This device is used to maintain cell pressure constant for a long duration and the system can be used in place of conventional constant pressure system using mercury post where certain minimum heights are required. Problems like de-airation of pump, leakage of mercury etc. are eliminated in this system. This unit is smaller in volume and can be used in mobile laboratory also. This can maintain pressure in the cell upto 20 kg / cm². Pressure is maintained constant in the system by a balancing calibrated weighs on a spindle against a column of oil, operating under constant feed back.
CONSTANT PRESSURE SYSTEM - OIL WATER. 20 Kg / cm2.
Order Code: AIC-CPSOW-20.

The system consists of an oil
pump continuously driven by an electric motor during the test period. The
internal components are housed in a strong compact housing. The piston on
which weights are kept rotates with minimum friction. A transparent oil
water vessel is provided to transmit pressure to the cell.
A hand pump provided to
facilitate priming and to maintain constant pressure during power failure.
