Ways of solving the rotary machines intelligent vibration sensors increasing the temperature stability problem using piezoelectric accelerometers are considered. A method is proposed for increasing the vibration measurement accuracy by determining the piezoelectric accelerometer conversion coefficient current value without dismantling it from the operating object and without taking the rotary machine out of the operating mode. An algorithm for implementing the method in a digital vibration monitoring system intelligent sensor is described. The experimental studies results are presented, showing that the proposed method use can significantly reduce the additional temperature error in measuring the turbine units vibration parameters and other rotary machines. # CSOC1120.

This article deals with the development of tools for configuring and modeling modular information and measurement systems. The use of standard solutions for the industrial facilities automation requires the use of special tools–configurators. It is advisable to use one of the popular CAD systems, for example, AutoCAD, as the basis for creating the configurator. Authors analyse various ways for creating and managing AutoCAD projects using built-in tools and external programs. It is shown that ObjectARX environment is the most powerful means of solving such problems, providing maximum integration and performance. The results obtained by the authors during the modular systems configurator development allow recommending ObjectARX for creation of specialized CAD systems based on AutoCAD.
