ABSTRACT:
Electronic circuitry senses motion of a load bearing movable element which has a speed relationship as a function of load by establishing a sequence of timing pulses varying in inter-pulse duration time as a function of the movement speed and processes those pulses to produce electronic indicia signals used for control or display purposes. Sampled timing pulses are taken from the sequence to generate a control pulse of predetermined time duration. The control pulse duration is compared with the speed or loading signal comprising a pulse of time duration between sequential timing pulses thereby to produce an indicia analog signal variable over a range of load conditions. The indicia signals is used for display or control functions responsive to the load borne by the movable element within a predetermined analog range.
