Product introduction

  • 1. MR511 hot-wire gas sensor product description
  • MR511Hot-wire gas sensorIt operates on the principle that gas adsorption on the surface of a metal oxide semiconductor causes changes in thermal and electrical conductivity, with gas concentration determined by the resistance change of a platinum coil. The MR511 consists of a detection element and a compensation element forming two arms of a Wheatstone bridge. When flammable gas is present, the resistance of the detection element decreases, causing a change in the bridge output voltage, which increases proportionally with gas concentration. The compensation element serves as a reference and provides temperature compensation.
