How to Correctly Install and Maintain Pressure Transmitters

The correct installation position of the pressure transmitter on the process pipeline is related to the measured medium. In order to obtain the best measurement effect, the following points should be considered during installation and maintenance:

1. When measuring steam or other high-temperature media, it is necessary to connect a buffer tube (coil) or other condenser to prevent the temperature of the transmitter from exceeding the limit.

2. Prevent the deposition of slag in the conduit.

3. The pressure transmitter should avoid contact with corrosive or overheated media.

4. When measuring gas pressure, the pressure tap should be opened at the top of the process pipeline, and the pressure transmitter should also be installed on the upper part of the process pipeline to facilitate the injection of accumulated liquid into the process pipeline.

5. The pressure guiding pipe should be installed in a place with small temperature fluctuations.

6. When measuring liquid pressure with a pressure transmitter, the pressure tap should be opened on the side of the process pipeline to avoid sedimentation and slag buildup.

7. When wiring, pass the cable through the waterproof connector (accessory) or flexible tube and tighten the sealing nut to prevent rainwater and other liquids from leaking into the transmitter housing through the cable.

8. When the pressure transmitter is frozen in winter, it should be installed outdoors and provided with anti-freezing measures to prevent the liquid in the pressure port from expanding due to freezing, which can cause damage to the sensor.

9. When measuring liquid pressure, the installation position of the transmitter should avoid the impact of liquid (water hammer phenomenon) to prevent damage to the sensor due to overpressure.
