TL;DR: In this paper, the authors describe the preferred embodiments as including an Input CIRCUIT for separating AC and DC components of a signal, and a CIRUIT for constraining the AC component and translating it to DC component.
Abstract: MONITORING APPARATUS SHOWN IN A PREFERRED EMBODIMENT AS INCLUDING AN INPUT CIRCUIT FOR SEPARATING AC AND DC COMPONENTS OF A SIGNAL, A CIRCUIT FOR CONDITIONING THE AC COMPONENT AND TRANSLATING IT TO DC OUTPUT SIGNAL WHICH IS PROPORTIONAL TO THE PEAK-TO-PEAK VALUE OF THE AC COMPONENT, AND VARIOUS READOUT MEANS. MEANS FOR CALIBRATING THE CIRCUIT AND READOUTS, AND MEANS FOR LIMITING TRANSIENT EFFECTS ARE ALSO DISCLOSED. THE PREFERRED EMBODIMENT HAS FOUR MODES OF OPERATION-ACTUAL MONITORING, TRANSDUCER DISPLACEMENT MEASURING, CALIBRATION AND TESTING.
