controller requires an output trim, or the meter is malfunctioning.

After completing the test procedure, the display returns to the loop test screen and allows you to choose another output value or end the test and put instrument back in service.

July 2019

The DLC3100 will continue to regulate the current output based on lever assembly position. The output can be at failed current value (determine by alarm switch on the Main Electronics Board) depending on the device alerts/status. This current output shall not be treated as actual level/interface measurement as the device is “Not In Service”.

CAUTION

The control loop must be in manual before putting DLC3100 to Not In Service.

Note

When configuring the DLC3100 using the DD, the access of DLC3100 via Local User Interface will be locked.

If a DLC3100 digital level controller ships from factory mounted on a 249 sensor, initial setup and calibration may not be necessary. The factory enters the sensor data, couples the instrument to the sensor, and calibrates the instrument and sensor combination.

DLC3100 Digital Level Controller

July 2019

Instruction Manual

D104213X012

Note

If the digital level controller mounted on the sensor is received with the displacer blocked, or if the displacer is not connected, the instrument will be coupled to the torque tube assembly and the lever assembly unlocked. To place the unit in service, if the displacer is blocked, remove the rod and block at each end of the displacer and check the instrument calibration. (If the “factory cal” option was ordered, the instrument will be pre-compensated to the process conditions provided on the requisition, and may not appear to be calibrated if checked against room temperature with 0% and 100% water level inputs). If the displacer is not connected, hang the displacer on the torque tube.

If the digital level controller mounted on the torque tube arm and the displacer is not blocked when received (such as in skid mounted systems), the instrument will not be coupled to the torque tube assembly, and the lever assembly will be locked. To place the unit in service, couple the instrument to the sensor and unlock the lever assembly.

When the 249 assembly is properly connected and coupled to the digital level controller, establish the zero process condition and perform the Trim Zero procedure. The torque tube rate should not need to be recalibrated.

To review the configuration data entered by the factory, connect the instrument to a 24 VDC power supply as shown in figure 8. Connect the AMS Device Manager/Field Communicator to the instrument and turn it on. Go to Configure and review the data under Manual Setup and Alert Setup. If application data has been changed since the instrument was factory-configured, refer to the Manual Setup section for instructions on modifying configuration data.

Configuration Advice

Force Mode

Local User Interface Menu > Force Mode

When the DLC3100 is out of service, it is locked for exclusive access by the Primary/Secondary master that put it out of service. The same master must be used to put the instrument back in service; another master will not be able to change anything on the device and the LCD will return a “Locked by HART” message, unless you run Force Mode.

Select Force Mode to force the instrument mode to In Service if the original master is not available.

Note

Make sure no outstanding tasks are on-going in the device, including configuration and calibration, before forcing the DLC3100 In Service

Write Protection

To setup and calibrate the instrument, write protection must be set to disable.

Level Offset

Level Offset is the value DLC3100 reports when the process level is at the bottom of the displacer. Adding a level offset permits the process variable value in engineering units to be reported with respect to a reference point other than the bottom of the displacer. Examples include: bottom of the process vessel, the process set point, or sea level. Set Level Offset is only available in Level or Interface measurement mode. Follow the prompts on the Field Communicator to enter the offset value (2-3-2-1-6).

Level Offset will affect URV/LRV, PV Hi/Lo, PV HiHi/LoLo alerts. Changing PV alert points assumes you have already considered the affect of Level Offset on the alert points. This parameter should be cleared to zero before running Device Setup.

Initial Setup

Initial Setup consists of the following:

D Device Setup

D PV Setup

D Process Setup

All three setup procedures must be completed when configuring the DLC3100 in order for the device to function properly.

Initial Setup directs you through initialization of configuration data needed for proper operation. When the instrument comes out of the box, the default dimensions are set for the most common Fisher 249 construction. If any data is unknown, it is generally safe to accept the defaults. The mounting position - left or right of displacer - is important for correct interpretation of positive motion. Use Manual Setup to locate and modify individual parameters when they need to be changed. Refer to the Initial Setup section below for DLC3100 configuration.

