Soil pressure mini-sensor made of monocrystalline silicon and the measurement of its sensitivity coefficient

Abstract

A calibration test was done in order to measure its sensitivity coefficient by an improved soil test derice. The experimental result shows that the soil pressure min-sensor made of the monocrystalline silicon (SPM-MS) is proved to be good linear, high precision and less discrete that can fetch precise data in low pressure range even near by O point, which guarantees the reliability of the soil pressure test in geotechnical engineering.

Keywords
