Daily precautions for pressure transmitters

- Jul 15, 2020-

1. Do not apply voltage higher than 36V to the pressure transmitter, causing damage to the transmitter;

2. Do not touch the diaphragm with a hard object, causing the diaphragm to be damaged;

3. The measured medium is not allowed to freeze, otherwise it will damage the sensor diaphragm and cause damage to the transmitter. If necessary, the pressure transmitter UPB1 must be temperature-protected to prevent freezing;

4. When measuring steam or other high-temperature media, the temperature should not exceed the limit temperature of the transmitter when it is used, and the heat sink must be used when the temperature of measured media is higher than the limit temperature of the pressure transmitter;

5. When measuring steam or other high-temperature media, heat pipes should be used to connect the transmitter and the pipeline together, and transmit the pressure on the pipeline to the transmitter. When the measured medium is the water vapor, an appropriate amount of water should be injected into the heat tube to prevent the superheated steam from directly contacting the transmitter and damaging the product;

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

a. Do not leak air at the connection between the pressure transmitter and the heat pipe;

b. If the valve is closed before use, it should be opened very carefully and slowly to prevent the measured medium from directly impacting the sensor diaphragm and damaging the sensor.
