Sleeve temperature measuring transducer THERMASGARD® HFTM - Modbus - SD

Calibratable sleeve temperature measuring transducer THERMASGARD® HFTM - Modbus-SD, with Modbus connection (Y-adapter), in an impact-resistant plastic housing with quick-locking screws, cable sensor with a stainless steel sleeve, ptionally with/ without display, measures temperature (–50...+150 °C).

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. Modbus sensor SD with RS485 Modbus interface (not galvanically isolated), selectable bus termination resistance, DIP switch for setting the bus parameters and bus address in current-free state, internal LEDs for telegram status display (illuminated, with customised programming). Uses internal diagnostics to detect sensor breakage or sensor short circuit as errors. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
