ACI A/CP-RA-12"-GD : Rigid Probe Averaging Temperature Sensor, 10K Type II Thermistor, 12" Probe, Galvanized Enclosure
Applications:
- Air Handlers
- Roof Top Units
- Mixed Air / Discharge /Supply Air Temperature Monitoring
- Data Centers
- Hospitals
The ACI Thermistor Rigid Averaging Series boasts a 1⁄4” Diameter stainless steel sensing element, equipped with two 12-inch 22 AWG Etched Teflon colored lead wires for easy sensor type differentiation. Featuring 4 sensing points in lengths ranging from 12” to 48”, these sensors offer superior average temperature measurement within ducts compared to single point sensors. Hermetically sealed to prevent moisture intrusion, each sensor includes an integrated foam pad for effective duct sealing and vibration dampening upon installation. Mountable like standard single point duct sensors, the rigid averaging sensor stands out with three additional sensing points for enhanced control.
