Flat Semiconductor Combustible Gas Sensor MP-2
Summary:
MP-2 model with advanced planar construction is comprised of heater and metal oxide semiconductor material of subminiature Al2O3 ceramic plate, fetch out electrode down-lead, encapsulation in metal base and cap. When the target gas exists , the sensor's conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, convert change of conductivity to correspond output signal of gas concentration.
Feature:
* Good sensitivity to LPG, smoke in wide range
* Small size
* Long lifespan
* Low cost
* Simple circuit
APPLICATION
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.
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.
