Precautions for the use of pressure transmitters

by:Sure     2021-08-05
Precautions for the use of pressure transmitter 1: Do not apply a voltage higher than 36V to the transmitter, which may cause damage to the transmitter; 2: Do not touch the diaphragm with hard objects, which may damage the isolation diaphragm; 3: The measuring medium is not allowed to freeze, otherwise it will damage the sensor element isolation diaphragm and cause damage to the transmitter. If necessary, the transmitter needs to be temperature protected to prevent freezing; 4: Precautions for the use of the pressure transmitter under measurement 1 : Do not apply a voltage higher than 36V to the transmitter, which will damage the transmitter; 2: Do not touch the diaphragm with hard objects, which will damage the isolation diaphragm; 3: The measured medium is not allowed to freeze, otherwise The sensor element isolation diaphragm will be damaged, causing damage to the transmitter. If necessary, temperature protection of the transmitter is required to prevent freezing; 4: When measuring steam or other high-temperature media, the temperature should not exceed the use of the transmitter When the limit temperature is higher than the limit temperature used by the transmitter, a heat sink must be used; 5: When measuring steam or other high-temperature media, a radiator pipe should be used to connect the transmitter and the pipe together, and use the pressure on the pipe To the transformer. When the measured medium is water vapor, an appropriate amount of water should be injected into the radiating pipe to prevent the superheated steam from directly contacting the transmitter and damaging the sensor; 6: During the pressure transmission process, pay attention to the following points: 1), change Do not leak air at the connection between the transmitter and the radiating pipe; 2) Before use, if the valve is closed, you should open the valve very carefully and slowly during use to prevent the measured medium from directly impacting the sensor diaphragm. Damage the sensor diaphragm; 3). The pipeline must be kept unobstructed, the sediment in the pipeline will pop up and damage the sensor diaphragm
