TO MEASURE PRESSURE

The TRX-II Pressure Sensor Option

Pressure Sensor Identification
1. Sensor.
2. Cable 1,5 metres.
All sensors carry s/n pressure range in psi/bar.

Preparation

To change the pressure unit see the section "Pressure Units Setting".
When using a sensor for the first time with a TRX-II, specific data
must be entered in the TRX-II memory and the sensor calibrated.
Refer to the section "Pressure Sensor" on page 40.

General

Important notes:
1. To reset each pressure sensor reading to zero, press zero key.
2. Make sure that tubing or hose is used within manufacturer's
pressure and temperature limits.
3. For pressures over 150 psi (10 bar) use a special small inner
diameter hose to limit the fluid flow and expansion in case a
connection starts leaking.
4. Do not use the plastic tubing connector for pressures over
150 psi (10 bar).
5. To prevent damage to the sensor, applied pressure should not
exceed the specified containment pressure.
6. Make sure that the connector and sensor materials are
compatible with the fluid.
7. To avoid leakage and excessive force on the sensor, use sealing
tape and two (2) wrenches.
8. Perform calibration in accordance to your company standard
procedures.

Operating the TRX-II with Pressure Sensor

Plug in connector into the TRX-II. Switch the TRX-II calibrator on
after you have made the proper preparations. Select PRESSURE in
the measure menu and none in the source menu.
K319 Issue 2
The pressure sensor has been designed
to calibrate pressure instruments in
conjunction with the TRX-II multi-
calibrator. The pressure sensor is
powered from the TRX-II calibrator. It
allows pressure instrument calibrations
with ranges from:
•-15 psi up to 10 000 psi
•-1 bar up to 700 bar).
