Study for Initial Load Effects on the Calibration of Load Cells

Abstract

<jats:p>This work was carried out by the National Institute of Standards NIS), Egypt, as a result of experimental cases in load cell applications. The aim of this study is to compare the behavior of load cell works under initial load with the ideal working case. The study was carried out using seven load cells from different manufacturers and with different types, capacities, working modes and classes. As a result of the behavior of the load cells during this study; it is clear that the response of the load cells previously loaded against applied load differ from the ideal case. Load cell operators have to carry out mathematical calculations to correct the reading rather than using electrical methods to readjust the zero signal and neglecting the initial applied load.</jats:p>

Analysis of modern measuring instruments for research diagnostic systems of print media equipment

“…In the LabVIEW program, a scheme was drawn up for collecting data from a strain gauge and an accelerometer [25]. To smooth the received signals from the sensors, the scheme provides a smoothing filter with a rectangular window with a half-width of five measurements.…”

“…Thus, one volt corresponds to 48,8 m/s 2 . To collect data, we used an NI cDAQ-9178 unit from National Instruments, connected to a personal computer with the LabVIEW 8.2 program.In the LabVIEW program, a scheme was drawn up for collecting data from a strain gauge and an accelerometer[25].
