Technical details and manufacturing context for Load Sensor

Definition
A critical component within Load Moment Indicator (LMI) systems that measures the actual load being lifted or supported by equipment such as cranes, hoists, and lifting devices. It provides real-time data to the LMI's processing unit to calculate load moment and prevent overload conditions.
Working Principle
Typically operates using strain gauge technology where applied force causes deformation in a sensing element, changing its electrical resistance proportionally to the load. This resistance change is converted into a measurable voltage or current signal.
Common Materials
Stainless steel, Aluminum alloy, Strain gauge foil
Technical Parameters
  • Maximum rated capacity (kg or kN) Per Request
Components / BOM
  • Strain Gauge
    Converts mechanical strain into electrical resistance change
    Material: Constantan or Nichrome foil
  • Elastic Element
    Deforms under applied load to transfer force to strain gauges
    Material: Stainless steel or aluminum
  • Protective Housing
    Shields internal components from environmental damage
    Material: Stainless steel or IP-rated plastic
  • Cable/Connector
    Transmits electrical signals to LMI processing unit
    Material: Shielded copper cable with weatherproof connector
Engineering Reasoning
0-100 kN with ±0.5% full-scale accuracy
150% of rated capacity (150 kN) causes permanent strain gauge deformation
Design Rationale: Exceeding the elastic limit of the strain gauge material (typically constantan alloy with 0.2% proof stress of 310 MPa) leads to plastic deformation and signal drift
Risk Mitigation (FMEA)
Trigger Moisture ingress exceeding 85% relative humidity
Mode: Bridge circuit imbalance causing ±15% signal deviation
Strategy: Hermetic sealing with IP68-rated epoxy encapsulation and desiccant cavity
Trigger Thermal cycling between -40°C and +125°C at 10°C/min gradient
Mode: Fatigue failure of solder joints (Manson-Coffin law: Δε_pl = 0.6(N_f)^{-0.6})
Strategy: Gold-plated contacts with compliant leadframe design and SnAgCu solder (melting point 217°C)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Signal Drift/Calibration Loss
Cause: Thermal cycling, mechanical stress, or aging of internal components (e.g., strain gauges, amplifiers) leading to inaccurate load readings over time.
Electrical Overload/Short Circuit
Cause: Exposure to moisture, corrosive environments, or voltage spikes damaging circuitry, insulation, or sensor elements.
Maintenance Indicators
  • Inconsistent or erratic load readings compared to expected values
  • Visible physical damage (cracks, corrosion) or audible electrical noise/buzzing from the sensor
Engineering Tips
  • Implement regular calibration checks and environmental protection (e.g., sealing, temperature control) to maintain accuracy.
  • Use surge protection devices and ensure proper electrical grounding to prevent overload damage.

Compliance & Manufacturing Standards

Reference Standards
ISO 376:2011 (Calibration of force-proving instruments used for the verification of uniaxial testing machines) ASTM E74-18 (Standard Practice of Calibration of Force-Measuring Instruments for Verifying the Force Indication of Testing Machines) CE marking per EU Directive 2014/30/EU (Electromagnetic Compatibility) and 2014/35/EU (Low Voltage Directive)
Manufacturing Precision

Frequently Asked Questions

What materials are used in your load sensors for durability?

Our load sensors feature stainless steel and aluminum alloy construction with strain gauge foil elements, providing excellent corrosion resistance and long-term stability in industrial environments.

How does a load sensor convert force to electrical signals?

The sensor uses strain gauge foil bonded to an elastic element. When force is applied, the element deforms slightly, changing the electrical resistance of the strain gauge, which is then converted to a measurable voltage signal.

What components are included in your load sensor BOM?

Our bill of materials includes the elastic element, strain gauge, protective housing, and cable/connector assembly, ensuring complete functionality and protection for industrial applications.

Can I contact factories directly on CNFX?

CNFX is an open directory, not a transaction platform. Each factory profile provides direct contact information and production details to help you initiate direct inquiries with Chinese suppliers.
