The Dynisco IPX II Series of Smart Pressure Transmitters are microprocessor based instruments that incorporate advanced software techniques and modern sensor design. New, proprietary sensor processing methods ensure the highest quality and reliability to meet Dynisco’s standards.

The IPX II Series is designed for applications that require high accuracy, even under wide variations in process temperature. With the capability for up to 6-to-1 span turndown, one pressure range can be used in several different applications, reducing spare parts inventory. And the IPX II Series’ remote digital communication utilizing the industry standard HART protocol allows transmitter parameter changes to be made from safe areas, increasing operator safety.

The IPX II Series of Smart Pressure Transmitters are characterized for process temperature effects, providing an optional linearized stable, temperature reading via 4-20 mA output. Figure 4-1 illustrates the operation of the transmitter in the form of a block diagram. The process temperature signal is available through the HART protocol. An optional dual LCD will display pressure or temperature measurements in real-time.

In addition to the standard analog output, the IPX II Series supports remote digital communications compatible with the HART Communicator (product of Emerson). The Model 275 can communicate with IPX II Series transmitters from the control room, at the transmitter site, or from any convenient junction box or wiring termination point in the measurement loop. The model 275 may be used to configure the IPX II Series of transmitters or to test the control loop.

The IPX II Smart Pressure Transmitter is a microprocessor-based device capable of measuring process pressure to within 0.15% of the specified range. It is compensated for temperature effects at the process end as well as the electronics end by using RTD’s and compensating software customized for each unit.

The IPX II Series can be broken down into two distinct subsections, mechanical and electrical. The following describes each in detail.

CHANICALCHANICAL

CHANICAL

The mechanical system (filled assembly) consists of a lower diaphragm, a filled capillary tube, and an upper diaphragm with a sputtered thin film strain gage. The filled assembly transmits pressure from the process to the strain gage diaphragm where it is converted to an electrical signal. The filled assembly isolates the electronics from the high process temperatures.

The lower diaphragm is the surface in contact with the media being measured. This diaphragm can be made from a choice of materials. The standard material is heat-treated 15-5 stainless steel. This has average corrosion and abrasion resistance and is similar to 17-4 stainless steel. Other materials are

24

FUNCTION

also available including Hastelloy C-276 which has excellent corrosion resistant properties (but is not good for abrasion). For other materials please consult the factory.

Behind the lower diaphragm is a capillary tube filled to the upper diaphragm. As the process pressure deflects the lower diaphragm, the fill is displaced through the capillary tube to deflect the upper diaphragm.

The upper diaphragm has a 5000 ohm thin film strain gage element deposited on it in the configuration of a Wheatstone Bridge. The deflection of the upper diaphragm causes a change in the resistance of the strain gage and hence a change in the balance of the bridge. The amount of imbalance is directly proportional to the applied pressure. This completes the translation of pressure applied to the lower diaphragm into a usable electrical signal.

4.2.34.2.3

4.2.3

EE

E

LELE

LE

CTRICALCTRICAL

CTRICAL

The low level output signal from the bridge is amplified via an instrumentation amp circuit. The amplified signal then goes to the input of the analog-to-digital (A/D) converter.

Once the microprocessor has the converted voltage input from the A/D converter, the compensation algorithms are executed. The unit is compensated for any errors introduced by temperature effects on the gauge, snout electronics, and the nonlinearities of the pressure measurement itself. The corrected digital signal is sent to a digital-to-analog (D/A) converter which modulates the current of the unit’s power supply between 4 and 20 milliamps for an output current proportional to the applied pressure.

The IPX II Series Smart Pressure Transmitter housing has two “feet” used for mounting on a flat surface or on a pipe using a u-bolt pipe mounting bracket, see Figure 7-1.

The optional 2” Pipe Mounting Bracket kit can be supplied with the process electronics housing. This mounting bracket can be set-up in a number of different orientations. The metal plate is attached to the process housing with the kit’s enclosed hardware.

To remove the cover of the IPX II in a hazardous location the power to the transmitter must be off. With the Intrinsically Safe product, galvanic barrier limits the power so it is safe to remove cover.

In addition, if the LCD display option is utilized, the electronics inside the housing can be rotated in 90o intervals. To do this remove the two 6-32 machined screws, rotate the electronics to the required position, and replace the two machined screws. Note the position of the screws may change depending on the position of the electronics module.

With the power supply off, connect the (+) side of the power supply to the (+) OUT terminal of the electronics module. Connect the (-) side of the power supply through a 250Ω resistor to the (-) OUT terminal of the electronics module. See Figure 7-2. Connect the input terminals 1 and 3 in series with the current loop to be measured. Terminal 1 should be more positive than 3.

Current Input High (+MA) Current Input Low (-COM)

The output can be monitored by connecting a multi-meter in series with either of the two output terminals, or by connecting a high impedance voltmeter across the 250Ω resistor. Turn on the power supply. In about 5 seconds the IPX II Series Smart Pressure Transmitter loop current will settle to its normal value in the range of 4 to 20 mA.

If the unit has been ordered with optional dual LCD display, the display and display adapter must be removed to connect the 24 V dc power to the unit. The display pulls off the display adapter, see Figure 7-3.

