Description
Sleeve temperature measuring transducer
THERMASGARD® HFTM - Modbus - SD
Calibratable THERMASGARD® HFTM - Modbus temperature measuring transducer with sleeve sensor, 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 temperature transmitter with remote sensor serves to detect temperatures in liquid and gaseous media e.g. if installed in a thermowell or as a duct sensor. The device is factory-calibrated. Adjustment/Fine-tuning by the user is possible (zero-point offset is adjustable).
