Precision measurements of friction processes have a key role in a variety of industrial processes. The emergence of fine electronic circuit techniques greatly expands capabilities of control. There are some difficulties for their full implementation today, especially than it (which) regards the accuracy and frequency of measurements. The motion-measuring method in real-time system is considered in this article, especially accuracy increasing. This method is based on rapid analog digital converter (ADC), transmission program and digital signal processor (DSP) algorithms. Description of laboratory devices is included: Tribal-T and universal friction machine (MTU- 01) designed for “Pin on disc” tests. Great emphasis is placed on the usability of accelerometers. The present study examined collected data, via laboratory system for data acquisition and control, and it processing in the laboratory of Biotribology. Laboratory supervisory control and data acquisition (SCADA) algorithms is described below. Task of regulation is not intended. This paper describes only the methods of automatic control theory to analyze the frictional quality.
