A vacuum leak detector is a special device used to detect gas leaks in a vacuum system or sealed container. Its core principle is to determine the leak location and leak rate by monitoring pressure changes, gas composition, or ionization signals.

Working principle of the vacuum leak tester

Vacuum pressure method: A low-pressure environment is formed by vacuuming, and a high-sensitivity pressure sensor is used to monitor pressure changes. If there is a leak in the object being tested, external gas will enter and cause the pressure to rise, thereby calculating the leak rate. For example, a vacuum tester evaluates the sealing of a package by simulating a vacuum environment.
Ionization charge technology: The vacuum detector uses ionization charge sampling technology. The vacuum degree in the vacuum interrupter chamber is precisely corresponds to the ionization charge amount, and the vacuum degree value is directly displayed, which is suitable for power equipment testing.

Application of a vacuum leak detector

Packaging industry: Detect the sealing of containers such as glass bottles and metal cans, such as vacuum water testers.
Electric power equipment: Vacuum measurement of the arc extinguishing chamber of vacuum switches, and the equipment life can be evaluated without disassembly.
Industrial manufacturing: Detect equipment sealing performance or product defects, such as high-frequency discharge technology for judging the sealing effect of test tubes.

Sealing performance detection

Non-contact online detection: Used for rapid detection of packaging containers such as glass bottles and metal cans, such as anti-theft cap sealing products in the condiment industry, with a detection speed of 400-800 bottles/minute
Vacuum water test: Simulate vacuum environment, judge leakage by observing pressure changes or bubble generation, suitable for food and drug packaging sealing evaluation
Industrial equipment sealing inspection: Detect leakage of vacuum pumps, pipelines, and containers to ensure the normal operation of equipment in a vacuum environment

Leak location and leak rate calculation

Pressure change monitoring: Real-time monitoring of pressure changes in the vacuum chamber through high-sensitivity sensors, and accurate calculation of leak rates (such as vacuum leak detection boxes and leak testers).
