Precautions for using pressure sensors

During the use of pressure sensors, we need to pay attention to the following matters

1. Prevent the transmitter from coming into contact with corrosive or overheated media;

2. Prevent sediment from settling inside the conduit;

3. When measuring liquid pressure, the pressure tap should be opened on the side of the process pipeline to avoid sedimentation and slag accumulation;

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

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

6. When measuring steam or other high-temperature media, it is necessary to connect a buffer tube (coil) or other condenser, and the working temperature of the transmitter should not exceed the limit;

7. When freezing occurs in winter, transmitters installed outdoors must take anti freezing measures to prevent the liquid in the pressure inlet from expanding due to freezing volume, which may cause damage to the sensor;

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

9. When wiring, thread the cable through the waterproof joint (accessory) or flexible tube and tighten the sealing nut to prevent rainwater and other substances from leaking into the transmitter housing through the cable.
