Attention to the use of differential pressure transmitter

 


Attention to the use of differential pressure transmitter:

1: Do not apply voltage higher than 36V to the transmitter, resulting in damage to the transmitter;

2: Do not touch the diaphragm with a hard object, resulting in damage to the isolation diaphragm;

3: The measured medium is not allowed to freeze, otherwise the sensor element isolation diaphragm will be damaged, resulting in damage to the transmitter. If necessary, the transmitter should be temperature-protected to prevent freezing.

4: When measuring steam or other high temperature medium, the temperature should not exceed the limit temperature when the transmitter is used, and the heat sink must be used above the limit temperature used by the transmitter;

5: When measuring steam or other high temperature media, use a heat pipe to connect the transmitter to the pipe and use the pressure on the pipe to transfer it to the transformer. When the measured medium is water vapor, an appropriate amount of water should be injected into the heat pipe to prevent the superheated steam from directly contacting the transmitter and damaging the sensor;

6: During the pressure transmission process, the following points should be noted.

a, the transmitter and the heat pipe connection, do not leak;

b. Before starting to use, if the valve is closed, the valve should be opened very carefully and slowly, so as to prevent the measured medium from directly impacting the sensor diaphragm and damaging the sensor diaphragm;

c. The pipeline must be kept clear, the deposits in the pipeline will pop out, and the sensor diaphragm will be damaged;
