Low creep and hysteresis silicon load cell based on a force-to- liquid pressure transformation
نویسندگان
چکیده
Important problems in load cells are creep and hysteresis. Expensive high grade steels are used in order to reduce these effects. In this paper a silicon load cell design is presented which is based on a force-to-liquid-pressure transformation. The design is insensitive to hysteresis and creep, can be made at very low costs and is able to measure loads up to 1000 kg with an accuracy of 0.03 %. Analytical, numerical and experimental results on a macroscopic steel load cell are in very close agreement with each other.

متن کاملHigh force 10 kN piezoresistive silicon force sensor with output independent of force distribution
A silicon force sensor is realized in which the force is measured by compressing a meander shaped polysilicon strain gage. A second gage which is not loaded, is used for temperature compensation, for compensation of bending and stretching stresses in the chip and for common changes in zero load resistor values. It is shown that the output of the bridge is a linear function of the force and is i...
متن کاملLow-cost piezoresistive silicon load cell independent of force distribution
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...

متن کاملSound Wave Propagation in Viscous Liquid-Filled Non-Rigid Carbon Nanotube with Finite Length
In this paper, numerical results obtained and explained from an exact formula in relation to sound pressure load due to the presence of liquid inside the finite-length non-rigid carbon nanotubes (CNTs), which is coupled with the dynamic equations of motion for the CNT. To demonstrate the accuracy of this work, the obtained formula has been compared to what has been used by other research...
