With the use of pressure sensors, it is about the daily maintenance of the pressure sensor. Proper maintenance of the pressure sensor can effectively improve the service life of the sensor, and it can be stable and more accurate when using the sensor. Here are some tips on the daily use and maintenance of pressure sensors:

1. Prevent dross from depositing in the conduit and contact the sensor with corrosive or superheated media.

2. When measuring the gas pressure, the pressure tap should be opened at the top of the process pipe, and the sensor should also be installed in the upper part of the process pipe so that the accumulated liquid can be easily injected into the process pipe.

3. When measuring the liquid pressure, the pressure tap should be opened on the side of the process pipe to avoid depositing slag.

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

5. When measuring the liquid pressure, the installation position of the sensor should avoid the impact of the liquid (water hammer phenomenon), so as to avoid the sensor over-voltage damage.

6. When freezing occurs in winter, the sensor installed outside should adopt anti-freezing measures to prevent the liquid in the pressure-inducing port from expanding due to the volume of ice, resulting in loss of the sensor.

7. When wiring, pass the cable through the waterproof joint or the winding tube and tighten the sealing nut to prevent rainwater from leaking into the transmitter housing through the cable.

8. When measuring steam or other high-temperature medium, it is necessary to add a condenser such as a buffer tube (coil), and the operating temperature of the sensor should not exceed the limit.
