Abstract
An apparatus for carrying out a weight measurement in centrifuges for separating suspensions into their solid and liquid components comprises a machine housing, a drum rotatingly mounted in the machine housing and receiving the suspension, and a filler pipe leading into the drum for feeding the suspension into the drum. The machine housing is mounted for pivotal movement about an axis of rotation, and a force measuring element senses weight-dependent deflections of the machine housing occurring about the axis of rotation and originating from a different degree of filling of the drum with suspension or from a different dewatering of the solid suspension components, and the machine housing deflections are indicated on a measurement value indicator. A pipeline is provided for generating a positive pressure or a negative pressure in the drum. The line of application of the force generated in this pipeline on account of the positive pressure or the negative pressure is guided so as to intersect the axis of rotation of the machine housing, or a sensor is provided for sensing the pressure in the drum and correcting the measurement value indicator in dependence upon the pressure.
