Consolidation Load Frames (Pneumatic)

These Pneumatic Consolidation Load Frames for stress-controlled consolidation testing utilize Karol-Warner's exclusive 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 16tsf (1,532kPa), 32tsf (3,064kPa), and 64tsf (6,128kPa) 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 the 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 loading 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 durable enamel. Consolidometers and Dial Indicators are sold separately. See our main Consolidation Machine page to compare load frame types. All models operate at 120-220V/50-60Hz.
