Technical details and manufacturing context for Force Sensor/Load Cell

Definition
A critical component within Force & Position Control Systems that precisely measures force, tension, compression, or weight. It provides real-time feedback to the system controller, enabling accurate force regulation, overload protection, and process monitoring in automated industrial applications.
Working Principle
Typically operates on the principle of strain gauges bonded to a metal element (spring element). When force is applied, the element deforms slightly, causing a change in electrical resistance of the strain gauges arranged in a Wheatstone bridge circuit. This change in resistance produces a proportional millivolt-level output signal that is amplified and interpreted by the control system.
Common Materials
Stainless Steel, Aluminum Alloy
Technical Parameters
  • Rated capacity or maximum force the sensor is designed to measure accurately. (N, kN, lbf) Customizable
Components / BOM
  • Spring Element (Elastic Body) Part
    The core structural component that deforms elastically under applied force. Its design (beam, shear beam, S-type, canister) determines the sensor's force application type and capacity.
    Material: Stainless Steel (e.g., 17-4PH, 304) or Aluminum Alloy
  • Strain Gauges Part
    Precision resistors bonded to the spring element. Their resistance changes proportionally to the strain (deformation) of the element, forming the sensing mechanism.
    Material: Constantan or Karma foil on polyimide substrate
  • Sealing / Enclosure Part
    Protects the internal strain gauge assembly and wiring from environmental factors like dust, moisture, and chemical exposure, as defined by the IP rating.
    Material: Stainless Steel, Nickel-plated Steel, or Epoxy Resin
  • Cable or Connector Part
    Provides the electrical interface for excitation voltage input and signal output to the system's amplifier or controller.
    Material: PVC, PUR, or TPE sheathing with copper conductors
