ATM 2 Rev. 2017 - V12 GB
Calibratable outside temperature measuring transducer THERMASGARD
®
ATM 2 with eight switchable measuring ranges, internal or remote
sensor, continuous output, terminal box enclosure made of impact-resistant plastic, enclosure cover with quick-locking screws, with or without
optional display. For the detection of outside temperatures, temperatures in wet room areas, e.g. for installation on outside walls, in cold storage
buildings and greenhouses, in the industrial sector and in agriculture. Installation in outdoor areas preferably at the north side of a building or in a
protected place. In case of direct sun irradiation, the sunshade and ball game protection
WS 01 (accessories) or the device variant with the installed
sunshade
SS 02 (available on request) must be used. These outdoor sensors are factory-calibrated. Adjustment ⁄ fine adjustment by the user is
possible (zero point offset is adjustable).