There are two types of display adapters, the standard without a second 4-20mA output for temperature or an adapter with a second 4-20 mA output for temperature. The display adapter is connected through standoff posts by two 6-32 screws.

If the IPX II Series Smart Pressure Transmitter was ordered with the display option, it has a small local dual LCD display module plugged into the display adapter. The display option can be ordered from the factory installed on the IPX II Series Smart Pressure Transmitter or can be ordered at a later date and installed on site. Having the display option as part of the IPX II Series Smart Pressure Transmitter does not affect its operation in the analog mode and the description of the previous section applies.

However, the display option does provide some very useful local indication of the measured pressure, temperature and other diagnostic functions. Figure 7-4 below indicates the arrangement of the display screen and some of the symbols that are available.

The top row displays the measured variable. A minus sign can be displayed if applicable. Depending on the input selected the number of decimal places displayed changes.

The mid portion is an analog bar graph display showing the % of range based on the ZERO and FULL-SCALE setting of the IPX II Series Smart Pressure Transmitter. When power is applied, the leftmost segment of the bar graph, the 0%, and the 100% become energized. If the input signal is below what the ZERO is set to, then the left arrow is energized. If the input signal is above the FULLSCALE setting, then the right arrow becomes energized.

The bottom portion of the LCD is capable of displaying alphanumeric messages. In normal operation this row shows a label, which is factory set to display the model number and pressure unit. Seven or eight characters are available per screen. The user may order a desired label in place of the model number.

This LCD display takes full advantage of the precision of the IPX II Series Smart Pressure Transmitter. The digital display of the measurement does not include the small D/A error present in the analog output. It provides highly accurate local indication of the measurement, local fault diagnostics, and the IPX II Series Smart Pressure Transmitter identification. The LCD continues to display the measured variable even if it is beyond the zero and span limits set for the analog output. The value of this display as a set-up, calibration and reconfiguration tool may even be greater.

Once the IPX II Series Smart Pressure Transmitter is powered up, the display comes on in the standard operating mode. With the standard factory set-up and precess sensor connected, the dual LCD display will give the following indication:

Note that when more than seven or eight characters are required to describe a function’s label, the display will continuously alternate through multiple screens. In this section of the manual, placing two or more display messages adjacently indicates alternating displays, as above. The dual LCD display, with some functions, will display a numeric value on the top line of the display in addition to a message on the lower display line.

The IPX II Smart Pressure transmitter may display a pressure, this is caused by the difference in the elevation between the sensor and process connection. This is corrected in a set-up procedure called Set Position Adjust.

Please note that if the display is plugged into the IPX II while it is powered up, the menu sequence may not start at the beginning. To return the display to the normal operating mode power down the IPX II without disconnecting the display or simply wait about two minutes for the transmitter to reset itself.

ESD sensitive component. Electrostatic discharge may damage the PT. Take ESD precautions.

Always remove the PT before cleaning the machine with abrasives or steel wire brushes or suchlike.

Before removing the PT, the medium must be in molten condition.

Removing the transmitter with the medium in solidified condition can damage the diaphragm of the PT.

Do not clean the screw-in section of the PT with hard objects. This will damage the PT!

Always use a torque wrench applied to the designated hexagon collar when screwing the PT in and out. Do not apply the tool to the housing or housing/sensor connection!

• Remove the PT.

• Carefully clean the diaphragm of the transmitter with a soft cloth, while the medium is still malleable.

s:s:

s:

1 . Verify loop current and voltage on the Field device. Almost all field devices need at least 4 mA

and 12 V dc to operate properly.

2. If the field device is set for multidrop mode then set HART Communicator to digital polling mode?

3. Inspection of the loop wiring can often times reveal problems. The shield is normally grounded.

4. Does the control system have HART communication capabilities? Is it configured to communicate HART currently? If so, is it reporting communication problems? If not, stop HART communications on the control system and test communication with the 275 HART Communicator again.

5. If an Analog input point verify that the loop has a minimum of

22

2

50 ohms50 ohms

50 ohms resistance. This can be calculated by measuring the dc voltage across the control system field termination blocks and dividing the current that the transmitter is currently putting on the loop (i.e. Voltage = Current * Resistance ----- Resistance = Voltage / Current) or consulting the control system manuals for value. Regardless of the value measured, add an additional

22

2

50 ohms50 ohms

50 ohms of resistance in series with the loop and place 275 HART Communicator leads across resistor and verify if communication is restored. See Figure 10-1.

6. Try placing an external 0.1 microfarad (uF) to 0.22uF (Capacitor parameters: working voltage: 100 V dc, no polarity) across the terminal blocks going out to transmitter. Verify if communication has been restored to the loop by connecting the 275 Communicator. If communication improves, this may indicate a noise problem. See Figure 10-1.

7. If step 6 allows communication, but not reliably then try adding an additional

22

2

50 ohms50 ohms

50 ohms of

resistance in series with the loop. Be careful. Do not put too much load for a given voltage.

8. If an oscilloscope is available for use then use it to look for noise on the loop. It is necessary to use a scope with differential mode capability to avoid grounding one side of the loop. Noise with a frequency of 800 to 3300 Hz is of particular interest, as this represents frequencies near the HART frequencies of 1200 and 2200 Hz.
