Frequently Asked Questions

Engineering answers to the questions our customers ask most often.

An automotive temperature sensor converts thermal energy into a resistance or voltage signal for the ECU or instrument cluster. NTC thermistors (negative temperature coefficient) are most common — resistance falls as temperature rises, providing high sensitivity at low cost. Sensing Technologies manufactures NTC thermistors and snap-action temperature switches rated ±3°C accuracy across –40°C to +150°C with IP67 protection for radiator, EGR, HVAC, coolant and EV battery thermal management.
