MC112/MC112C/MC112D Catalytic Flammable Gas Sensor
|Target:||Combustible gases such as industrial natural gas,LPG, coal gas and alkanes|
|Detection range:||0-100%LEL(Anti-explosion Mark：ExdibⅠ)|
|Detection principle:||catalytic combustion|
|Characteristics:||Bridge output voltage in linear, fast response, good repeatability and selectivity|
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.
It is widely used in industrial occasion to detect the concentration of natural gas,LPG, coal gas and alkanes.
It is also used in combustible gas leakage alarm system, combustible gas detector and gas concentration meter and so on.
It has good sensitivity to methane in wide range, and has advantages such as long lifespan, low cost and simple drive circuit, etc. The bridge output is linear, quick response, good repeatability and selectivity, good stability, excellent resistance to the interference of H2S gas and organosilicone.

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with UL, CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to firstname.lastname@example.org
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
