Dead Weight Type Oil and Water Constant Pressure System

Model No.: TVELE-0002
Standards: 0002

Specification: 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 pots where certain minimum heights are required. Problems like de-airation of pump, leakage of mercury etc. is 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 20kg/cm sq. Pressure is maintained constant in the system by a balancing calibrated weights on a spindle against a column of oil, operating under constant feed back.

Construction: 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 facilitates priming and to maintain constant pressure during power failure

Specification:

• Range 0-20 bar(0-20kg/cm2)
• Steps of Pressure 0.5bar (0.5kg/cm2)
• Accuracy + 0.5%
• Electric supply 230V, Single Phase, 50Hz, AC supply.
• Supplied complete with pressure gauge, flow valves, connecting pressure hose and set of weights to give maximum pressure of 20 bar (20 kg/cm2
