Pressure transmitter of matters needing attention in use1

The matters of attention in the pressure transmitter using

1, guide pressure pipe shall be installed where small temperature fluctuations.

2, measuring gas pressure, the pressure should be open at the top of the process piping, and sensors should be installed in the upper process pipeline, so that the accumulated liquid injection process pipeline easily.

3, measuring, liquid pressure sensor installation location should avoid the impact of the liquid ( Water hammer) In order to avoid sensor overvoltage damage.

4, connection, cable through the waterproof connector or round tube and screw down the sealing nut, such as in case of rain through the cable leakage into the transmitter inside the shell.

5, prevent the dross in intraductal deposition and sensor and corrosive medium contact or overheating.

6, winter freeze occurs, installed in the outdoor sensor anti-freezing measures must be adopted to avoid bring pressure inside the liquid due to the icing volume expansion, causes loss of sensors.

7, measuring the liquid pressure, with the side of the mouth should be open in the process piping, to avoid deposit product residue.

8, measuring, steam or other high temperature medium to connect with the buffer tube ( Coil) Such as condenser, should not make the sensor operating temperature more than limit.
