{"title":"Strain Gauge Load Cell - 4 Wires - 20Kg","handle":"strain-gauge-load-cell-4-wires-20kg","url":"/products/strain-gauge-load-cell-4-wires-20kg","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.\n\nThe 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).\n\nSpecifications\n\n\nCapacity – 20 kg\n\nWires – 4-wire connection\n\nBody Material – Aluminium\n\nOutput – Analogue (requires external ADC or amplifier)\n\n\nIdeal For\n\nDIY weighing scales and force measurement\nPressure and tension monitoring\nArduino and microcontroller-based weight systems\nIndustrial and scientific load sensing\n\n\n\nNote: 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.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3986,"title":"Default Title","sku":"AF-4543","price":7.71,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
