Description

The YZC-131A load cell operates on the strain gauge principle, where applied force deforms an internal aluminum alloy structure, changing the electrical resistance of bonded strain gauges. This change produces a low-level analog output proportional to the load, which requires amplification via a dedicated module like the HX711 for digital conversion.

Engineered for stability, it features low creep and hysteresis specifications, making it suitable for applications requiring consistent measurement over time. Its compact 75 x 13 x 13 mm form factor and standard M4 mounting holes allow for straightforward integration into scales, force feedback systems, and structural monitoring setups.

Key Features

  • Aluminum alloy construction provides a high strength-to-weight ratio and excellent fatigue resistance.
  • Precision strain gauge technology ensures linear output across the full measurement range.
  • Integrated 18cm cable simplifies wiring to external amplifier circuits.
  • Low zero balance (±0.1 mV/V) minimizes offset error and simplifies calibration.
  • Wide operating temperature range (-21°C to 40°C) supports use in varied environments.
  • High insulation resistance (2000 MΩ) protects signal integrity from electrical noise.
  • Optimized performance-to-cost ratio for educational, prototyping, and light industrial applications.

Applications

  • Bench-top digital scales and precision weighing platforms.
  • Force feedback and tension monitoring in robotic grippers and actuators.
  • Structural load testing and material stress analysis in prototyping.
  • Process control and filling systems requiring weight verification.
  • Educational projects demonstrating strain gauge and transducer principles.

Frequently Asked Questions

What amplifier module is required to use this load cell with an Arduino?

This load cell produces a very small differential analog signal (typically 1.0mV/V). You must use a precision instrumentation amplifier like the HX711 24-bit ADC module. The HX711 amplifies the low-level signal, converts it to digital, and provides a simple serial interface for Arduino, Raspberry Pi, or other microcontrollers.

What is the correct wiring and excitation voltage for this sensor?

The load cell has four wires: red (E+), black (E-), white (S-), and green (S+). Connect E+ and E- to the positive and negative excitation pins on your amplifier (typically 5V). Connect S+ and S- to the corresponding signal input pins. The recommended excitation voltage is between 5V and 10V DC.

How do I mount and calibrate the YZC-131A load cell?

Mount the cell securely using the M4 holes, fixing one end and leaving the other free to deflect. Apply known calibration weights (e.g., 0g, 2.5kg) and record the output from your HX711 module. Use these points in your microcontroller code to create a linear calibration curve for accurate weight readings.
