Abstract

The motor vehicle wheel temp. monitor circuit consists of two temp.-dependent sensors fitting diametrically opposite each other to the inside wall of the wheel rim, with a pick- up device in near proximity to the rotating sensors fitted to the vehicle chassis. Each sensor comprises a cylindrical housing (22) screwed into the wheel rim with a sealing gland ensuring an air-tight fit (21). A heat-insulating sleeve isolates the cylinder from the wheel rim. A permanent magnet (26) is positioned at the inner end of the central boring of the cylinder and butts onto a rod of temperature-sensitive magnetic material (27). Temperature variation within the tyre chamber causes a change in the magnetic flux induced into the pick-up coil (14) and the resulting signal is amplified to operate a calibrated indicator (61). An integration and comparator circuit (15) provides an output related to a selected nominal temp. for safe working.
