    Mini Annular 30kn Load Cell 5-50kn Donut Force Sensor ...
    An annular force transducer, or annular load cell/load washer, is a specialized sensor with a central hole designed for measuring compressive forces in tight spaces, such as bolt tensioning, clamping force tracking, and through-hole applications. These sensors offer high-precision, low-profile measurement (typically ranging from
    10
    kN
     to
    200
    kN
    ) for industrial fasteners and assembly. 
    Key Features & Applications 
    • Design: Often called "doughnut" load cells, they are commonly used to measure screw or bolt tightening forces.
    • Accuracy: High-precision models (like the KR111) can achieve 0.1% accuracy for tension and compression up to
      ±50
      kN
      .
    • Customization: Available in miniature sizes (e.g., M6, 34 mm diameter) for restricted mechanical environments, with outputs like 4-20mA or 0-10VDC.
    • Installation: Best performance is achieved by pairing with spherical washers to align forces. 
    Medical/Biological Applications 
    • Mitral/Aortic Valve Studies: Specialized miniature force transducers have been developed to measure the dynamic forces of the mitral or aortic annulus in animal models, aiding in the development of repair devices.
    • In-vivo Monitoring: These devices are implanted to measure forces like septal-lateral contraction, often requiring precise, non-elastic suturing to ensure accurate force measurement. 
    Common Uses 
    • Crane overload protection
    • Bolt tension and fastening systems
    • Industrial press tools
    • Force measurement in surgical research

    Can strain gauges measure force?
    Strain gages can be used to measure force, as in Figure 4.6 where a cantilever beam is slightly deflected by the applied force. Four strain gages are used to measure the flex of the beam, two on the top side, and two on the bottom side. The gages are connected in an all-element bridge configuration.
