Surface contacting temperature sensor THERMASGARD® ALTM 2 - Modbus
Calibratable THERMASGARD ® ALTM 2 - Modbus tube contact temperature measuring transducer with detached sensor and strap, Modbus connection, terminal box housing made of impact resistant plastic, housing cover with quick-locking screws, with/without optional display for indicating the actual temperature.
The surface-contact sensor is used for temperature detection on lines, pipes (e.g. cold and hot water) or on heating sections for heating system control. The tube sensor is factory-calibrated. Adjustment/Fine-tuning by the user is possible (zero-point offset is adjustable).
