Abstract
PURPOSE: To improve the precision of the measurement of slump value by performing the multiplication of instantaneous value of both voltage and current for driving the motor that drives the concrete mixer and making the effective power proportional to the slump value a detection signal.
CONSTITUTION: Voltage and current of the motor are taken and converted into voltage signals of a proper level 3, 4, converted into instantaneous effctive power 5, and averaged to detect themselves as a basic signal. Next a signal in loading is differentially amplified 7 on making a signal in loading stored in the memory 8 a reference signal, the output is amplified by a parameter corresponding to the mixed amount of concrete 9, and done by a parameter corresponding to the sorts of mixed materials 10. This output is modulated and matched 13 to obtain a signal completely proportional to the slump value, and is displayed 14. In this way, the influcence by both the variation of line voltage and distortion of the wave form can be prevented to measure a slupm value with high precision.
