  • Why is the pressure transmitter damaged? Pay attention to what?
    release time:2021-02-02 09:10:06hit count:

           The pressure transmitter will be damaged during use. Let's take a look at the reasons for the damage of the pressure transmitter!

           1. In the process of pressure transmission, pay attention to the connection between the transmitter and the radiating pipe to avoid air leakage. The pipeline must be kept unobstructed. The sediment in the pipeline will pop up and damage the sensor diaphragm. If the valve is closed before use, you should open the valve very carefully and slowly during use to prevent the measured medium from directly impacting the sensor diaphragm and damaging the sensor diaphragm.

           2. When measuring steam or other high-temperature media, heat pipes should be used to connect the pressure transmitter and the pipeline together, and use the pressure on the pipeline to transfer to the change. If the valve is closed before use, it should be very Open the valve carefully and slowly to prevent the measured medium from directly impacting the sensor diaphragm and damaging the sensor diaphragm.

           3. Do not touch the diaphragm with hard objects, which may damage the isolation diaphragm.

           4. The measured medium is not allowed to freeze, otherwise it will damage the sensor element isolation diaphragm and cause damage to the pressure transmitter. If necessary, temperature protection of the transmitter is required to prevent freezing.

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

           6. Do not apply a voltage higher than 36V to the transmitter, which may damage the transmitter.

           I must have a general understanding of the causes of the pressure transmitter, and know what problems will cause the damage of the pressure transmitter. In the future use, avoid these problems as much as possible, so as to reduce and avoid pressure transmission. Failure and damage of the device.
