The air tightness test equipment comprises an air source, a gas delivery pipe, a test solenoid valve, a controller, a timer, a pressure transmitter and an alarm, one end of the gas delivery pipe is connected with the gas source, and the other end is connected with the air hole, the test solenoid valve is connected in the gas delivery pipe, the pressure transmitter is connected in the gas transmission pipe between the air hole and the test solenoid valve, and the pressure transmitter, timer and alarm are all connected with the controller. The pressure transmitter in the hermetic equipment adopts diaphragm isolation technology, integrated chip, good stability and fast response. The pressure transmitter has a good accuracy class and is able to achieve an accuracy level of 0.1% FS. The pressure transmitter is easy to install and can be connected with threads or clamps. Thread sizes can be customized to meet specific needs. The pressure transmitter adopts a cut-off design and has strong anti-interference ability. The current type pressure transmitter also has current limiting, voltage limiting, and reverse polarity protection. Pressure transmitters are indispensable instruments in hermetic equipment. The quality of the pressure transmitter directly determines the quality of the airtight equipment. Today’s airtight devices are becoming more and more widely used. From the previous automobile manufacturing, it has expanded to the current daily necessities, household appliances, food industry, medical industry, and so on. With the continuous development of pressure transmitter technology, it will also make the air tightness detection technology further develop in the direction of higher progress, high efficiency and intelligence.
