Precautions for using pressure transmitter

- Aug 14, 2020-

1. Do not apply a voltage higher than 36V to the pressure transmitter, otherwise the transmitter will be damaged.

2. Do not touch the pressure transmitter diaphragm with hard objects, otherwise the isolation diaphragm will be damaged.

3. The measuring medium is not allowed to freeze. Otherwise, the sensor element isolation diaphragm will be damaged, resulting in damage to the pressure transmitter UPB13. If necessary, the transmitter should be temperature protected to prevent freezing.

4. When measuring steam or other high-temperature media, the temperature should not exceed the temperature limit when using the transmitter. When the temperature exceed the temperature limit, a heat sink must be used.

5. When measuring steam or other high-temperature media, use a heat pipe to connect the transmitter to the pipeline, and use the pressure on the pipeline to transmit 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. In the process of pressure transmission, the following points should be noted.

a. There should be no leak between the connection of the pressure transmitter UPB1 and the heat pipe.

b. Before starting to use, if the valve is closed, open the valve carefully and slowly to prevent the measured medium from directly hitting the sensor diaphragm and damaging the diaphragm;

c. The pipeline must be kept unobstructed, otherwise the sediment in the pipeline will pop up and damage the sensor diaphragm.
