What problems should be avoided when using pressure transmitters?

- Jun 03, 2020-

When we are using a pressure transmitter, we need to first check whether there is signal interference around the pressure transmitter. If there is any, it must be eliminated in time. The sensor of the pressure transmitter should be shielded from disconnection between the metal casing and the cable, which can enhance the anti-interference ability of the pressure transmitter. In addition, after we have used the pressure transmitter for a period of time, the mounting hole of the pressure transmitter is easily affected, so we need to clean the mounting hole of the pressure transmitter regularly, and to avoid the pressure transmitter UPB2 is in contact with corrosive or overheated media.

Secondly, when we are wiring, we need to make the the cable go through the waterproof joint or tube and tighten the sealing nut, which can prevent rainwater from entering the pressure transmitter through the cable and damaging the pressure transmitter. When we measure the gas pressure, the pressure inlet of the pressure transmitter should be 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 better injected into the process pipeline.

Finally, if we are using a pressure transmitter UPB13 to measure the pressure of the liquid, the pressure transmitter's pressure port should be opened on the side of the process pipe to avoid sedimentation and accumulation of slag. In addition, the pressure transmitter  cannot use a voltage higher than 36V, otherwise it will be damaged.
