Two Frequent Types for Combustible‑Gas Detectors
For your better understanding of combustible gas detectors, we will start with two common types widely‑seen in daily‑life‑related scenarios.
Fixed‑mount Combustible Gas Detector
The on‑line combustible gas detection alarm mainly consists of a gas detection alarm controller and fixed combustible gas detectors. The controller can be placed in the duty room to monitor each measuring point. Combustible gas detectors are installed at locations prone to gas leakage, with built‑in gas sensors as their core components.
The fixed detector converts combustible‑gas concentration measured by the sensor into electrical signals, which are transmitted to the alarm controller via cables. Higher gas concentration corresponds to stronger electrical signals. When the gas concentration reaches or exceeds the alarm threshold preset by the controller, the alarm triggers. It can activate external devices such as solenoid valves and exhaust fans to eliminate potential hazards automatically.
Portable Combustible Gas Detector
The portable combustible gas detector measures gas concentration by natural diffusion. Equipped with catalytic combustion sensors, it delivers excellent sensitivity and favorable repeatability. Adopting embedded micro‑control technology, it features simple menu operation, complete functions and high reliability, with overall performance at a good domestic level.
It is applicable to combustible‑gas‑leakage emergency rescue, underground pipelines, mines and other sites, effectively protecting personnel safety and production equipment from damage. Its housing is made of high‑strength engineering plastics and composite elastic rubber materials, providing high mechanical strength and comfortable hand‑feel.
Above are the two common types of combustible gas detectors. You may refer to actual products to deepen your understanding.
