Summary:

MP402 combustible gas sensor adopts multi-layer thick film manufacturing technology. The heater and metal oxide semiconductor gas sensitive layer are made on both sides of the micro Al2O3 ceramic substrate, which are packaged in the metal shell. When the detected gas exists in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. This change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit.

Feature:

This product has good sensitivity to methane in a wide concentration range, and has the advantages of excellent anti-interference ability, low power consumption, fast response recovery, good stability, long life, low cost, and simple driving circuit.

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.

Other Detector

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.

Home Combustible Gas Alarm

The combustible gas alarm is an alarm device for detecting gas leakage. The component that reacts to the combustible gas is a gas sensor, and the response signal is converted into an electrical signal through the circuit board. When the combustible gas in the air reaches a certain concentration value, the alarm will alarm. The high-end household combustible gas alarm can automatically start the exhaust equipment and close the gas pipeline valve at the same time. A wireless transmission device can be installed inside the gas alarm to realize overall monitoring and network alarm to ensure the safety of everyone's life and property.
