Catalytic Combustible Gas Sensor MC116
Summary:
MC116 type catalytic combustion gas sensor works according to the principle of catalytic combustion effect. The detection element and the compensation element are paired to form an arm of the bridge. When the flammable gas is encountered, the resistance of the detection element increases, and the output voltage of the bridge circuit changes. It increases proportionally with the increase of gas concentration, and the compensation element acts as a reference and compensation for temperature and humidity.
Feature:
The output voltage of the bridge circuit is linear, the response speed is fast, the repeatability and selectivity are good, the work is stable and reliable, and the resistance to hydrogen sulfide and silicone interference is good.
APPLICATION
Industrial Combustible Gas Alarm
In the process of industrial use of combustible gas, if the combustible gas is in an incomplete combustion state or has gas leakage, etc., the combustible gas will cause personnel poisoning or fire accidents, directly threatening the life safety of personnel. Therefore, it is necessary to install an industrial-grade gas alarm. If the gas exceeds the standard in the on-site environment, the alarm can give an early warning, thereby reducing the probability of danger.
Coal Mining Industry Poison Gas Monitoring
Flammable gas is mainly detected by catalytic sensor, mainly measuring 100% LEL, and also using thermal conductivity components to measure 100% VOL. High-end gas detection products in the petrochemical industry are gradually using infrared gas sensors, which can measure 100% LEL and 100% VOL. At the same time, laser beam technology is also gradually being used in the petrochemical industry.
Petrochemical Industry Toxic Gas Monitoring
The energy provided by the petrochemical industry is mainly used as fuel for automobiles, tractors, airplanes, ships and boilers. At the same time, refinery enterprises provide various chemical raw materials for the chemical industry, and flammable gas also enters thousands of households.
Formaldehyde detector is an instrument for detecting formaldehyde. Generally, semiconductor sensors and electrochemical sensors are used to realize the rapid semi-quantification of formaldehyde in indoor air on the spot, which is characterized by simple structure, small size, intuitive,easy to carry and use.
Gas safety detection through the whole process of mine production, processing and transportation, such as the detection of mashgas(methane), carbon monoxide (CO), hydrogen sulfide (H2S), carbon dioxide (CO2), sulfur dioxide (SO2), oxygen (O2), etc.
