HFTM Rev. 2017 - V12 GB
Calibratable temperature measuring transducer with sleeve sensor THERMASGARD
®
HFTM with eight switchable measuring ranges, continuous
output, with or without optional display (displaying the actual temperature), terminal box enclosure made of impact-resistant plastic and enclosure
cover with quick-locking screws. The temperature transmitter with remote sensor is used for temperature detection in 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). Direct and permanent use in liquids is possible in combination with THE immersion sleeves.
