Tethered temperature sensor for use in rubber embedded applications
One general aspect includes a tethered temperature sensor for use within a vehicle track. The tethered temperature sensor includes one or more sensors for measuring temperature located in a high strain and high temperature region of the vehicle track. The sensor also includes circuitry configured to control and/or monitor the one or more sensors and located in a low strain and low temperature region of the vehicle track. The sensor also includes a housing to contain the circuitry. The sensor also includes an encapsulating material that fills an interior of the housing.
