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.
