A Transducer to Measure Pore Water Pressures in Soil Tests


A pressure transducer with very small volume compliance has been adapted to measure and record the pore water pressures which develop during loading tests on saturated soil specimens in the laboratory. The technique described uses an unbonded strain gage type of pressure transducer. Details are given of the ancillary electrical circuitry, the method of mounting, and the calibration of the system.
