GEAR TO MEASURE MASS GRAIN FLOW IN ELEVATOR

摘要

A measuring device with a measuring capacitor (C1) through which a mass flow (KS) is conducted as a layered dielectric. The capacitance measuring signal of the measuring capacitor (C1) is supplied via a signal evaluating circuit (M1) and an analog/digital converter (ADU) to an evaluating processor (MP) where it is calculated, in connection with a speed signal (Sv) to form a mass flow value which is supplied to a display (A). A reference capacity measure is obtained on a filled second measuring capacitor (C2). The device is suitable for harvesting machines.
