LPS110A

The force sensor is constructed as a bearing bolt. Shear stress occurs at the bearing position, manifesting as a magnetoelastic effect. In the no-load state, a symmetrical magnetic field is formed between the two poles due to the action of the primary coil. If a tensile or compressive force is introduced, the magnetic properties of the originally isotropic material change. As a result, the magnetic field becomes asymmetric. This leads to a magnetic potential difference between the secondary electrodes, which in turn causes magnetic flux to pass through the secondary circuit, inducing a voltage in the secondary coil. This voltage is proportional to the applied force and is amplified and rectified in an integrated evaluation circuit. The sensor provides a ratio voltage (25% to 75% of the supply voltage). It is available in various measurement ranges and cable versions. This sensor is a typical component of Electro-Hydraulic Control (EHC). This sensor is specifically designed for agricultural technology applications.
