Abstract
A programmable cycle meter assembly (17,117) for monitoring a cycling member by receiving an input signal from a transducer (13,113) proportional to the cycles of the monitored member and for indicating various cycle rates by a speedometer or tachometer (36) in linear proportion to a linear array of corresponding frequencies. The assembly includes a circuit (17, 117) which is characterized by a switchable filter means (12,112) which filters out unwanted frequencies above a predetermined frequency of the input signal from the transducer (13,113). a switchable divider (20,120) is used for adjustably dividing the input signal for changing the proportion of the frequency by variable a predetermined ratio to produce a repetitive rate (24,124). A fixed frequency to voltage converter (28,128) converts the repetitive rate adjusted frequency signal (24,124) into a proportional voltage for indicating cycle rate on a meter (36) for various configurations of the cycling member.
