General Information 0
Clevis Load Pins are strain gage transducers developed by Strainsert (U.S. Patent No. 3,695,096). They are manufacured utilizing the internal strain gage process perfected by Strainsert since 1960. We offer precision force measurement by simply replacing existing clevis pins.The design is a double-shear arrangement. Typically, force P is applied at the center of the pin while 2 equal opposing forces of P/2 are applied at each end. Strain gages are sealed inside a small axial hole and are positioned at the 2 shear locations at the interface between the center eye and clevis ends. The strain gages are positioned and oriented with great precision along the neutral plane relative to the specific direction of force. An anti-rotation device is necessary for proper reading and alignment. If a force P is applied to the pin at an angle other than the specified direction, the theoretical bridge output will be offset by a component of the force along the sensitive direction, i.e. P cos X.The four strain gages (two at each shear location) are electrically connected to form a full bridge, the signal from each gage being additive so that the bridge output is proportional to the sum of the forces transmitted by the shear planes of the pin. The circuit typically includes temperature compensation, signal trim (optional), and zero balance resistors terminating in a suitable connector socket or integral cable, and potted with a sealing compound inside the gage 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. Strainsert factory calibrations are intended to simulate installed conditions, however, it is recommended that an in-place calibration be performed to account for any installation, tolerance, and/or alignment influences affecting sensor measurement.Standard models are typically used in new applications where the designer can develop the specific load pin joint around the standard load pin dimensions, to optimize force measurement performance. In addition, the standard load pin may fit or can be incorporated through the use of bushings or modification of the assembly.Calibration data up to 500,000 lbs. Higher capacity calibration data is available at an additional charge. Inquire for custom product ranges.
