Description
Duct/ smoke gas temperature measuring transducer
THERMASGARD® RGTM 1
Calibratable THERMASGARD® RGTM 1 flue gas measuring transducer with eight switchable measuring ranges, exchangeable spring-mounted measuring insert, straight protective tube, connecting head made of aluminium, metal mounting flange and continuous output for the detection of high temperatures in gaseous media, e.g. for exhaust air or flue gas temperature measuring.
The sensor device is are factory-calibrated. Adjustment/Fine-tuning by the user is possible (range and zero-point are adjustable).
