Calibrating a P/I Transmitter

Calibrating a P/I Transmitter

To calibrate a P/I (pressure to current) transmitter, apply a pressure to the transmitter and measure the transmitter’s current loop output. You can apply pressure with the

Calibrator’s internal pump or with an external pump. An internal relief valve activates when pressure/vacuum exceeds the rating for the Calibrator model (50-60 psi for

718 30G, 140-150 psi for 718 100G.)

W

Warning

To avoid a violent release of pressure or vacuum, always depressurize the system slowly using the pressure/vacuum release control before detaching any pressure line.

Using the Internal Pump

The internal pump can provide 30 psi (2.0685 bar) for

Model 718 30G or 100 psi (6.895 bar) for Model 718

100G.

The preferred use for the internal pump is shown in Figure

4, where the calibrator displays pressure measured with the internal sensor and provided by the internal pump.

The internal pump can also be used with certain Fluke

700 Series Pressure Modules. In this case, pressure measured by the Pressure Module is displayed by the

Calibrator. Appropriate Pressure Modules for each

9

718 30G/100G

Users Manual

calibrator model are identified in Table . Figure 5 shows the internal pump being used with a pressure module.

W

Warning

If both a pressure module and the internal sensor are connected, the Calibrator displays

ONLY the pressure module measurement.

To use the Calibrator’s internal pump, refer to Figure 3 and perform the following steps:

1. Depressurize the line before connecting the

Calibrator.

2. Connect the pressure transmitter to the calibrator internal sensor as shown in Figure 4 (for internal pressure sensor measurements) or Figure 5 (for pressure module measurements.)

Note

To avoid leaks, use Teflon tape or similar sealant on all pressure connections.

3. Make sure the pressure/vacuum switch is in the desired position. Forward (clockwise) is for pressure; backward (counter-clockwise) is for vacuum.

4. Turn the pressure/vacuum release control backward

(counter-clockwise) to vent pressure/vacuum from the pump.

5. Press to zero the pressure display.

6. Turn the fine adjustment knob to mid-range.

7. Turn the pressure/vacuum release control forward

(clockwise) to close the release valve.

8. Work the pump handle in and out to apply incrementally larger pressure/vacuum changes.

Shorten the stroke to apply smaller increments of pressure/vacuum change.

9. To make very small pressure/vacuum changes, use the fine adjustment knob.

Note

This knob adjusts a small internal reservoir to vary the total volume. With larger external pressure/vacuum volumes, this control will adjust pressure or vacuum within a smaller range.

10. Depressurize the system before disconnecting the pressure line.
