What are the classifications of gas detectors? Pumping gas detector The pumping gas detector uses a built-in getter pump to quickly detect gas concentrations in the working environment. The pumping gas detector adopts imported sensor, has a very clear large liquid crystal display, and sound and light alarm prompts, ensuring that dangerous gases can be detected in a very unfavorable working environment and promptly prompting the operator to prevent. Diffusion gas detector The portable gas leak detector continuously detects the gas concentration in the working environment. The gas leak detector detects the gas concentration by natural diffusion method, adopts imported sensor, has excellent sensitivity and excellent repeatability; the gas detector adopts embedded micro-control technology, the menu operation is simple, the function is complete, the reliability is high, the whole machine performance Leading domestic level. The detector shell is made of high-strength engineering materials and composite elastic rubber material, which has high strength and good hand feeling. Online gas detection alarm The online gas detection alarm is composed of a gas detection alarm controller and a fixed gas detector. The gas detection alarm controller can be placed in the duty room to monitor and control each monitoring point. The gas detector is installed at the most leaking place of the gas. The core component is a gas sensor. The gas detector converts the gas concentration detected by the sensor into an electrical signal and transmits it to the gas detection 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 gas detection alarm controller sends out an alarm signal, and can activate an external device such as a solenoid valve and an exhaust fan to automatically eliminate hidden dangers. The online gas detection alarm is widely used in petroleum, chemical, metallurgy, electric power, coal mines, water plants and other environments to effectively prevent explosion accidents.
