Autors: Hristov, M. H. Title: Improvement Of Metrological Characteristics Of Air Gauge Systems For Linear Dimensions Keywords: air gauges, improvement, measurement systems, calibration, s Abstract: Air gauges (AGS) are widely applicable in series production and, in particular, in the automotive industry. Modern AGSs have more and more communication capabilities. Despite these improvements, some of their disadvantages remain unresolved - the need for calibration at start-up, the mistakes caused by supply pressure fluctuations, and the need for highly qualified staff. The advanced communication capabilities of AGSs for connection with PCs, computer based systems, PLCs, and others can greatly facilitate the calibration process while improving the metrological and operational performance of the systems. The current study presents the influential factors and methodology for improving the metrological and operational characteristics of AGS. These studies should facilitate the IPR calibration process by introducing software compensation. A one-off initial study of the instrument allows the introduction of software compensations for errors of non-linearity and supply pressure, which imp References
