Description
Surface contacting temperature sensor
THERMASGARD® ALTM1 - Modbus - SD
Calibratable THERMASGARD ® ALTM1 - Modbus tube contact temperature measuring transducer with 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 temperature transmitter 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).
