This straight bar load cell (strain gauge) converts applied force or weight into a proportional electrical signal, with a maximum capacity of 5kg. It uses four strain gauges arranged in a Wheatstone bridge configuration for accurate, stable readings — ideal for building digital scales, weight monitoring systems, and force-sensing applications.

The aluminium-alloy bar construction keeps it lightweight and corrosion resistant. Pair it with an HX711 amplifier breakout board to easily interface with an Arduino or similar microcontroller.
