ABSTRACT:
The speeds of two wheels are detected by means of wheel speed transducers associated with each wheel, each producing a DC voltage signal proportional to the respective wheel speed. The circuit includes two electric comparators, each having two inputs and one output, each output controlling a fault indicator in the form of an incandescent light. The two inputs for each comparator are the two produced DC voltage signals; and each comparator is identified with one transducer which provides a triggering wheel speed signal, with the other transducer providing a reference wheel speed signal. Sensitivity resistors provide a positive bias on the reference signal input to each comparator. Normally the two wheel speed signals are the same; however, when a triggering wheel speed signal increases a selected amount relative to the reference wheel speed signal, responsive to an underinflated tire, the associated comparator switches to activate the fault light to indicate an underinflated tire.
