ABSTRACT:
A high temperature and high pressure consistometer comprises a cylindrical pressure vessel having an integral bottom and a cover for said pressure vessel. A nonmagnetic canister extends downwardly from said bottom and is sealed therein. A driven magnet assembly is journaled in said canister. A drive shaft is connected to said driven magnet assembly extending into said vessel. A nonmagnetic canister extends upwardly from the cover and is sealed therein. A driving magnet assembly is journaled in said canister. A shaft connected to said driving magnet assembly extends downwardly into said vessel. A driven magnet assembly is mounted for rotation on the exterior of the downwardly extending canister and a driven magnet assembly is mounted for rotation on the exterior of the upwardly extending canister. A sample cup is connected to the upwardly extending drive shaft and a paddle is connected to the downwardly extending shaft. External the vessel is positioned an instrument for measuring the torque magnetically transferred from the shaft carrying the paddle to the driven magnet assembly. External the vessel is a motor for causing the driving magnet assembly to rotate at a constant speed to thereby drive the cup within the vessel at a constant speed.
