E Permana, Yayat Yayat · IOP Conference Series Materials Science and Engineering · 2018
The purpose of this research is to produce an impact load sensor - a laboratory dynamic testing equipment that fulfills good criteria for education purposes and real time impact load measurement in actual conditions. For this purpose, a force transducer with 4-gauge system was used. A performance of the sensor was evaluated by considering static characteristics of the sensor exhibited upon applying static load and dynamic load of maximum 10 kN. Experimental tests were performed on a blank of aluminum Al601-T6 and strain gauges configured with Full-Wheatstone bridge system and held in the Dynamic Laboratory, Indonesia University of Education (UPI) Bandung. The experimental tests showed that the static characteristics of the sensor indicating its promising performance. The accuracy, linearity, and repeatability in static and dynamic load measurements showed error values bellows ± 3 % f.s. (full-scale reading). Those meet with specifications expected in the research design.
