Description
On-wall radiation temperature sensor
THERMASGARD® ASTF
THERMASGARD® ASTF resistance thermometre with passive output, terminal box housing made of impact resistant plastic and housing cover with quick-locking screws. The radiation sensor device is specifically designed for temperature detection in wet areas or in larger rooms/halls.
The on-wall radiation temperature transducer determines the effective portion of active radiation or the effective radiant heat at the measured location. Excellent measuring results, representative of the specific room, are achieved thanks to the measuring method employed by the dark radiation sensor.
