THERMASGARD® ATM2-Modbus-T3 LCD

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).
