Product Specifications

Technical details and manufacturing context for Load Cells

Definition
Load cells are precision sensors installed within weighing hoppers to measure the weight of materials by detecting the force exerted on them. They provide accurate weight data for process control, batching, and inventory management in industrial weighing systems.
Working Principle
Load cells operate on the principle of strain gauge technology. When force is applied to the load cell, it causes deformation (strain) in the sensing element. This deformation changes the electrical resistance of strain gauges bonded to the element, producing a proportional electrical output signal that can be calibrated to weight measurements.
Common Materials
Stainless steel, Aluminum alloy
Technical Parameters
  • Maximum capacity rating (kg) Standard Spec
Components / BOM
  • Strain Gauge
    Converts mechanical strain into electrical resistance change
    Material: Constantan foil
  • Elastic Element
    Deforms under applied load to create measurable strain
    Material: Stainless steel
  • Sealing
    Protects internal components from environmental factors
    Material: EPDM rubber
Engineering Reasoning
0-1000 kN with 0.03% FS accuracy at 20°C
150% of rated capacity (1500 kN) causes permanent deformation of strain gauge elements
Design Rationale: Plastic deformation of strain gauge foil beyond 0.2% strain, exceeding Hooke's Law elastic limit (σ_y = 250 MPa for Constantan alloy)
Risk Mitigation (FMEA)
Trigger Moisture ingress exceeding 85% RH for >1000 hours
Mode: Corrosion-induced bridge imbalance causing 5% zero-point drift
Strategy: Hermetic sealing with IP68 rating and desiccant-filled cavity
Trigger Thermal cycling between -40°C and +85°C at 10°C/min gradient
Mode: Differential expansion cracking solder joints (CTE mismatch: PCB 17 ppm/°C vs Constantan 15 ppm/°C)
Strategy: Strain-relief wire bonding with silicone encapsulation

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Zero Drift
Cause: Thermal expansion/contraction of strain gauge materials due to temperature fluctuations, causing permanent calibration shift.
Signal Instability/Noise
Cause: Moisture ingress or corrosion at electrical connections, compromising Wheatstone bridge integrity and introducing electrical interference.
Maintenance Indicators
  • Erratic or fluctuating readings under constant load (indicating electrical issues or mechanical damage)
  • Visible corrosion, moisture, or physical deformation on the load cell body or mounting hardware
Engineering Tips
  • Implement environmental protection: Use sealed, IP-rated load cells with proper cable glands and moisture barriers; maintain stable ambient temperatures where possible.
  • Ensure proper mounting and alignment: Use manufacturer-specified hardware, avoid side loads or torsion, and verify free movement to prevent mechanical stress concentrations.

Frequently Asked Questions

What materials are used in these load cells and why?

Our load cells are constructed from stainless steel for corrosion resistance in harsh environments and aluminum alloy for lightweight applications requiring high strength-to-weight ratios.

How do load cells convert force into electrical signals?

Load cells use strain gauges bonded to an elastic element. When force is applied, the element deforms slightly, changing the electrical resistance of the strain gauges, which is measured as a proportional electrical signal.

What maintenance do industrial load cells require?

Proper sealing protects internal components. Regular calibration checks, visual inspections for damage, and ensuring clean mounting surfaces are essential for maintaining accuracy in machinery applications.

Can I contact factories directly on CNFX?