Notes

The DLC3100 has to be “Not In Service” when carrying out Initial Setup. Place the loop into manual operation before putting device out of service as the output will not be valid.

Guided setup is available to aid initial setup. Follow the prompts to enter information required by the setup. Most of the information is available from the sensor nameplate.

Device Setup

AMS Configure > Guided Setup > Device Setup Field Communicator Configure > Guided Setup > Device Setup (2-2-1)

Input the required information as follows:

D Displacer Information (Length, Weight and Volume)

D Driver Rod Length (refer to table 11 and figure 9)

D Mounting Position (Left or Right of Displacer)

D 249 Sensor Model

D Torque Tube Material and wall thickness

The Driver Rod (moment arm) is the effective length of the driver rod length, and depends upon the sensor type. For a 249 sensor, refer to table 11 to determine driver rod length.

Once Device Setup is completed, configure the application settings using the PV Setup procedures.

Table 12. Application Information

Measurement Application Description

The default process variable units are set to the same units chosen for displacer length. When level

Level, Interface

Density

offset is changed, range values will be initialized based on level offset and displacer length. The default upper range value is set to equal to displacer length and the default lower range value is set to zero when the level offset is 0.

The default process variable units are set to “SGU” (Specific Gravity Units). The default upper range value is set to “1.0” and the default lower range value is set to ”0.1”.

When a DLC3100 with analog output is set for direct action the loop current will increase as the fluid level increases. Upper Range Value is the process variable values at 20 mA and Lower Range Value is the process variable values at 4 mA.

Choosing Reverse action will swap the default values of the upper and lower range values. The loop current will decrease as the fluid level increases. Upper Range Value is the process variable values at 4 mA and Lower Range Value is the process variable values at 20 mA.

Once PV Setup is completed configure the process information using the Process Setup procedures.

Two-Points Calibration is usually the most accurate method for calibrating the sensor. It uses independent observations of two valid process conditions, together with the hardware dimensional data and specific gravity information, to compute the effective torque rate of the sensor. The two data points can be separated by any span between a minimum of 5% to 100%, as long as they remain on the displacer. Within this range, the calibration accuracy will generally increase as the data point separation gets larger. Accuracy is also improved by running the procedure at process temperature, as the temperature effect on torque rate will be captured. (It is possible to use theoretical data to pre-compensate the measured torque rate for a target process condition when the calibration must be run at ambient conditions).

1 REFER TO TABLE 17 FOR MAXIMUM LOAD ALLOWED ON TORQUE TUBE.

Weight Calibration may be used on the bench or with a calibration jig that can apply a mechanical force to the driver rod to simulate displacer buoyancy changes. It allows the instrument and sensor to be calibrated using equivalent weights or force inputs instead of using the actual displacer buoyancy changes. If the displacer information has been entered prior to beginning the procedure, the instrument will be able to compute reasonable weight value suggestions for the calibration. The weight values suggested during the weight calibration aim to achieve maximum torque tube rotation for better accuracy. It does not necessary mean the weight at 0% or 100%. The only preliminary data essential for the correct calibration of the torque rate is the length of the driver rod being used for the calibration. Weight equivalent to the net displacer weight at two valid process conditions must be available. The sensor must have been sized properly for the expected service, so that the chosen process conditions are in the free motion linear range of the sensor.

Accuracy Considerations

Effect of Proportional Band

If a DLC3100 with level sensor is operating at low Proportional Band [PB = 100% times (full span torque tube rotation) / (4.4 degrees)], there will be a degradation factor of about (100%)/(PB%) on the device accuracy specifications.

Note

This formula is most correct for linearity errors that are relatively steep‐sided. If the linearity error curve shape is simple with relatively gradual slope, the net effect of reducing span may be less. Instruments such as the DLC3100, that use a compensation technique to reduce the residual mechanical or electrical non‐linearity, will generally have a complex shape for the net‐error curve.

If this is too much degradation, an improvement of 2.0 can be obtained by using a thin‐wall torque tube. Additional gain can be achieved by increasing the displacer diameter. Available clearance inside the cage, and the need to keep the net displacer weight at the highest and lowest process conditions within the usable range of the torque tube/driver rod combination, place practical limits on how much the sizing can be adjusted.

