What is the accuracy of your temperature sensors?

Our automotive NTC temperature sensors provide ±3°C precision accuracy across the operating range, suitable for coolant, EGR, HVAC and EV battery thermal management.

What temperature range do your sensors support?

Our temperature sensors operate reliably from -40°C to +150°C, covering all automotive applications from cold climate starts to high-temperature engine compartments.

Can you supply custom NTC Rt curves?

Yes. We supply NTC thermistors with custom resistance-temperature (Rt) curves matched to your ECU or BMS reference table, in plastic, aluminium, brass and stainless-steel housings.

Do you offer on/off thermostat switches as well?

Yes. Snap-action SPST/SPDT thermostat switches are supplied separately for fan switching and over-temperature cut-out. See our Temperature Switches page.

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.
