Soil Testing Machines

Air-Water Type
This constant pressure system is operated pneumatic pressure, applied through a compressed air line. Where more than one outlet are to be taken from a single pressure source, it is simple to use an Air-Water Constant Pressure System. Equipment is provided with three air water interface chambers with individual regulators to control the outlet pressures at desired pressure levels. The interface chambers are provided with acrylic plastic chambers and two ball valves for outlet and inlet of water. The chambers are fixed over a console, which houses the three regulators and three pressure gauges. It is also possible to increase the number of chambers on request. Maximum pressure: 700 KPa (7 kg/cm2) Supplied complete with three outlet pressure hoses.

Oil-Water Type
Dead Weight Type Oil-Water Constant Pressure System is an extremely versatile apparatus, which can be used for a wide range of applications. This system provides an effective alternative to the accepted Mercury and Water Constant Pressure System where the use of mercury is objectionable and laboratory headroom is insufficient. The apparatus is designed to provide confining pressure upto 20 bar (20 kg /cm2) to Triaxial Cells.

Features

• Use of Mercury is eliminated
• Maintains Constant Pressure continuously
• Pressure Capacity, 20 bar (20 kg/cm2)
• Ideal for mobile laboratories

Working Principle
Constant Pressure is maintained in the system by balancing a set of calibrated weights on a spindle against a column of oil, operating under constant feedback conditions.
