Inside the aluminum body, four strain gauges are strategically bonded to the metal and wired into a Wheatstone Bridge configuration. This setup ensures that temperature changes and electrical noise are minimized, leaving only the pure weight data.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eKey Features \u0026amp; Build:\u003c\/strong\u003e\u003cbr\u003e3kg Capacity: This model offers a higher weight limit than the common 1kg version, making it perfect for postal scales, coffee scales, or small parts counters.\u003cbr\u003e\u003cbr\u003eStrain Gauge Precision: The internal sensors detect microscopic \"stretching\" of the aluminum bar. This deformation is so small it is invisible to the eye, but the sensor can translate it into a readable electrical signal.\u003cbr\u003e\u003cbr\u003eDurable Construction: The aviation-grade aluminum alloy is stiff enough to prevent permanent bending (creep) while remaining flexible enough to provide accurate data across its entire 3kg range.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTechnical Capabilities:\u003c\/strong\u003e\u003cbr\u003eSensitivity (Rated Output): 1.0 ± 0.1 mV\/V.\u003cbr\u003e\u003cbr\u003eExcitation Voltage: Recommended 5V–10V (usually provided by the HX711).\u003cbr\u003e\u003cbr\u003eSignal Output: Because the output is in millivolts, you must use an HX711 Amplifier to convert the signal into digital data for your Arduino or ESP32.\u003cbr\u003e\u003cbr\u003eWiring Standard:\u003cbr\u003e\u003cbr\u003eRed: Excitation + (E+)\u003cbr\u003e\u003cbr\u003eBlack: Excitation - (E-)\u003cbr\u003e\u003cbr\u003eWhite: Signal - (A-)\u003cbr\u003e\u003cbr\u003eGreen: Signal + (A+)\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eInstallation \u0026amp; Mechanical Setup:\u003c\/strong\u003e\u003cbr\u003eThe physical mounting of a load cell is the most common cause of inaccurate readings.\u003cbr\u003e\u003cbr\u003eCantilever Mounting: The bar must be mounted so that it can \"flex.\"\u003cbr\u003e\u003cbr\u003eBolt the fixed end (where the wires exit) to a heavy, stable base.\u003cbr\u003e\u003cbr\u003eBolt the floating end to your weighing platform.\u003cbr\u003e\u003cbr\u003eEnsure there is a physical gap (using spacers or washers) between the bar and the base so it doesn't touch anything as it bends under weight.\u003cbr\u003e\u003cbr\u003eDirection of Force: Look for an arrow on the side of the load cell. This arrow indicates the direction of the load. If you mount it upside down, your weight readings will show up as negative numbers.\u003cbr\u003e\u003cbr\u003eStrain Relief: Ensure the thin wires coming out of the sensor are taped or glued to the fixed base. If these wires pull on the internal gauges, it will cause \"drift\" in your measurements.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e\u003cbr\u003eThe 3kg load cell is the ideal choice for digital platform scales, automated inventory systems, smart parcel bins, and scientific balances.\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46397426598087,"sku":"TE-LOADC-059","price":191.53,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/LoadCell3kg_1.png?v=1776755356","url":"https:\/\/shop.tinkedge.tech\/products\/load-cell-3kg","provider":"TinkEdge","version":"1.0","type":"link"}
