Q1: What is a fixed gas detector?
A1: The fixed gas detector is composed of sensors and transmitters, and is installed at the detection site. The secondary instrument consisting of circuit, power supply and display and alarm device is installed in a safe place, which is convenient for staff to monitor. In industrial installations and production processes, fixed gas detectors are generally used, because fixed gas detectors can be installed at specific detection points to detect specific gas leaks.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: Difference between fixed gas detector and portable gas detector
A3: The biggest advantage of fixed gas detectors is 24-hour uninterrupted measurement. As long as the power is turned on, the fixed gas detector is in normal detection work. Portable gas detectors are usually used in confined spaces and confined spaces, but the gas environment in these spaces is usually very complex, and there will be situations such as lack of oxygen and high concentrations of harmful gases.
Tips: Gas detector working principle
The working principle of the gas detector is to use the electrochemical principle to detect a certain amount of gas. After the sensor is sintered, it enters the sensor through the breathable membrane on the sensor. The sensor electrodes and electrolyte consume oxygen, creating an electrical current between the anode and cathode. When current is passed through the inductor, the positive electrode of lead is oxidized to lead oxide, and the output current intensity is linearly related to the oxygen concentration. The sensor's fast response capability enables continuous monitoring of air or process gases.
If you don't know where the leak is, use this gas detector to find the leak. As far as the structure is concerned, it is a product used for the separation of the head detection probe, which can be used as a handheld mobile detection or online desktop detection, suitable for some specific places.
