MP-2 smoke gas sensor adopts multi-layer thick film manufacturing process, and heater and metal oxide semiconductor gas sensitive layer are made on both sides of micro Al2O3 ceramic substrate, and packaged in metal shell. When there is a gas in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. A simple circuit can be used to convert this conductivity change into an output signal corresponding to the gas concentration.
Sensor Features
This product has good sensitivity to propane, smoke, etc. in a wide concentration range, and has the characteristics of small size, long life, low cost, and simple driving circuit.
Main Applications
Widely used in household smoke alarms, industrial smoke alarms and portable smoke instruments.
MP-4 Combustible Gas Sensor
Product Description
MP-4 Combustible Gas Sensor adopts multi-layer thick film manufacturing process, and heater and metal oxide semiconductor gas sensitive layer are made on both sides of micro Al2O3 ceramic substrate, and packaged in metal shell. When there is a gas 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 conductivity change can be converted into an output signal corresponding to the gas concentration using a simple circuit.
Sensor Features
This product has good sensitivity to methane in a wide concentration range, and has the advantages of strong anti-interference ability, low power consumption, fast response recovery, good stability, long life, low cost, and simple driving circuit.
Main Applications
1. Combustible gas leak monitoring devices for homes, factories, and commercial uses, fire prevention/detection systems.
2. Combustible gas leak alarms, gas leak detectors.
MP135/MP503 Air Quality Gas Sensor
Product Description
The MP135/MP503 air quality gas sensor adopts a multi-layer thick film manufacturing process, and a heater and a metal oxide semiconductor gas-sensitive layer are made on both sides of the micro Al2O3 ceramic substrate, which are encapsulated in a metal shell. When the gas is present 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.
Sensor Features
This product is highly sensitive to alcohol, smoke, isobutane, and formaldehyde; it has the advantages of fast response recovery, low power consumption, simple circuit, good stability, and long life.
Main Applications
Used in home environments and office harmful gases, automatic exhaust devices,
air purifiers, etc.
