Platinum RTD Flexible Averaging

(0)

The flexible averaging sensor measures across multiple points to produce a better duct air average than a single-point duct sensor.
The product uses a 1K ohm platinum RTD with Class A tolerance, DIN EN 60751 reference, and a 3850 ppm per deg C temperature coefficient.
The A/1K-2W-FA series is listed as two-wire and non-polarity-sensitive, with controller wiring connected to analog input leads.
The flexible sensor uses low-smoke PVC cable rated CL2P or CMP, with a 0.170 in nominal cable diameter and dual-wall adhesive heat shrink at sensing elements.
Ordering supports galvanized, plastic, aluminum bell box, and NEMA 4X enclosure options for different mounting and protection needs.
Flexible averaging is limited to 0 to 75 deg C operation, 10 to 90% non-condensing humidity, and applications that do not require UV, chemical, or high-humidity resistance.
Use the sensor across large air-handler duct sections where stratification makes a single-point reading less representative.
Use flexible averaging in rooftop HVAC ductwork when the operating temperature and humidity stay inside the flexible sensor limits.
Use a crisscross duct pattern to average mixed air streams and reduce error from hot and cold layers.
Place the averaging element downstream of fan discharge where the airstream is more uniform across the duct cross-section.
Use the sensor where return duct temperature needs a broad representative average instead of a local point sample.
Applications where averaged air temperature feedback can support tighter HVAC control.
