Pressure transmitter routine maintenance method

After a user purchases a pressure transmitter, wear is inevitable during the use of the pressure transmitter. Failures are inevitable. At this time, the daily maintenance of the pressure transmitter is very important. Today, Xiao Bian has come for everyone. Describe the daily maintenance method of pressure transmitter. 　　

1. The pressure transmitter should first be prevented from coming into contact with corrosive or overheated media.

2. When measuring the liquid pressure, the pressure tap should be opened on the side of the process piping to avoid sedimentation.

3. Prevent dross deposition in the duct.

4. The pressure tube should be installed in places where temperature fluctuations are small.

5. When measuring gas pressure, the pressure tap should be open at the top of the process pipe, and the pressure transmitter should also be installed in the flow. The top of the pipeline is so that the accumulated liquid can be easily injected into the process piping.

6. When freezing occurs in winter, the transmitter installed outdoors must adopt anti-freezing measures to avoid the loss of the sensor due to the expansion of the volume of the ice in the pressure-inducing port.

7. When freezing occurs in winter, the transmitter installed outdoors must adopt anti-freezing measures to avoid the loss of the sensor due to the expansion of the volume of ice in the pressure-inducing port.

8. When wiring, pass the cable through the waterproof connector or the coiled tube and tighten the sealing nut to prevent rain water from leaking through the cable into the transmitter housing.

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

The daily maintenance method of the pressure transmitter has been introduced. After the user uses the pressure transmitter, you can refer to the above maintenance method. This way, the daily maintenance can reduce the wear of the instrument and the generation of the failure. This is for the user. Knowledge is very important.
