Product description
- Measuring range: – 50...+ 150 °C / – 58...+ 302 °F
- Inserted Length: 100 mm
- Output: Modbus
- Protection type: IP 67
Calibratable temperature measuring transducer with sensor tube THERMASGARD® TM65-Modbus-SD 100mm LCD, with Modbus connection (Y-adapter), in an impact-resistant plastic housing with quick-locking screws, stainless steel-protective tube (100 mm), with display, measures temperature (–50...+150 °C / – 58...+ 302 °F). International system of units SI (default) can be changed to imperial (via Modbus).
The duct sensor is used to detect the temperature in liquid or gaseous media. Use the stainless steel immersion sleeves for aggressive media. It is used in heating engineering, ventilation and air conditioning ducts, pipes, storage systems, compact district heating stations, warm and cold water systems, oil and lubrication cycle systems, machine and systems engineering and the entire industry sector.
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.
