Some Considerations for Pressure Transmitters

- Jun 12, 2020-

(1) Prevent the pressure transmitter from contacting with corrosive or overheated medium;

(2) Prevent dross from depositing in the conduit of the pressure transmitter UPB2;

(3) When measuring the liquid pressure, the pressure port should be opened on the side of the process pipeline to avoid precipitation and slag accumulation;

(4) When measuring gas pressure, the 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 gas can be easily injected into the process pipeline;

(5) The pressure guiding pipe should be installed in a place with small temperature fluctuation;

(6) When measuring steam or other high-temperature media, a condenser such as a buffer tube (coil) should be connected, and the working temperature of the pressure transmitter UPB8 should not exceed the limit;

(7) When freezing occurs in winter, the pressure transmitter installed outdoors must take anti-freezing measures to avoid the expansion of the liquid in the pressure port due to icing volume, resulting in damage;

(8) When measuring the liquid pressure, the installation position of the pressure transmitter should avoid the impact of the liquid (water hammer phenomenon) to avoid the sensor from being damaged by overpressure;

(9) When wiring the pressure transmitter UPB7, pass the cable through the waterproof connector (accessory) or the flexible tube and tighten the sealing nut to prevent rain water and other leakage through the cable into the pressure transmitter housing.
