Component Specifications

Definition
A spring element, also known as an elastic body, is a precision mechanical component designed to deform elastically under applied force. In force sensors and load cells, it serves as the primary sensing element that converts mechanical force into measurable strain or displacement. This deformation is typically measured using strain gauges or other displacement sensors to calculate the applied force with high accuracy.
Working Principle
Operates on Hooke's Law (F = kx), where applied force causes proportional elastic deformation. This deformation is measured via attached strain gauges in a Wheatstone bridge configuration, converting mechanical strain into electrical resistance changes that correlate to force magnitude.
Materials
High-strength alloy steel (17-4PH, 4340), aluminum alloys (7075-T6), beryllium copper, or titanium alloys; selected for high yield strength, low hysteresis, and stable elastic modulus across temperature ranges.
Technical Parameters
  • Creep <0.02% FS/30min
  • Hysteresis <0.02% FS
  • Nonlinearity <0.03% FS
  • Safe Overload 150% FS
  • Capacity Range 5N to 5000kN
  • Natural Frequency 500-5000 Hz
  • Ultimate Overload 300% FS
Standards
ISO 376, DIN 51301, ASTM E74

Frequently Asked Questions

What is the difference between a spring element and a load cell?

The spring element is the core elastic component within a load cell that deforms under force, while the load cell is the complete measurement device that includes the spring element, strain gauges, electronics, and housing.

How does temperature affect spring element performance?

Temperature changes affect material elastic modulus and thermal expansion. High-quality spring elements use materials with low temperature coefficients and may include temperature compensation in the strain gauge circuit.

What maintenance do spring elements require?

Spring elements require protection from overload, corrosion prevention, periodic calibration verification, and inspection for physical damage or fatigue cracks in high-cycle applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
