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.
