This 5-foot negative temperature coefficient sensor is engineered for high-accuracy resistance-to-temperature conversion

while also supporting PWM (Pulse Width Modulation) at 1500 Ohm

it delivers high-density thermal output typically used in 4 and 5-ton air handlers

it is fully compatible with R-134A and other non-corrosive HFCs used in modern commercial systems

This replacement part ensures your system maintains the exact CFM specifications required for optimal refrigerant evaporation and prevents premature heat exchanger fatigue

Dwyer Instruments PAFS-1005 Sensor 321702-401 This 5-foot negative temperature coefficientThe Dwyer Instruments PAFS 1005 is a high performance averaging flow sensor engineered for contractors requiring precision in air and compatible gas measurement. Featuring a 9 29 32 inch insertion length, this pitot style flow probe utilizes multiple sensing ports to provide an accurate averaged velocity pressure signal, effectively managing the turbulence often encountered in short duct runs. Designed for seamless integration with differential
