Overpressure protection device diaphragm pressure gauge
1) USE: Diaphragm pressure gauge also known as micro pressure meter, mainly used to test the low pressure pipeline gas pressure.
2) Weakness of diaphragm pressure gauge: Due to the low detection pressure, the sensitive elastic element diaphragm should have a very high sensitivity but also very fragile. If the applied pressure source exceeds the upper limit of the measurement pressure , the diaphragm will be permanently deformed and fail.
3) Function of overpressure protection device : When the measured medium pressure exceeds the upper limit of the measured pressure, the diaphragm with overpressure protection device will not be permanently deformed and fail. After releasing the pressure source beyond the upper limit of the measurement, the diaphragm pressure gauge can work normally.
