Standard Force Sensing Load Pins/Bolts, CPA/CBA Series

The Force Sensing Clevis Pin or Clevis Bolt, otherwise known as load pins, are unique load sensors utilizing the internal strain gage transducer process developed by Strainsert and used also in their Flat Load Cells® and Tension Links. These load pins and clevis bolts offer precision force measurement by replacing existing shear pins, clevis bolts, load pins, shear axles and many other types of pinned joints for the aerospace, automotive, marine and military industries.

Features:

The Strain gauges are sealed inside small axial holes within the load pin and are positioned at two locations at the Clevis to Clevis Eye interfaces. In order to sense only those strains which are induced by the shear forces at these two sections, the strain gauges are positioned and oriented with great precision, at a neutral plane relative to one specific direction of pin loading.

The four strain gauges (two at each location) are electrically connected to form a full bridge, the signal from each strain gauge being additive so that the bridge output is proportional to the sum of the loads transmitted by the shear planes of the pin. The circuit typically includes temperature compensating, signal trim (optional) and balance resistors terminating in suitable connector socket or integral cable, and potted with a sealing compound inside the gauge hole for enhanced environmental protection.

Standard models include detailed calibration data up to 500,000 lbs. Higher capacity calibration data is available at an additional charge. In-place calibration check is recommended.

Some Features Include:

  • Precision Load Sensing
  • Easy Installation
  • Rugged
  • Direct Force Measurement
  • Internally Sealed Strain Gauges
  • High Strength Stainless Steel

Applications

These standard clevis pins are typically used in new applications where the designer can develop the specific load pin joint around the standard clevis pin dimensions, to optimize force measurement performance. In addition, for existing load pin joints, the standard clevis pin may fit or can be incorporated through the use of bushings or modifying the clevis assembly. For information on custom designs.