With an overweight displacer, the calibration process becomes more difficult as the zero buoyancy condition will occur with the linkage driven hard into a travel stop. In interface measurement application, it is recommended to calibrate with actual process fluids (upper and lower fluids), or set the application to level and use water to calibrate the DLC3100.

Density Variations in Interface Applications

A high sensitivity to errors in the knowledge of fluid density can develop in some interface applications.

For example: Suppose the whole input span is represented by an effective change in SG of 0.18. Then a change in the actual SG of the upper fluid from 0.8 to 0.81 could cause a measurement error of 5.6% of span at the lowest interface level. The sensitivity to the knowledge of a fluid density is maximum at the process condition where that fluid covers all the displacer, zero at the opposite extreme process condition, and varies linearly between those points.

If the fluid density changes are batch‐related or very gradual, it may be practical to keep track of the SG of the fluid and periodically reconfigure the DLC3100 density setting to match the actual process condition. Frequent automatic updates to this variable are not advisable as the NVM location where it is stored has a write limit. If changes are only a function of temperature, the characteristic of the fluid can be loaded once in the density table, and an RTD connected to measure the process temperature and drive the temperature compensation table. If temperature is not the driving influence, the best that can be done is to calibrate for the widest potential differential SG. This will keep the variations as small a percentage of calibrated span as possible. Then calculate an alarm threshold that will prevent vessel over‐ or under‐flow at the worst-case error.

Instruction Manual

D104213X012

Extreme Process Temperatures

For applications that will run at extreme temperatures, the effect of process temperature on the torque tube must be considered. Best results are obtained by running the torque tube calibration at actual process temperature. However, the decrease in spring rate with temperature can be simulated at room temperature by increasing the load on the torque tube during room‐temperature calibration. This will produce the same deflection that would occur at actual process conditions. This compensation is theoretical and not perfect, but is still an improvement over ambient calibration with no attempt at compensation.

Note

For additional information, refer to the Simulation of Process Conditions for Calibration of Fisher Level Controllers and Transmitters instruction manual supplement (D103066X012

), available at Fisher.com.

Temperature Compensation

AMS Configure > Manual Setup > Process Field Communicator Configure > Manual Setup > Process (2-3-4)

If the process temperature departs significantly from calibration temperature, temperature compensation can be enabled. By selecting Process Temperature Input to either RTD or Manual, the temperature compensation will be enabled. DLC3100 digital level controller will use the correct fluid density from the default fluid table (depending on fluid type selected, see table 18 for example) or custom table (user input) based on the actual process temperature. Custom Table must have ascending temperature inputs.

You can also correct the temperature effect by applying a correction factor to the torque tube rate. Interpolate the correction factor from the material‐specific tables of theoretical normalized modulus of rigidity versus temperature, as described in Simulation of Process Conditions for Calibration of Fisher Level Controllers and Transmitters (D103066X012

). Multiply the measured torque tube rate (editable in Configure > Calibration > Trim Current Calibration > Torque Tube Gain) by the correction factor and enter the new value. This approach allows a better approximation of the actual torque tube behavior at process conditions when calibration cannot be carried out at process temperature.

Section 6 Maintenance and Troubleshooting

The DLC3100 digital level controller features a modular design for easy maintenance. If there is a malfunction, check for an external cause before performing the diagnostics describe in this section.

Sensor parts are subject to normal wear and must be inspected and replaced as necessary. For sensor maintenance information, refer to appropriate sensor instruction manual.

WARNING

To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any maintenance operations.

Personal injury or property damage due to sudden release of pressure, contact with hazardous fluid, fire, or explosion can be caused by puncturing, heating, or repairing a displacer that is retaining process pressure or fluid. This danger may not be readily apparent when disassembling the sensor or removing the displacer. Before disassembling the sensor or removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.

Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

CAUTION

When replacing components, use only components specified by the factory. Always use proper component replacement techniques, as presented in this manual. Improper techniques or component selection may invalidate the approvals and the product specifications, as indicated in table 1. It may also impair operations and the intended function of the device.

