Suited for shaded outdoor air monitoring, this outside air temperature sensor reads -22 to 158°F (-40 to 70°C) from a weatherproof Euro housing with a twist-off cover. In addition, a 3 kΩ NTC thermistor sits behind a downward-facing tube that keeps water and ice out. It suits economizer control, cold storage and condensing environments.

The ACI Thermistor Outside Air Series features a weather proof European Style Plastic enclosure with twist off cover and water tight cord grip fitting. The sensing element contains two, 14" 22 AWG Etched Teflon colored lead wires to differentiate the many different sensor types.
All sensors in this series are manufactured using ACI’s proven double encapsulation process to eliminate the effects of moisture upon the sensors as well as to increase the thermal response time using our high quality, thermally conductive epoxy. The outside air sensor is a single point sensor designed to be mounted under an eave or on the North side of a building in a shaded location. The sensing tube pointed must be pointed downward to prevent any water or ice from settling in the sensing tube.
Optional NEMA 4X “-4X” or NEMA 3R rated “-BB” cast Aluminum enclosure and NIST Certificates are available as specified in the ordering grid on the back of the product data sheet. For Applications in which the sensor must be mounted in direct sunlight, please see the Sun Shield data sheet which will allow you to order a Temperature or Temperature/Humidity Combination sensor.
