More Information on Consolidometer Selection
Durham Geo offers both the pneumatic loading consolidometer (S-450 Terraload) and the lever type consolidometer (S-449 dead weight Load Frame). The following may help in choosing between a pneumatic or lever type consolidation frame:
- requires less space in the lab than a dead weight device.
- has a lesser chance of being bumped compared to the lever type.
- is easier to operate when it comes to adding loads to the sample. Operators tend to prefer turning a valve rather than carefully adding a weight by hand. The weight on the dead weight device can be added too fast or too slow and affect results. The weight works fine, but takes some operator experience.
- requires a source of compressed air. This is an additional expense. There is also a chance that the power will fail, thus a chance of “loosing the sample”. The lever type requires no external source of air, and is independent of electrical power or air compressor failures.
- is considered to be more accurate than the pneumatic frame at very low loads.
- slightly less costly to set up, but the pneumatic frame costs less when multiple units are purchased. This is because one S-45040 Digital Readout and pressure transducer can be used with multiple S-450 units.
