Air Temperature Sensor

Last update: 15 Jan. 2024

What is an Air Temperature Sensor?

The Air Temperature Sensor or the Air Intake Temperature Sensor determines the temperature of the outside air entering the engine.

Internal Combustion Engine (ICE) behaviour is key to ensure the best efficiency in all conditions.

Our compact temperature sensor ensures the control of the thermal engine behaviour and especially the air loop (from the intake up to the EGR loop). With good accuracy we are able to ensure engine management, diagnostics and thermal protection.
