ASTF NTC 20k Space radiation temperature sensor

Resistance thermometer THERMASGARD~ ASTF with passive output. Housing made of plastic with quick release screws. The sensor was specially developed as a black bulb sensor for measurement in larger rooms and halls. Due to the measuring method used and through correct positioning in the room, a representative temperature display is achieved. The ASTF determines the effective working radiant part or the effective radiant heat at the measurement site. Taking into account the radiant heat and the thermal comfort (sensation temperature), the global temperature is determined. The feeling temperature is an interplay of thermal radiation and thermal convection (the globetemperature relates to the air temperature approx. 70 % to 30 %).
