Catalytic Combustible Gas Sensor MC112/C/D
Summary:
MC112/ MC112C/ MC112D adopts catalytic combustion principle, and its two arms of electric bridge consists of a test element and a compensate element. The resistance of the test element rises once it meets the combustible gases, in the same time, the output voltage of the bridge changes and the voltage variation rises in direct proportion to the gas concentration. The compensate element, as a conference, has the function of compensating temperature and humidity.
Feature:
* Bridge output voltage in linear
* Fast response & Long lifespan
* Good repeatability and selectivity
* Stable and reliable
* Resist H2S poisoning & organosilicone
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.
