Any dissolved air in the water will lead to errors in the measurement of pore pressure, particularly at low pressures, and also give slow or incorrect saturation results.De-Aired Water ApparatusProduct Code: 25-1833/01This compact self-contained unit will de-air water quickly and efficiently down to levels of dissolved oxygen acceptable for geotechnical test methods. Air is removed from the water by a vacuum system, which continuously circulates the water in the tank. The unit is supplied with a clear water container, which will hold a maximum of 15 litres of water. Input and output lines are formed using standard 6 mm tube connectors.SpecificationsSelf-ContainedYesCapacity (ltrs)15DimensionsL x W x H (mm)380 x 356 x 470Power Supply220-240 V AC, 50-60 Hz, 1 phWeight (kg)13Spares/Consumables:Pump (5020X0073)Tank (9004A0073)Gasket (1617B0012) Soil Testingwww.ele.com • email: ele@eleint.co.uk • tel: +44 (0)1525 249 20063Soil Strength (Triaxial)Pressure SystemsAir Compressor Unit 1000 kPaProduct Code: 83-1735/01SpecificationsDimensionsL x W x H (mm)1321 x 457 x 914Free Air Delivery6.0 cfmReceiver Capacity (ltrs)116Max Pressure1380 kPaContinuous Working Pressure1000 kPaPower Supply220-240 V AC, 50 Hz, 1 phWater TrapYesWeight (kg)149We offer a range of products designed to supply and monitor all those parameters necessary for the successful testing of geotechnical materials. Two types of constant pressure systems are available: ±Air/water system operated by a pneumatic compressor. ±A motorised oil/water system.Air/Water Pressure SystemsWhere a laboratory requires a number of constant but independent and variable pressure sources, the use of a pneumatic compressor is recommended. Depending on the capacity and volume of the unit, a series of pressure sources can be provided to various test stations around the laboratory. Compressed air must be delivered to a system designed to transfer the controlled pressure to the fluid (usually water), which applies the various test pressures, e.g. a confining pressure in a triaxial test. The pressure reducing panel is used in conjunction with a bladder-type air/water interface assembly. Each individual pressure take off from the reducing panel will require a bladder interface assembly. Connection of the reducing panels to the compressor/water trap outlet and to other reducing panels requires the use of nylon tubing.Air/Water Bladder-Type Pressure AssemblyProduct Code: 26-1746With transparent plastic chamber for operating continuously at pressures up to 1000 kPa. A length of tubing is provided for connecting the air/water cylinder outlet to a pressure measuring system. ±Used to supply hydraulic pressure from a pneumatic pressure source. ±Prevents air entering the hydraulic pressure system. ±Maximum working pressure 1000 kPa. ±Supplied with connectors and tubing for fitting to pressure measuring systems.SpecificationsWeight (kg)5.6Spares/Consumables:Plastic Hose Clip (8412X0260)‘O’ rings for upper + lower 5 inch cell (8447X1143)Replacement Bladder (38 mm internal dia) (26-1746/10)tel: +44 (0)1525 249 200 • email: ele@eleint.co.uk • www.ele.com64Soil Strength (Triaxial)Soil TestingAir Compressor Unit 700 kPaProduct Code: 83-1730/01SpecificationsDimensionsL x W x H (mm)483 x 457 x 864Free Air Delivery2.0 cfmReceiver Capacity (ltrs)50Max Pressure1000 kPaContinuous Working Pressure700 kPaPower Supply220-240 V AC, 50 Hz, 1 phWater TrapNoWeight (kg)57Pneumatic Pressure Reducing Panel.
