Precautions for pressure transmitters

by:Sure     2021-08-07
1: Do not apply a voltage higher than 36V to the transmitter, which may damage the transmitter; 2: Do not touch the diaphragm with hard objects, which may damage the isolation diaphragm; 3: The measured 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: When measuring steam or other high-temperature media, its temperature 1: Do not use high Applying a voltage of 36V to the transmitter will cause damage to the transmitter; 2: Do not touch the diaphragm with hard objects to cause damage to the isolation diaphragm; 3: The measured medium is not allowed to freeze, otherwise it will damage the sensor element isolation Diaphragm, 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, its temperature should not exceed the limit temperature of the transmitter when it is used. A heat sink must be used when the temperature is higher than the limit temperature used by the transmitter; 5: When measuring steam or other high-temperature media, a heat sink should be used to connect the transmitter and the pipeline together, and use the pressure on the pipeline to transmit 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 to the sensor diaphragm; 3) The pipeline must be kept unobstructed, the sediment in the pipeline will pop up and damage the sensor diaphragm;
