摘要 |
An apparatus for detecting a pressure drop in a tire chamber of a tire-and-wheel assembly for an automotive vehicle, comprising an oscillator assembly held stationary with respect to the vehicle body structure and a resonator assembly mounted on the wheel rim of the tire-and-wheel assembly, wherein the resonator assembly comprises a resonant inductor and a resonant capacitor which are electrically connected together across a pressure-sensitive switch unit directly communicating with the tire chamber and which are positioned together with a portion of the switch unit within a protective receptacle secured to the wheel rim and wherein the resonant inductor and capacitor and the portion of the switch unit are encapsulated in a body of potting compound forming a potted resonance circuit structure within the protective receptacle, the switch unit and the resonant capacitor being positioned intermally of the resonant inductor.
