Description

Sleeve sensor with temperature measuring transducer THERMASGARD® HFTM - Modbus - T3
Calibratable sleeve temperature measuring transducer THERMASGARD® HFTM - Modbus - T3, with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, cable sensor with a stainless steel sleeve, optionally with/ without display, measures temperature (–50...+150 °C). International system of units SI (default) can be changed to imperial (via Modbus).

The sleeve sensor is used to detect the temperature in liquid and gaseous media. It is used as a duct sensor or, if installed in immersion sleeve THE (accessories), as an immersion and screw-in sensor in liquids.
Innovative Modbus sensor with galvanically separated RS485 Modbus interface, selectable bus termination resistance, DIP switch for setting the bus parameters and bus address in current-free state, internal LEDs for telegram status display, two separate push-in terminals and large three-line display (illuminated, with customised programming in the 7-segment range and dot-matrix range). Uses internal diagnostics to detect sensor breakage or sensor short circuit as errors. The error messages can be retrieved via Modbus and are shown on the display. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
