THERMASGARD ®
Calibrateable tube contact temperature measuring transducers THERMASGARD
or remote sensor, continuous output, strap and terminal box enclosure made of impact­resistant plastic, enclosure cover with quick­locking
screws, optional with or without display. This surface contact feeler is used for temperature detection on piping and tubes (e.g. coldwater
and hot­water), or on heating sections for heating system control. The tube sensors are factory­calibrated. Adjustment ⁄ fine adjustment by
the user is possible (range and zero point are adjustable).
