TAL220 Miniature 10 kg Load Cell — Technical Product Documentation

⚖️ High-Precision Sensing | Compact Form Factor | OEM-Ready | Low-Noise Output


📘 Product Overview

The TAL220 miniature 10 kg load cell is engineered for compact, high-accuracy weight and force sensing within constrained mechanical assemblies. Its stable output, miniature profile, and repeatable behavior make it ideal for food-automation systems, robotic grippers, smart dispensing units, laboratory balances, and embedded weighing platforms.

Designed for OEMs building reliable measurement systems, the TAL220 provides:

  • Precise force/mass measurement
  • Excellent repeatability and low noise
  • Compatibility with standard analog-to-digital converters (e.g., HX711)
  • Reliable mechanical integration through optimized mounting interfaces

Its strain-gauge-based Wheatstone bridge architecture ensures predictable linear response even under continuous or cyclic loads.

⚙️ Engineering Design Details

1. Strain Gauge Architecture — Wheatstone Bridge

  • Utilizes bonded foil strain gauges arranged in a full Wheatstone bridge
  • Converts mechanical deformation into a stable differential millivolt signal
  • Offers high resolution, low thermal drift, and strong noise immunity

Performance Characteristics:

  • Typical output: 1–2 mV/V at full scale
  • Excellent linearity and minimal hysteresis
  • Stable signal response under cyclic loading

2. Mechanical Geometry & Load Path

Beam Profile:

  • Miniature bar-type or S-type beam element, tuned for controlled linear deflection
  • Geometry optimized to reduce hysteresis and maximize sensitivity

Deflection Behavior:

  • Very small elastic displacement under 10 kg load
  • Prevents plastic deformation while maintaining high signal resolution

3. Material Selection

  • Constructed from aircraft-grade aluminum alloy or hardened steel
  • Predictable elastic behavior with tight thermal expansion coefficients
  • Corrosion-resistant finish suitable for food-automation and industrial settings

4. Mounting Interface

Includes tapped holes or through-holes for secure integration:

  • One side bolts to a base plate
  • Opposite side attaches to a loading platform or force-transfer bracket

Correct torque and alignment ensure:

  • Maximum linearity
  • Low off-axis error
  • Optimal long-term stability

5. Electrical Output & Signal Conditioning

  • Produces millivolt-level differential output requiring external amplification
  • Compatible with:
    • Standard load-cell amplifiers
    • HX711 ADC modules
    • Custom embedded measurement circuits

Cable Assembly:

  • Shielded multi-core cable minimizes EMI
  • Color-coded wiring: Excitation+, Excitation–, Signal+, Signal–

6. Environmental Engineering

  • Sealed with protective coatings to resist humidity, moisture, and particulate ingress
  • Suited for food-environment vibrations, robotics, and industrial machinery
