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 traditional automotive applications, where they are used as temperature measurement devices. These include those funded by Innovate UK under the Faraday Battery Challenge, where we are supporting R&D by both companies and academics.

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.

Our range includes :

    • Ring Terminal Sensors – available in various forms. They are neat combining integral electrical solutions as well as thermal isolation to minimise heat-loss away from the sensor.
    • Flexible Film Sensors – available in various forms, and thicknesses. They are robust and can be supplied in various lengths ensuring that the sensing element is directly where you need it – even in tight spots.
    • SMD NTC’s – our SM range of automotive grade of SMD NTCs cna be added to the same circuit to offer local temperature sensing.
    • NEW – We now can supply a high voltage sensor capable of withstanding 1000 VDC.
