## Description

A 20 kg strain gauge load cell with four wires, featuring a metallic foil gauge bonded with epoxy to a solid aluminium bar. The aluminium constrains deflection and protects the gauge from damage. Mount one end to a fixed surface using the mounting holes, then apply force to the other end in the direction indicated on the label. The output resistance changes proportionally with applied force and is measured using a precision ADC or Wheatstone bridge circuit (such as the HX711 load cell amplifier). Specifications Capacity – 20 kg Wires – 4-wire connection Body Material – Aluminium Output – Analogue (requires external ADC or amplifier) Ideal For DIY weighing scales and force measurement Pressure and tension monitoring Arduino and microcontroller-based weight systems Industrial and scientific load sensing Note: No ADC or converter is included. The load cell must be calibrated with known weights once installed. For best precision, choose a load cell with at least 2× the maximum force you intend to measure.

**Product Type:** physical
