Fisherr FIELDVUEt DLC3010 Digital Level

Controller

The FIELDVUE DLC3010 digital level controller is used with level sensors to measure liquid level, the level of the interface between two liquids, or liquid specific gravity (density). Changes in level or specific gravity exert a buoyant force on a displacer, which rotates a torque tube shaft. The digital level controller converts this rotational motion to an electronic signal.

The DLC3010 is a communicating, microprocessor-based instrument that can be configured to sense the level, interface level, or density of liquids. In addition to the normal function of providing a 4 to 20 milliampere current signal, the DLC3010, using HARTR communications protocol, gives easy access to information critical to process operation. You can obtain information about the process, instrument, or sensor using the 475 or 375 Field Communicator. The DLC3010 can be used in analog or HART digital signaling mode with the Emerson Process Management DeltaVt system.

The connection for HART communication may be made at any point in the field wiring that meets the HART impedance requirements. Configuration, calibration, diagnostics, parameter review, signal monitoring and alert monitoring are all available

W7977-1

through the HART protocol. Information from the field can be integrated into control systems or be received on a single loop basis.

The DLC3010 digital level controller is designed to directly replace standard pneumatic and electronic level transmitters. It mounts on a wide variety of Fisher 249 caged and cageless level sensors.

DLC3010 Digital Level Controller Specifications

Available Configurations

DLC3010 Digital Level Controller:

Mounts on caged and cageless 249 sensors. See tables 4 and 5 and sensor description.

Function: Transmitter

Communications Protocol: HART

Input Signal

Level, Interface, or Density: Rotary motion of torque tube shaft proportional to changes in liquid level, interface level, or density that change the buoyancy of a displacer.

Process Temperature: Interface for 2- or 3-wire 100 ohm platinum RTD for sensing process temperature, or optional user-entered target

temperature to permit compensating for changes in specific gravity

Output Signal

Analog: 4 to 20 milliamperes DC (J direct action—increasing level, interface, or density increases output; or J reverse action—increasing level, interface, or density decreases output)

High saturation: 20.5 mA

Low saturation: 3.8 mA

High alarm: 22.5 mA

Low Alarm: 3.7 mA

Only one of the above high/low alarm definitions is available in a given configuration. NAMUR NE 43 compliant when high alarm level is selected.

Digital: HART 1200 Baud FSK (frequency shift keyed)

HART impedance requirements must be met to enable communication. Total shunt impedance across the master device connections (excluding the master and transmitter impedance) must be between

230 and 1100 ohms. The transmitter HART receive impedance is defined as:

Rx: 42K ohms and Cx: 14 nF

In point-to-point configuration, analog and digital signalling are available. The instrument may be queried digitally for information, or placed in Burst mode to regularly transmit unsolicited process information digitally. In multi-drop mode, the output current is fixed at 4 mA, and only digital communication is available.

DLC3010 Digital Level Controller Specifications (continued)

Transient Voltage Protection: The loop terminals are protected by a transient voltage suppressor. The specifications are as follows:

Pulse Waveform		Max VCL	Max IPP
Rise Time	Decay to	(Clamping	(Pulse Peak
(ms)	50% (ms)	Voltage) (V)	@ Current) (A)
10	1000	93.6	16
8	20	121	83

Note: μs = microsecond

Ambient Temperature: The combined temperature effect on zero and span without the 249 sensor is less than 0.03% of full scale per degree Kelvin over the operating range -40 to 80_C (-40 to 176_F)

Process Temperature: The torque rate is affected by the process temperature (see figure 1). The process density may also be affected by the process temperature.

Process Density: The sensitivity to error in knowledge of process density is proportional to the differential density of the calibration. If the differential specific gravity is 0.2, an error of 0.02 specific gravity units in knowledge of a process fluid density represents 10% of span.

user, and a small performance loss is acceptable, the instrument could be mounted in 90 degree rotational increments around the pilot shaft axis. The LCD meter may be rotated in 90 degree increments to accommodate this.

Construction Materials

Case and Cover: Low-copper aluminum alloy Internal: Plated steel, aluminum, and stainless steel; encapsulated printed wiring boards; Neodymium Iron Boron Magnets

Electrical Connections

Two 1/2-14 NPT internal conduit connections; one on bottom and one on back of terminal box. M20 adapters available.

Minimum Differential Specific Gravity

With a nominal 4.4 degrees torque tube shaft rotation for a 0 to 100 percent change in liquid level (specific gravity=1), the digital level controller can be adjusted to provide full output for an input range of 5% of nominal input span. This equates to a minimum differential specific gravity of 0.05 with standard volume displacers.

See 249 sensor specifications for standard displacer volumes and standard wall torque tubes. Standard volume for 249C and 249CP is 980 cm3 (60 in3), most others have standard volume of 1640 cm3 (100 in3).

Operating at 5% proportional band will degrade accuracy by a factor of 20. Using a thin wall torque tube, or doubling the displacer volume will each roughly double the effective proportional band. When proportional band of the system drops below 50%, changing displacer or torque tube should be considered if high accuracy is a requirement.

Mounting Positions

Digital level controller can be mounted rightor left-of-displacer, as shown in figure 8.

Instrument orientation is normally with the coupling access door at the bottom, to provide proper drainage of lever chamber and terminal compartment, and to limit gravitational effect on the lever assembly. If alternate drainage is provided by
