Für jede Anwendung die richtige Lösung [Translate]
Calibratable outside temperature measuring transducers THERMASGARD® ATM 2 - Modbus - T3 with Modbus connection, housing made from impact-resistant plastic with quick-locking screws, with/ without optional display (for displaying actual temperature).
For the detection of outside temperatures, temperatures in wet rooms, e.g. for installation in outside walls, in cold storage buildings and greenhouses, in the industrial sector and in agriculture. Installation of the temperature transmitter in outside areas preferably at the north side of the building or in a protected place.
In cases of direct solar irradiation, we recommend the use of our WS 01 or WS 04 sun protection hood (accessory).
The outdoors sensors are factory-calibrated. Adjustment/ fine adjustment by the user is possible (zero point offset is adjustable).
