The instrument detects the pressure drop per unit time through a high-precision pressure sensor. The system has simple structure, high reliability and low maintenance cost. It is convenient for large-volume long-time pressure monitoring and leakage detection
Performance characteristics
By filling compressed air of specified pressure into the measured object (product), this instrument detects whether there is leakage according to the change of its internal pressure. Firstly, the leak detector fills the measured object with the regulated gas, and then stops the inflation to maintain pressure. During the pressure maintaining process, it senses the pressure drop caused by leakage, that is, direct pressure leakage rate, through a high sensitivity pressure sensor.
