Siemens Combustion QRA10M.C Sensor R-22 the DATS (Discharge Air TemperatureThe Siemens Combustion QRA10M. C Sensor is a high sensitivity UV flame detector designed for the intermittent supervision of gas and oil flames, as well as ignition spark proving. Engineered for industrial burner controls, this sensor features a spectral sensitivity range of 190 to 270 nm, ensuring it reacts only to the ultraviolet radiation of the flame and remains blind to glowing firebrick or ambient lighting. The high sensitivity UV cell is housed
