Automotive-Grade NTC Thermistor Sensors

Precision Temperature Sensing for Modern Vehicles

Our Automotive NTC Thermistor Sensors are engineered for high reliability, precision, and durability in the most demanding automotive environments. Whether it’s monitoring engine coolant temperature, air intake temperature, battery packs, or cabin climate control, our sensors deliver fast response and accurate measurements across a broad temperature range.

Applications of NTC Thermistors in Automobiles

Application AreaPurpose
Engine Coolant Temperature (ECT) SensorMonitors engine temperature for ECU adjustments.
Intake Air Temperature (IAT) SensorMeasures air temperature entering the engine for fuel-air mixture control.
Cabin Climate Control SensorsMaintains desired cabin temperature (HVAC systems).
Battery Temperature SensorsMonitors EV/Hybrid vehicle battery temperature to prevent overheating.
Transmission Fluid Temperature SensorsEnsures optimal transmission performance and longevity.
Exhaust Gas Recirculation (EGR) SensorsRegulates emissions by sensing exhaust temperatures.
