PROBE ONLY

Stainless Steel Probe, Thermistor

The ACI Thermistor Probe Only Series features a ¼” diameter stainless steel probe with two, 14”
or 24 inch 22 AWG Etched Teon colored lead wires to dierentiate the dierent NTC sensor
types. The sensors in this series are manufactured using ACI’s proven double encapsulation
process to eliminate the eects of moisture upon the sensors and to increase the thermal
response time using our high quality, thermally conductive epoxy. The probe is designed to be
used in duct and immersion applications when used with the proper length thermowell.

Applications: Roof Top Units, Air Handlers, Supply/Discharge Air/Return/Mixed/Exhaust Air
Duct Temperature Sensing, Immersion Temperature Sensors, Replacement Temperature Sensors
