Description
Outside temperature / wet room temperature measuring transducer
THERMASGARD® ATM 2
Calibratable THERMASGARD® ATM 2 outside temperature measuring transducer with eight switchable measuring ranges, external sensor, continuous output, housing made of impact resistant plastic with quick-release screws, optionally with/without display, with cable gland or M12 connector according to DIN EN 61076-2-101.
The transmitter serves to detect outside temperatures, temperatures in wet rooms, and is installed e.g. on outside walls, in cold storage buildings and greenhouses, in the industrial sector and in agriculture. Installation in outdoor areas is preferably performed at the north side of a building or in a protected place. In cases of direct solar irradiation, we recommend the use of our WS 01 or WS 04 sun and ball-impact protection hood (accessory) or the device version with the installed SS 02 protection hood (on request).
