50Kg Load Cell

A load cell converts mechanical force into an electrical signal using strain gauges bonded to a metal body. When weight presses down on the 50Kg Load Cell, the alloy steel body deforms slightly — too small to see, but enough for the strain gauges to change resistance. That resistance change produces a millivolt-level output proportional to the applied load. At full 50 Kg capacity, the output sensitivity of 1.0 ± 0.1 mV/V means the signal is predictable and linear across the entire measurement range.

The input resistance of 1000 Ω on this load sensor matches the bridge impedance expected by the HX711 24-bit ADC amplifier — the standard module used with Arduino and ESP32 for digital weight reading. No custom signal conditioning circuit is needed. The alloy steel body handles repeated loading and unloading cycles without creep or zero-point drift that cheaper aluminium body cells develop over time. Four wires exit the cell — red, black, white, and green — corresponding to excitation positive, excitation negative, signal positive, and signal negative on the Wheatstone bridge inside.

The weight load sensor rated at 50 Kg suits platform scale builds, industrial bin weighing, and conveyor load monitoring. One practical note — this cell measures compression force applied along its designed axis. Side-loading or off-axis force introduces error. Mounting should align the load directly above the cell’s central sensing point for accurate readings. Available from StemVolt, this sensor for engineers and makers building precision weighing systems and industrial measurement projects.
