ABSTRACT:
The present invention is a consistency transmitter for the measurement of consistency, viscosity, and other properties of matter. The transmitter consists of a measuring element, attached to a bearing-mounted shaft and rotated in the matter to be measured by a direct drive motor that is positioned coaxially with the measuring element and its shaft. The stator of the direct drive motor is integrated into the consistency transmitter body, its rotor into the shaft. The stator is coaxially attached to a first flange that transmits the torsional force of the motor with flexible elements to a second flange positioned on the shaft. The first and second flanges are attached to differential elements with which the phase angle between the flanges is measured using measuring elements located near the flanges. The shaft of the measuring element is bearing-mounted inside a tubular torsion shaft. The consistency transmitter can be inserted into an operating process by means of special installation equipment consisting of a shut-off valve combined with an insertion pipe. The insertion pipe includes regulating elements in such a way that they match with the matching elements on the transmitter body. With the help of regulating elements and matching elements, the transmitter can be inserted to the desired depth in the process.
