    Cement Expansion/Shrinkage Tester

    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.

    Features and Benefits
    • Easy to install and use.
    • Continuously measures the expansion or shrinkage of API Cement slurries
    • Single vessel curing to preserve sample conditions and testing integrity. Sample is cured in the vessel, improving sample and test integrity.
    • Programmable temperature and pressure control.
    • Cement is isolated from the pressurizing media using a flexible diaphragm
    • Uses TG-5270 Data Acquisition and Control System for data retrieval, analysis, and storage.
