YZC131 Precision Digital Kitchen Scale – 1Kg Portable Electronic Weighing Scale for Food, Jewelry & Small Items

Description

The YZC131 is a 1Kg capacity strain-gauge load cell designed for precision weighing applications including digital kitchen scales, jewelry scales, portable luggage scales, and small laboratory balances . It is a full-bridge parallel-beam sensor machined from aluminum alloy, with four color-coded lead wires for connection to an HX711 or similar 24-bit ADC amplifier .

When a load is applied to the floating end of the beam, the internal strain gauges deform proportionally, producing a differential voltage signal of approximately 1.0 mV/V at rated capacity . The sensor is compact (approximately 80 × 12.8 × 12.8mm) and lightweight (around 26–50g depending on the source), making it suitable for space-constrained scale designs .

Critical limitations: This is a bare sensor, not a complete scale. It requires external signal conditioning (HX711), mechanical mounting, and calibration. The sensor must be mounted with one end fixed and the load applied to the other end in the direction indicated by the label—never press directly on the white silicone-covered area, as this can damage the strain gauges . Changing the sensor cable length may affect calibration accuracy .
