OUTSIDE AIR
Weatherproof Outside Air, Thermistors
The ACI Thermistor Outside Air Series features a weather proof European Style Plastic enclosure
with twist o cover and water tight cord grip tting. The sensing element contains two, 14 inch
22 AWG Etched Teon colored lead wires to dierentiate the many dierent sensor types. All
sensors in this series are manufactured using ACI’s proven double encapsulation process to
eliminate the eects 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 Certicates are available as specied 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.
Applications: Outside Air Temperature Sensing, Cold Storage Facilities, High Dew Point/Condensing Environments
