Description
Block circuit diagram
Supply voltage
Usup = 8 … 12 V
The force sensor comprises a bearing bolt. Shear stress is
encountered at the bearing point. This is recorded as elongation and evaluated.
Signal voltage
Usig = 0.25 … 0.75 Usup
The measuring principle is based on the measurement of
mechanical elongation using strain gauges which are wired to
form a bridge circuit within the force sensor. When not under
load, the bridge is in equilibrium. When a force is applied, the
output signal of the DMS bridge changes, either to positive or
to negative, depending on the direction of the force applied.
This magnitude of the bridge voltage is proportional to the
force applied. It is amplified and rectified in an integrated
­evaluation circuit.
The sensor delivers a ratiometric output voltage (25% to 75%
of the supply voltage). It is available with various measuring
ranges and cable versions. This sensor is a typical component
of an electronic and hydraulic hitch control (EHR).
