Product description
- Measuring range: – 50...+ 150 °C / – 58...+ 302 °F
- Output: Modbus
- Protection type: IP 65
International system of units SI (default) can be changed to imperial (via Modbus).
The pipe surface-contact sensor is used to detect the temperature on lines, pipes (e.g., cold and warm water) or on heating sections for heating control.
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.
