Control Resources Inc. offers a variety of temperature sensors ( thermistors ) compatible with the SmartFan® line of fan and motor controllers. The P-series ( 20KΩ at 25°C ) sensors have been the backbone of our sensor offerings for many years. The S-series ( 10KΩ at 25°C ), our new line of sensors, is generally more economical and has a tighter tolerance than its P-series counterpart. All Navigator™ programmable controllers can be programmed by the customer to use P-series or S-series sensors. Designs that are not Navigator compatible must use the P-series sensors only. Contact Control Resources Inc. prior to connecting thermistors from other sources to verify functionality.
