ABSTRACT:
A failsafe feedback control system of the type including transducers for measuring a characteristic of some object and emitting a signal representative of such measurement to a controlled apparatus the operation of which is responsive to such signal. The apparatus includes a first switch for detecting when any two transducers have failed and a second switch for detecting when any one transducer has failed. The responsiveness of the circuitry of each transducer can be set independent of that of all of the other transducers.
