These Pneumatic Consolidation Load Frames for stress-controlled consolidation testing utilize the popular CONBEL™ pneumatic loading system. This series is a refinement of the original design and incorporates greater sensitivity and ease of operation. Loads are applied instantaneously and maintain any determined set-point, regardless of sample compression during the loading interval. Models are available in 16, 32 and 64tsf load ranges based on a 2.5in (63.5mm) diameter sample. Load frames come with a loading ball and 15ft (4.6m) of air supply tubing.
The CONBEL™ system features a low-bleed pressure regulator to set and maintain specimen loads. Known for precision, this regulator is sensitive to 0.125in (3.2mm) variations in water column. It requires a source of compressed air for operation. The unit is self-contained with a built-in digital readout and pressure transducer with 0.1% linearity.
The load platform is 1in (25.4mm) thick aluminum plate, and features adjustable centering pads to aid in aligning the consolidometer. It will accept any consolidometer, regardless of manufacturer, up to a maximum diameter of 7.25in (184mm). Vertical rods are made from stainless steel. Fabricated for harsh laboratory environments, the cabinets are steel and painted with a durable enamel. Consolidometers and Dial or Digital Displacement Indicators are sold separately.Pneumatic Consolidation Load Frames use the reliable and accurate CONBEL™ system for precise application and maintenance of force regardless of sample deformation. The user’s compressed air source is controlled through a precision regulator to generate instant loads with no impact. These devices are comparatively insensitive to forces from shock or inertia, and accept Consolidometers from any manufacturer up to 7.25in (184mm). Capacities, based on use of a 2.5in (63.5mm) Consolidometer, are 16, 32, and 64tsf (1,532, 3,064 and 6,129kPa).
