Abstract: Control apparatus for producing a control signal indicating that a physical variable has reached a userselected level. A transducer generates for the control apparatus electrical pulses having a repetition period which is a function of the physical variable. The control apparatus repeatedly counts clock pulses in response to the transducer pulses to provide a first digital signal representative of the repetition period of the transducer pulses. The apparatus also repeatedly generates a second digital signal corresponding to the user-selected level of the physical variable by adding to a preset binary code a binary amount related to a userselected voltage. The first and second digital signals are compared to produce the control signal for a switching circuit which responds thereto. The comparison is overriden if an analysis of most significant bits of the first digital signal shows that the physical variable varies beyond a predetermined level.
