One general aspect includes a tethered temperature sensor (300) for use within a vehicle track (100). The tethered temperature sensor (300) includes one or more sensors (308) for measuring temperature located in a high strain and high temperature region (104) of the vehicle track (100). The sensor also includes circuitry (402) configured to control and/or monitor the one or more sensors and located in a low strain and low temperature region (102) of the vehicle track (100). The sensor also includes a housing (406) to contain the circuitry. The sensor also includes an encapsulating material (408) that fills an interior of the housing (406).
