Pressure transmitter of matters needing attention in use

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 the upper thermocouple sensor should be installed in process, so that the accumulated liquid injection process pipeline easily.

3, measuring pressure, the liquid of the thermocouple sensor installation location should avoid the impact of the liquid ( Water hammer) To avoid thermocouple sensor damage of overpressure.

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 thermocouple sensor and corrosive medium contact or overheating.

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

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 have caused more than limit working temperature of thermocouple sensor.
