ACI A/AN-FA-24'-4X : Flexible Cable Averaging Temperature Sensor, 10K Type III Thermistor, 24' Probe, NEMA 4X Enclosure
Applications:
- Air Handlers
- Roof Top Units
- Mixed Air / Discharge /Supply Air Temperature Monitoring
- Data Centers
- Hospitals
The ACI Thermistor Flexible Averaging Series features an 18 AWG Plenum Rated cable sensing element with two, 12 inch 22 AWG Etched Teflon colored lead wires to differentiate the different sensor types. The sensors in this series are multi-point. Averaging sensors provide a better overall average temperature of the actual air inside larger ducts when compared to that of a single point sensor. All flexible averaging sensors are limited to being used in applications where operating temperatures are limited and high humidity, chemical resistance, and UV light sources aren’t required. Each of the sensing elements is protected using a dual wall adhesive lined heat shrink tubing to provide a basic level of moisture protection. The sensor length should be determined by the size of your duct.
