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

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.

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.