Alert Messages

In addition to the level measurement and output current, the LCD displays abbreviated alert messages for troubleshooting the digital level controller. To check for alert messages, push the left button when the LCD is in Home screen with “ALERTS” shown at the bottom of the LCD. A description of each alert message is shown in table 19.

Make sure the Field Communicator has the correct Device Description to communicate with the DLC3100 digital level controller.

Check resistance between the power supply and the Field Communicator connection. The net resistance in the loop must be between 230 and 600ohms for HART communication. Check for adequate voltage to the digital level controller. Refer to figure 10 for requirements. Some models of battery operated field calibrators do not have sufficient compliance voltage to operate a DLC3100 over the entire output current range. Check for excessive capacitance in the field wiring (Isolate the instrument from field wiring and try to communicate locally).

The terminal box may have developed a high internal resistance. Try replacing the terminal box electronics board.

Check for open circuit. Check for proper polarity at the +/- terminals. Check for adequate voltage to the digital level controller.

Check resistance between Loop Power “+” and “T” terminals of terminal box. If greater than 1.1 ohm, the terminal sense resistor may be damaged. Replace the terminal box electronics.

Check LCD for alert messages to isolate failures. For DLC3100 SIS, check if the digital level controller is locked in safety and requires a manual reset. Check PV against the PV HiHi and PV LoLo alarm threshold and deadband setting, if these alarms are enabled.

Check the PV against the upper and lower range values. Check actual process condition and calibration adjustments.

Connect the Field Communicator and run a Loop Test. If the forced output does not track the commands, replace the Main Electronics Board.

Check torque tube rate change versus temperature per figure 6. Use appropriate material for process temperature. Pre-compensate the calibration for target process condition.

Connect the Field Communication and check instrument temperature. If instrument temperature value is extreme, replace the whole DLC3100 digital level controller.

Connect the Field Communicator and run Loop Test. Leave instrument in fixed current mode at 12 mA command and observe analog output variation with ambient temperature. If drift exceeds specifications, replace the main electronics board.

Connect the Field Communicator and check stored Specific Gravity values against independent measurement of process density. If process SG has changed from calibration values, correct the SG in configuration to match the process.

Removing the DLC3100 from the Sensor

Because the DLC3100 digital level controller has a modular design, most of the service and maintenance to the digital level controller can be done without removing it from the sensor. However, if it is necessary to replace sensor to instrument mating parts or parts in the transducer housing, or to perform bench maintenance, perform the following procedures to remove the digital level controller from the sensor.

WARNING

On an explosion proof instrument, remove the electrical power before removing the instrument covers in a hazardous area. Personal injury or property damage may result from fire and explosion if power is applied to the instrument with the covers removed.

Note

If the access handle will not slide, the sensor linkage is most likely in an extreme position. When the lever assembly is at a hard stop inside the housing, the locking pin on the access door may not be able to engage the mating slot in the lever assembly. This condition can occur if the displacer has been removed, if the sensor is lying on its side, or if the instrument had been coupled to the sensor while the displacer was not connected. To correct this condition, manipulate the sensor linkage to bring the lever assembly to within approximately 4 degrees of the neutral position before attempting to slide the handle. A probe inserted through the top vent of the 249 head may be required to deflect the driver rod to a position where the lever assembly is free.

Appendix A Principle of Operation

HART Communication

The HART (Highway Addressable Remote Transducer) protocol gives field devices the capability of communicating instrument and process data digitally. This digital communication occurs over the same two‐wire loop that provides the 4-20 mA process control signal, without disrupting the process signal. In this way, the analog process signal, with its faster update rate, can be used for control. At the same time, the HART protocol allows access to digital diagnostic, maintenance, and additional process data. The protocol provides total system integration via a host device.

The HART protocol uses the frequency shift keying (FSK) technique based on the Bell 202 communication standard. By superimposing a frequency signal over the 4-20 mA current, digital communication is attained. Two individual frequencies of 1200 and 2200 Hz are superimposed as a sinewave over the 4-20 mA current loop. These frequencies represent the digits 1 and 0 (see figure 21). The average value of this sinewave is zero, therefore no DC value is added to the 4-20 mA signal. Thus, true simultaneous communication is achieved without interrupting the process signal.

