Measuring principle
The principle is simple; a circular load shaped stainless steel cell, is equipped with strain gauge sensors fixed internally to the longitudinal part, guaranteeing sensitivity of 10 ÷ 20Kg/cm2
The load on the cell deforms its longitudinal body, the strain is perceived by the sensor and measured and data provided as a variation of resistance.
Appropriate portable and automatic units are available for taking measurements.. Special regularization and load distribution plates optimize the installation of the instrument. Instruments with simple Bourdon pressure gauge without automatic sensors are available.
