Outside temperature/ wet room temperature measuring transducers THERMASGARD® ATM 2 - Modbus - T3
Calibratable outside temperature measurement transducer THERMASGARD® ATM 2 - Modbus - T3, with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, optionally with/ without display, measures temperature (–50...+150 °C). International system of units SI (default) can be changed to imperial (via Modbus).

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 using our sun and ball-impact protection hood WS 01 or WS 04 (accessories).
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.
