Siemens Combustion QRA4M.U Scanner Els PW 17895 The ceramic insulator is builtThe Siemens Combustion QRA4M. U is a high sensitivity UV flame scanner engineered for the rigorous supervision of gas or oil flames and ignition spark proving in intermittent burner operations. As a veteran grade flame detector, this sensor utilizes a specialized UV sensitive cell with two electrodes designed to ignite upon detecting radiation within the 190 to 270 nm spectral range. This ignition triggers the necessary current in the flame detector
