Outside temperature sensor THERMASGARD® ATM 2 - Modbus - SD

Calibratable THERMASGARD® ATM 2 - Modbus outside temperature measuring transducer with internal or external sensor, Modbus connection, terminal box housing made of impact resistant plastic, housing cover with quick-locking screws, with/without optional display for indicating the actual temperature.

The temperature transmitter serves to detect outside temperatures, temperatures in wet rooms e.g. for installation on outside walls, in cold storage buildings and greenhouses, in the industrial sector and in agriculture. In outdoor areas, the device should preferably be installed at the north side of a building or in a protected place. In cases of direct solar irradiation, a WS 01 or WS 04 sun and ball protection hood (accessories) or the device version with installed SS 02sunshade (available on request) must be used. The outdoor sensor device is factory-calibrated. Adjustment/Fine-tuning by the user is possible (zero-point offset is adjustable).
