Product description
- Measuring range: – 50...+ 150 °C / – 58...+ 302 °F
- Output: Modbus
- Protection type: IP 65
The on-wall sensor is used to detect the temperature in gaseous media. It is used outside or in wet rooms, in cold storage buildings and greenhouses, in the industrial sector and in agriculture.
Installation on outside walls is preferably performed on the north side or in a protected place. In case of direct solar irradiation, we recommend the use of our sun and ball-impact protection hood WS 01 or WS 04 (accessories) or the device version with the installed sun protection SS 02 (on request).
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.
