THERMASGARD
Calibratable tube contact temperature measuring transducers THERMASGARD
internal or remote sensor, continuous output, strap and terminal box enclosure made of impact-resistant plastic, enclosure cover with quick-locking
screws, with or without optional display. This surface contact sensor is used for temperature detection on piping and tubes (e.g. cold-water and
hot-water), or on heating sections for heating system control. The tube sensors are factory-calibrated. Adjustment ⁄ fine adjustment by the user is
possible (range and zero point are adjustable).
