Abstract
An apparatus for producing an indication of the horsepower produced by a motor, engine or the like in which a load beam mounted on the motor produces a signal which is applied to a torque circuit which includes an A/D converter operating as a dual slope integrating A/D converter to produce a window pulse having a width which varies as a function of detected torque. A tachometer circuit produces a pulse train having a frequency indicating the speed of the motor in revolutions per unit time. The pulses from the tachometer are counted in a horsepower circuit during the window pulse from the torque circuit. Reset and store signals are applied to the counter by a flip-flop responsive to a variable frequency clock and the window pulse. The variable frequency clock drives the A/D converter and can be varied to set the constant K. Seven segment LED displays show the torque, speed and horsepower.
