3. determining the temperature of the heating bath and slurry The slurry cup is rotated through the use of a DC electric motor and timing belt and pulley system The rotational speed of the slurry cup is set at the factory at 150 rpm The speed may be changed by the user using the potentiometer inside the cabinet provided a satisfactory tachometer is available The consistency of the cement slurry in a non recording atmospheric consistometer is measured by a torsion spring and pointer mechanism found on the lid of the slurry cup The pointer is coupled with a torsion spring to resist the rotating force of the paddle The rotational force is proportional to the consistency of the cement slurry and is measured through the pointer as the spring deflects under load The consistency is indicated by the pointer and dial on the slurry cup lid The dial is graduated in units of consistency from 0 10 A reading of 7 on the lid corresponds to a Bearden Unit Bc value of 70 Bearden units are defined in API Specification 10 The consistency of the cement slurry in a recording consistometer is measured by a torsion spring and potentiometer mechanism found on the lid of the slurry cup The potentiometer is coupled with a torsion spring to resist the rotating force of the paddle The rotational force is proportional to the consistency of the cement slurry and is measured through the potentiometer as the spring deflects under load The consistency is displayed
