Description produit

The thermocouple has been developed for the use with different pilot burners. As long as the pilot flame heats the tip of the thermocouple, a low DC voltage is generated which supplies the coil of the safety pilot and keeps the safety valve open. If in case of a failure the pilot flame goes out, no voltage is generated any more and the safety pilot interrupts the gas supply to the burner.Technical data:- DC voltage: 22...30 mV- max. drop-out time: 30 or 45 s (depending on the order number)- max. operating temperature: hot junction: 750° C / cold junction: 415° C- recommended operating temperature: hot junction: 650° C +/- 50° C