ANALOG SIGNAL

The HART protocol allows the capability of multidropping, networking several devices to a single communications line. This process is well suited for monitoring remote applications such as pipelines, custody transfer sites, and tank farms.

Multidrop Communication

“Multidropping” refers to the connection of several digital level controllers or transmitters to a single communications transmission line. Communication between the host and the field instruments takes place digitally with the analog output of the instruments deactivated. With the HART communications protocol, up to 15 field instruments can be connected on a single twisted pair of wires or over leased phone lines. Multidrop installations are not recommended where intrinsic safety is a requirement.

The application of a multidrop installation requires consideration of the update rate necessary from each instrument, the combination of instrument models, and the length of the transmission line. Communication with the field instruments can be accomplished with commercially available Bell 202 modems and a host implementing the HART protocol. Each instrument is identified by a unique address (1-15) and responds to the commands defined in the HART protocol.

POWER SUPPLY

LOAD

The Field Communicator can test, configure, and format a multidropped DLC3100 digital level controller in the same way as in a standard point‐to‐point installation, provided that it has been configured to scan for multiple polling addresses.

Note

DLC3100 digital level controllers are set to address 0 at the factory, allowing them to operate in the standard point‐to‐point manner with a 4-20 mA output signal. To activate multidrop communication, the address must be changed to a number between 1 and 15. This change deactivates the 4-20 mA analog output, sending it to 4 mA. The failure mode current also is disabled.

Digital Level Controller Operation

The DLC3100 digital level controller is a loop‐powered instrument that measure changes in liquid level, level of an interface between two liquids, or density of a liquid. Changes in the buoyancy of a displacer suspended in a vessel vary the load on a torque tube. The displacer and torque tube assembly constitute the primary mechanical sensor. The angular deflection of the torque tube is measured by the instrument transducer, which consists of a magnet system moving over a Hall effect device. A liquid crystal display (LCD) meter can display the analog output or process variable (level, interface level, or density) in units or percent range.

The instrument uses a microcontroller and associated electronic circuitry to measure the process variable, provide a current output, drive the LCD meter, and provide HART communications capability. Figure 23 shows the digital level controller assembly. Figure 24 is a block diagram of the main components in the instrument electronics; the LCD meter, the processor module, the transducer board, and the terminal board. The processor module contains the microprocessor, the analog‐to‐digital (A/D) converters, loop interface, signal conditioning, the digital‐to‐analog (D/A) output, power supply and interfaces to other boards.

DLC3100 Digital Level Controller

July 2019

A level, density, or interface level change in the measured fluid causes a change in the displacer position (figure 25). This change is transferred to the torque tube assembly. As the measured fluid changes, the torque tube assembly rotates up to 4.4 degrees for a 249 sensor, varying the digital level controller output between 4 and 20 mA.

Figure 25. Typical Sensor Operation

TORQUE TUBE

DISPLACER

W1389‐1

249 SENSOR (SIDE VIEW)

The rotary motion of the torque tube is transferred to the digital level controller lever assembly. The rotary motion moves a magnet attached to the lever assembly, changing the magnetic field that is sensed by the Hall effect sensor. The sensor converts the magnetic field signal to an electronic signal.

The microcontroller accepts the electronic signal, which is ambient‐temperature‐compensated and linearized. The microcontroller can also actively compensate for changes in liquid specific gravity due to changes in process temperature based on an input via HART protocol or via an optional RTD, if it is connected. The D/A output circuit accepts the microcontroller output and provides a 4 to 20 mA current output signal.

During normal operation, when the input is between the lower and upper range values, the digital level controller output signal ranges between 4 and 20 mA and is proportional to the input. See figure 26. If the input should exceed the lower and upper range values, the output will continue to be proportional to the input until the output reaches either 3.8 or 20.5 mA. At this time the output is considered saturated and will remain at this value until the input returns to the normal operating range. However, should an alarm occur, the output is driven to either > 21 mA or < 3.6 mA, depending on the Alarm High/Low switch setting.
