Pneumatic Consolidation Load Frames have Karol-Warner’s exclusive CONBEL™ design with pneumatic loading that meets the most rigorous demands of soil testing labs. All instantaneously apply and maintain loads for precision consolidation testing and feature low-load functionality for precision application of small confining loads. Loads are applied pneumatically and maintained by a precision pressure regulator. A small cabinet footprint saves valuable bench space. These self-contained devices display applied loads through digital displays and use precision pressure regulators and pressure transducers with linearity of ±0.1%.
The 1in (25.4mm) thick aluminum platforms have adjustable centering pads and are designed to hold any consolidation ring up to 7.25in (184mm) diameter. Platform clearance is 8.25x7.75in (210x197mm), WxH. Stainless steel vertical rods support the cross-head and dial gauge. Sturdy, enamel-coated steel cabinets protect the unit. One HMA-81 Loading Ball is included with each load frame. Fixed or floating-ring consolidometers and a dial indicator are required and purchased separately. An air compressor is required for operation and must be supplied by the user. HMA-608 Consolidation Data Acquisition Software is purchased separately and can be used when the consolidation load frame is equipped with either an HM-739 Linear Variable Displacement Transducer (LVDT) or MA-363 Digital Dial Indicator. This unique software records specimens and real-time test data to calculate results and prepare reports following ASTM and AASHTO requirements. All models operate at 120-220V/50-60Hz.
