Abstract

A silicon load cell (force sensor) is presented which is based on a new operating principle. The force is measured by compressing a meander like strain gage. A second strain gage which is not loaded, is used for temperature compensation and for compensation of bending and stretching stresses in the chip. Also, same changes in zero load resistor values are eliminated. It is shown that the output of the bridge is a linear function of the total force and independent of the force distribution on the silicon chip. Measurements up to 1000 kg show a linear respons and a short term repeatability which is within 0.1 %. Creep after 30 minutes is within 1.2 %.
