Problems to be paid attention to during the installation and use of pressure transmitters
2011-7-18 16:57:45

During the installation and use of the pressure transmitter , special attention should be paid to the correct installation position of the transmitter on the process pipeline, which is related to the measured medium. In order to obtain the best measurement results, the following conditions should be considered:

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

2. When measuring liquid pressure, the pressure taking port should be opened on the side of the process pipeline to avoid sedimentation;

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

4. When measuring the gas pressure, the pressure transmitter pressure port should be opened at the top of the process pipeline, and the transmitter should also be installed at the top of the process pipeline so that the accumulated liquid can be easily injected into the process pipeline

5. Prevent dregs from depositing in the duct;

6. When measuring steam or other high-temperature media, a condenser such as a buffer tube (coil) must be connected, and the operating temperature of the pressure transmitter should not be exceeded;

7. When freezing occurs in winter, it is necessary to take anti-freezing measures according to the transmitter installed outdoors to avoid the expansion of the liquid in the pressure port due to the freezing volume, which will cause the transmitter to be damaged;

8. The pressure guiding tube should be installed in a place with small temperature fluctuations;

9. When wiring, pass the cable through the waterproof joint (accessory) or flexible pipe and tighten the sealing nut to prevent rainwater and other leakage into the transmitter housing through the cable.
