Gas sensors can provide detection for a variety of various industrial applications. In the field of natural gas and combustible gas detection, the GMS20F-5 has been regarded as a reliable detector.

The GMS20F-5 is a 20 Series type gas detector which utilizes semiconductor technology to detect combustible gases such as propane, methane, butane, etc. It can detect a wide range of concentrations from 0 to 100% of the Lower Explosion Level (LEL). It has both digital display and analogue output capability, and is equipped with an alarm for monitoring gases in hazardous environments.

In terms of technical specifications, GMS20F-5 has built-in temperature sensors and can perform accurately with better reliability in a wider temperature range. It is highly immune to electromagnetic interference and has good EMI performance, which ensures reliable operation in the electrically noisy environment. In terms of safety, GMS20F-5 over-voltage and under-voltage protection, reverse polarity protection, and overload protection.

The working principle of GMS20F-5 is based on the semiconductor detection technology. The detector uses a small internal heater to raise the temperature of the semiconductor chip, which then changes its electrical conductivity when exposed to a combustible gas. The variation of the electrical conductivity in turn results in the output current variation and can be detected by the detector.

In addition, the GMS20F-5 is equipped with a self-check function to constantly monitor its own performance. The self-test consists of a signal outputted by the detector every 30 seconds, enabling the end user to identify if any fault or deterioration is taking place. It is especially helpful in ensuring the reliability and safety of the gas detection system.

The GMS20F-5 gas detector has found many successful applications in gas industries, water and wastewater treatment plants, petrochemical and refining operations, food and beverage processing facilities, public transportation, construction sites, fire and rescue, and other hazardous areas.

Overall, the GMS20F-5 gas detector is an all-in-one solution designed for detection of combustible gases in hazardous environments. With its reliable semiconductor technology, digital display, analogue output, wide temperature range, and self-testing functions, it is a reliable and cost-effective solution for gas safety in industrial and commercial applications.
