Applications and principles of the gas leakage detector

A Gas leakage detector is used for leak detection, gas tightness testing, and predictive maintenance. The detection of ultrasonic waves usually refers to the frequency band higher than 20 kHz, while the upper limit of the human ear can receive 16.5 kHz, and the use of this characteristic, ultrasonic waves are perfectly applied to industrial detection. Here are some answers.

Where is the Gas leakage detector used?

A Gas leakage detector is used in leak detection, gas tightness testing, and predictive maintenance. Products and solutions are used in steel and non-ferrous metals, tobacco and food and beverage, automotive, chemical and oil and gas, mining and cement, glass manufacturing, power and cleaning systems, military, paper and printing, railroad transportation, water treatment, infrastructure, subway fans, and large air conditioning systems, ports Automation and many other industries are widely used.

What is the principle of the Gas leakage detector?

The Gas leakage alarm leak detection system is not limited to the specific gas it is designed to sense, but rather to the sound it detects. Any gas passing through a leak hole will generate eddy currents, which are part of the ultrasonic waveband, making the Gas leakage detector capable of detecting any type of gas leak. By scanning with the Gas leakage detector, you can hear the leak through the headphones or see the digital signal change. The closer you get to the leak, the more visible it becomes. If the site environment is noisy, rubber tubes can be used to narrow the receiving area and shield against ultrasonic waves. In addition, the Gas leakage detector leakage detection system frequency adjustment ability also makes the background noise interference reduced. Can check the air pressure system, test the pressure cable used by the telecommunications company, etc. Barrel tanks, pipes, and hoses can be detected by pressurization. As well as vacuum systems, vortex exhaust, diesel engine fuel intake system, vacuum chamber, ship compartment, watertight doors, material handling systems, pressure vessels and pipelines inside and outside the gas and liquid leakage. It is suitable for sealing tests of soft packaging parts in food, pharmaceutical, daily chemical, and other industries. It can also be used to test the sealing performance of the specimen after the drop and pressure test.

Gas leakage detector test principle.

Gas leakage detector adopts high-performance sensitive components as the detection sensor, controlled by a powerful microprocessor, with large-scale digital integrated circuits and micro-power components, the air combustible gas concentration signal into electrical signals, by the LCD intuitive digital display. A Gas leakage detector is a high-performance industrial leak detector, when detecting combustible gases, the gas leakage detector is high performance. When detecting combustible gases, the instrument will issue a visible and audible alarm signal. The sensitivity of the instrument can be adjusted, with a leak level indicator, easy to find the gas leakage situation on site. Standalone gas leakage detector with LCD indicator through the vacuum chamber, so that the specimen is immersed in water to produce the pressure difference between the inside and outside, to observe the gas in the specimen escape, and to determine the sealing performance of the specimen. The Gas leakage detector determines the sealing performance of a specimen by evacuating the vacuum chamber, creating a pressure difference between the inside and outside of the specimen, and observing the expansion of the specimen and the recovery of the specimen shape after releasing the vacuum.
