Sleeve sensor with temperature measuring transducer THERMASGARD® HFTM - Modbus - T3
Calibratable THERMASGARD® HFTM - Modbus - T3 sleeve temperature measuring transducer with Modbus connection, in an impact resistant plastic housing with quick-locking screws, optionally with/without display, cable sensor with stainless steel sleeve.

The sleeve sensor device serves to detect the temperature in liquid and gaseous media. It is used as a duct sensor or, if installed in a THE thermowell (accessories), as an immersion and screw-in sensor in liquids.
Innovative Modbus sensor with galvanically separated RS485 interface, selectable bus termination resistance, DIP switches for setting the bus parametres and bus address in currentfree state, LEDs for telegram status display, two separate push-in terminals and a large back-lit three-line display with customised programming in the 7-segment range and dot-matrix ranges. The transmitter uses internal diagnostics to detect sensor breakage or shorts as errors. The error messages can be retrieved via Modbus and are shown on the display. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
