Consistometer

摘要

An improved consistometer which continuously measures the consistency of a stream of material from apparatus manufacturing the material includes a resilient blade rotated in the stream of material and which is rotated about an axis that is parallel to the direction of flow of the stream of material. A reference blade is rotated in synchronism with the resilient panel. A pair of detectors are arranged with the blade in the manner so that each detector detects the passage of a corresponding blade and provides a corresponding electrical signal. A circuit connected to the detectors provides a start pulse and a stop pulse in accordance with the signals from the detectors and not to noise. A clock provides timing pulses. A network connected to the start and stop pulse circuit and to the clock determines the consistency of the material in accordance with the start and stop pulses and the timing pulses.
