Description

The Siemens QRA2M(1) flame sensor is designed to equip the ignition and control system of a gas or oil burner. It registers the ultraviolet radiation of the flame during fuel combustion. It connects to automation to transmit electrical signals about the presence/absence of a flame. 

Features and parameters:

  • device with side and frontal measurement;
  • response to UV radiation;
  • for burners with intermittent operation;
  • high spectral sensitivity;
  • metalized plastic housing to protect the sensitive element;
  • operation at temperatures from -20...+60 degrees;
  • dust and moisture protection level – IP 40;
  • insensitivity to light from fireclay bricks, lamp lighting, etc.;
  • for use with Siemens burner controllers. 

The UV element of the Siemens QRA2M(1) flame sensor has a service life of 10,000 operating hours (approximately 1 year) when observing the operating temperatures (no higher than +50 °C). Exceeding the recommended temperatures will significantly reduce the sensor's service life.
