Description

The YZC-133 is a straight-bar, resistive strain gauge load cell designed for precision weighing and force measurement applications. It operates on the principle of a Wheatstone bridge, where applied force alters the resistance of bonded strain gauges, producing a proportional millivolt-level differential output signal. This analog signal requires conditioning via an instrumentation amplifier or a dedicated 24-bit analog-to-digital converter (ADC) like the HX711 for microcontroller integration.

Constructed from aluminum alloy and sealed to IP65 standards, the sensor is protected against dust ingress and water jets, making it suitable for use in industrial scales, process control, and testing equipment. Its low creep (0.03% F.S./30min) and hysteresis specifications ensure stable, repeatable measurements under sustained or cyclic loading conditions. The sensor is mounted via four threaded holes (two M3.3 and two M4) with one end fixed and the other floating to properly transfer the applied load to the sensing element.

Key Features

  • High-Precision Strain Gauge Design: Four active gauges in a full-bridge configuration for superior sensitivity and temperature compensation.
  • Low-Creep Aluminum Alloy Body: Minimizes signal drift under constant load for reliable long-term measurement.
  • IP65 Environmental Sealing: Provides protection against dust and water jets for use in demanding industrial or washdown environments.
  • Wide Input Voltage Range: Compatible with 5-10V DC excitation, offering flexibility in system power design.
  • Comprehensive Performance Specs: Features low nonlinearity (±0.03% F.S.), excellent repeatability (0.05% F.S.), and a high 2000 MΩ insulation resistance.
  • Integrated 18cm Cable: Pre-wired with color-coded leads for straightforward connection to signal conditioners or ADC modules.

Applications

  • Bench-top Electronic Scales: Core sensing element for precision scales up to 20kg capacity in laboratory, kitchen, or postal applications.
  • Industrial Process Control: Force feedback and weight monitoring in filling machines, batch reactors, and conveyor belt checkweighers.
  • Embedded System Prototyping: Integration with Arduino, ESP32, or Raspberry Pi via HX711 ADC modules for DIY smart scales, force gauges, and load monitoring systems.
  • Mechanical Testing & Safety Equipment: Measurement of static and dynamic loads in material testing jigs, safety overload switches, and structural health monitoring.

Frequently Asked Questions

What is the recommended excitation voltage for the YZC-133 load cell?

The YZC-133 load cell is designed for a 5 to 10V DC excitation voltage. Applying voltage within this range to the Red (+) and Black (-) input wires ensures the rated 1.0mV/V output sensitivity and proper bridge operation. Exceeding 10V may cause overheating and damage the internal strain gauges.

How do I connect this load cell to an Arduino or microcontroller?

You cannot connect the load cell directly to a microcontroller's analog pin. The millivolt-level differential signal must first be amplified and digitized. Connect the load cell's four wires (Red, Black, Green, White) to a 24-bit ADC module like the HX711, following its color-coding guide. Then, connect the HX711's DATA and CLK pins to digital I/O pins on your Arduino, ESP32, or other MCU.

What does the IP65 rating mean for this sensor?

The IP65 rating indicates the load cell is dust-tight (IP6X) and protected against low-pressure water jets from any direction (IPX5). This makes it suitable for use in environments where it may be exposed to dust, splashing water, or light washdowns, such as in food processing, agricultural, or industrial settings. It is not submersible.

How should I mount the YZC-133 load cell for accurate measurements?

Mount the load cell using the four provided threaded holes (two M3.3 and two M4). Fix one end securely to a stable base, leaving the opposite end in a floating state to allow force application. Force must be applied axially along the center of the bar, in the direction indicated on the label, to avoid side loads that cause measurement errors. Never apply force directly to the white plastic cable cover.
