Temperature Sensors for E-Vehicles

Our range of surface temperature sensors are a versatile lot and are used across a number of different industries. Some of our more interesting projects include those within the e-vehicle and medical device markets, where they are also used as temperature compensation devices.

These e-vehicle battery sensors need to be small, accurate, robust and fast responding, and our wide range of surface temperature sensors cover all these key parameters and more.
