Abstract
PURPOSE: To display the acceleration of a generating turbine, etc., without artificial calculation by displaying a speed signal fixed in a memory and another speed signal, after fixed time elapses, stored in another memory by differential amplification, etc.
CONSTITUTION: With switch 4b closed, switch 4a closes interlocking to fix a generating turbine rotation-speed signal at the point in time in memory 5 and counters 12 and 13 are both reset to provided digital display of the rotational frequency on display unit 14 through converter 1, detection circuit 3 and counter 13. On the other hand, counter 12 in reset mode counts clocks and when its count value reaches a fixed value after fixed time elapses, relay 6 is excited to close switch 6a. Consequently, a speed signal after the fixed time is stored in memory 7 and memory contents of memories 5 and 7 are inputted to A-D converter 9 through differential amplifier 8, so that the acceleration of the generating turbine, etc., will be displayed by display unit 10 without artificial calculation based upon a speed.
