Gas leak detector


Leak detection, air tightness detection and predictive maintenance, products and solutions in steel and non-ferrous metals, tobacco and food and beverage, automobile manufacturing, chemical industry and oil and gas, mining Cement, glass manufacturing, power and cleaning systems, military industry, paper and printing, railway transportation, water treatment, infrastructure, subway fans and large air-conditioning systems, port automation and many other industries are widely used. The ultrasonic leak detection system of the ultrasonic detector is different from the specific gas sensor which is limited by the specific gas it is designed to sense, but detects by sound. Any gas passing through the leak hole will produce eddy currents, and there will be part of the ultrasonic wave band, so that the leak detection system of the ultrasonic detector can sense any kind of gas leakage. Scanning with the leak detection system of the ultrasonic detector, you can hear the leakage sound from the earphone or see the change of the digital signal. The closer to the leak point, the more obvious. If the on-site environment is noisy, a rubber tube can be used to reduce the receiving area and shield against ultrasonic waves. In addition, the frequency adjustment capability of the leak detection system of the ultrasonic detector also reduces background noise interference. It can check the air pressure system, test the pressure cable used by the telecommunications company, etc. Tanks, pipes, and hoses can all be tested by pressurization. As well as vacuum systems, vortex exhaust, diesel engine fuel intake systems, vacuum chambers, ship compartments, watertight doors, material handling systems, pressure vessels and pipelines for internal and external gas-liquid leakage. It is suitable for the sealing test of flexible packaging parts in food, pharmaceutical, daily chemical and other industries. It can also carry out the sealing performance test of the specimen after the drop and pressure test.

Test principle

By evacuating the vacuum chamber, the sample immersed in water will generate internal and external pressure difference to observe the gas escape from the sample , To determine the sealing performance of the sample; by evacuating the vacuum chamber to generate a pressure difference between the inside and outside of the sample, observing the sample expansion and the recovery of the shape of the sample after releasing the vacuum, so as to determine the sealing performance of the sample.
