Brand Name: Winsen

High-concerned chemical: none

Material: Mixture

Origin: Mainland China

Type: Gas Sensor

Use: Gas Sensor

MR007 gas sensor consists of a test element and a compensation element. The resistance of the test element changes with the variation of electrical and thermal conductivity caused by the adsorption of flammable gas on the surface of the sensitive material, thereby measuring the gas concentration. The MR007 detection circuit adopts a Wheatstone bridge, which consists of a pair of detection elements and compensation elements as one arm of the bridge. When encountering flammable gas, the resistance of the detection element decreases, and the output voltage of the bridge changes. This voltage change increases with the increase of gas concentration. The compensation element serves as a reference and temperature compensation.

Application

Suitable for combustible gas detection including Natural gas, LPG, and coal gas, etc.

Features

MR007 gas sensor has advantages of good linearity, fast response , excellent repeatability, stable and reliable operation of the components, and good resistance to hydrogen sulfide and silicone interference.
