ATM2 - VA ID
Rev. ID20 - V12 (+U)
Calibratable outside temperature measuring transducer
THERMASGARD
®
ATM 2 - VA
with eight switchable measuring ranges, external sensor,
continuous output, housing made from stainless steel V4A, with cable gland or M12 connector according to DIN EN 61076-2-101. It is used 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. Installation in outdoor areas preferably at the north side of a building 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 03
(accessories). The sensor is factory-calibrated;
an environmental precision adjustment by an expert is possible.
