Model TG-4268
TG-4268 Cement Expansion/Shrinkage Tester is used to measure the expansion or shrinkage of a cement sample under high temperature and high-pressure conditions.
The system measures the change in volume of the sample using a diaphragm and displacement piston combined with a precision LVDT (Linear Variable Displacement Transducer). The resulting translation of the piston is scaled in units of milliliters (mL) or % expansion. The data is presented graphically using TG-5270 Data Acquisition and Control System.
TG-4268 Cement Expansion/Shrinkage Tester is equipped with the programmable temperature controller and a programmable pressure controller. Using the controllers, multiple segment ramp and dwell temperature and pressure schedules may be defined for the sample.
