Gas Detector Selection According to Target Detection Gases
Regarding the knowledge introduction of combustible gas detectors, in order to facilitate everyone's understanding, we can start with the common types in daily life. Below, we will introduce the two common types of combustible gas detectors.
Fixed installation combustible gas detector
The online combustible gas detection alarm mainly consists of a gas detection alarm controller and a fixed combustible gas detector. The gas detection alarm controller can be placed in the duty room and mainly controls various monitoring points. The combustible gas detector is installed in the most vulnerable gas leakage point, and its core component is the built-in gas sensor.
The combustible gas detector converts the concentration of combustible gas detected by the sensor into an electrical signal, which is transmitted to the alarm controller through a cable. The higher the gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the alarm controller, the alarm sends an alarm signal and can activate external devices such as solenoid valves and exhaust fans to automatically eliminate hidden dangers.
Portable combustible gas detector
The portable combustible gas detector detects gas concentration through natural diffusion and uses a catalytic combustion sensor with excellent sensitivity and repeatability; The combustible gas detector adopts embedded microcontroller technology, with simple menu operation, complete functions, high reliability, and overall performance ranking among the best in China.
It is suitable for emergency response to combustible gas leaks, underground pipelines or mines, etc., and can effectively ensure the safety of workers and prevent damage to production equipment. The shell of the portable gas meter is made of high-strength engineering materials and refined composite elastic rubber materials, with high strength and good hand feel.
The above are two common types of combustible gas detectors. You can learn about the physical products of these two types to deepen your understanding.
