Condition monitoring system (tire pressure)

摘要: A monitoring system for the condition in a vehicle wheel mounted tire. The includes first and second LC circuits disposed within tire interconnected by diode multiplier series with pressure switch. An exciter establishes an energetic electromagnetic field of frequency such that circuit is resonant at same frequency. This converted into energy harmonic impressed upon which frequency, being either even or odd (exciting) receiver tuned to interrogates presence switch opens when falls below predetermined prevents activation so will not sense resonant, case there provided indication desired pressure. scanner scans successively from one another vehicle.
