An Aerospace Company was working on a test plan that involved taking torque & compression measurements on fasteners with varying joint materials. The system required both high and low sampling rates, in addition to the capability of precisely measuring force and torque simultaneously. They required reliable accuracy and long-term stability. The test plan intended to provide verification of required force and torque specifications for fasteners, to ensure safety without compromising installation.
Using a Model LW or LWCF Load Washer in conjunction with a Model T12 Square Drive Rotary Torque Transducer, the customer was able to align force and torque measurements to desired levels. This was accomplished by combining the sensors with the high sample rate of the data logging and graphing capabilities of the SI-USB, capturing real-time force and torque levels for examination.
The fasteners were tightened to the specified force and torque requirements and were safely installed without impairment to themselves or the joint material. The customer was able to measure the rapid event effectively and accurately.
