THERMASGARD ®
Calibrateable temperature measuring transducer with sleeve sensor THERMASGARD
output, optional with or without display (displaying the actual temperature), terminal box enclosure made of impact-resistant plastic and enclosure
cover with quick-locking screws. The THERMASGARD
liquid and gaseous media, e.g. by installation inside an immersion sleeve, or as duct sensor. The sensors are factory-calibrated. Adjustment ⁄ fine
adjustment by the user is possible (zero point offset is adjustable).
