The 50kg Half-bridge Experiments Body Scale Load Cell Sensor is a precision strain gauge based sensor designed for measuring force and weight in a half-bridge configuration. It features a strain E-shaped beam with a sensing element affixed to the intermediate section, designed to measure shear forces when pressure is applied to the outer arms of the beam.
This sensor works on the principle of converting mechanical deformation (strain) into a change in electrical resistance. When a force is applied to the outer edges of the beam, it creates shear force that bends the beam, causing strain. The strain gauges in the bridge circuit output a differential voltage proportional to the applied force, which can be amplified and read by a microcontroller via an analog-to-digital converter.
50kg capacity for body scale and weight sensing applications
Half-bridge strain gauge configuration for precision measurement
E-shaped beam design with strain element in the middle
Outputs differential voltage proportional to applied force
Requires signal conditioning for direct microcontroller interfacing
Ideal for load cells, weighing scales, and force measurement experiments
