Micro Load Cell Sensor
Micro load cells use a bridge circuit to detect this resistance change. When a load is applied, the elastic material deforms, causing a resistance imbalance in the bridge. The measurement circuit detects this imbalance and converts it into a digital or analog signal via a converter for display or processing. These load cells are commonly found in a variety of applications, including kitchen scales, medical equipment, and industrial production.
Carefully selected materials: Alloy steel.
Precision CNC machines perform turning, milling, grinding, and drilling processes to ensure each sensor maintains consistent quality.
Waterproof, shockproof, and aging-resistant.
The module surface is anodized for corrosion resistance, and the strain gauge silicone seal achieves an IP65 waterproof rating, effectively preventing risks such as leakage and short circuits.
High-precision Strain Gauges
Excellent heat resistance, minimal creep, and minimal thermal hysteresis.
Excellent long-term stability, high measurement accuracy, and operation in extreme environments, including high and low temperatures and high pressures.

Installation
In an electronic body scale, four strain gauge sensors are connected in series. Each sensor uses a double-stranded plate, which is equivalent to a half-bridge circuit consisting of two strain gauges, resulting in three wires. The red wire is the common output line of the two strain gauges. In a body scale system composed of four sensors, the black wires of the four sensors are connected in series, and the self-wires are connected in series. In this way, the four half-bridges form a full-bridge circuit. The common red wire of each sensor serves as the power supply and output line of the entire full-bridge circuit.
Application of Micro Load Cell Sensor
Micro Load Cell Sensor can be applied in hand scales, kitchen scales, postal scales, fishing scales, baby body scales and other micro electronic weighing systems.
