Für jede Anwendung die richtige Lösung [Translate]
Calibratable tube contact temperature measuring transducers with strap THERMASGARD® ALTM1 - Modbus - T3 with Modbus connection, housing made from impact-resistant plastic with quick-locking screws, with/ without optional display (for displaying actual temperature).
The surface contact sensor is used for temperature detection on piping, tubes (e.g. cold- 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 (zero point offset is adjustable).
