Prokhorov N. L., Reizman Ya. A., Ostrovsky M. A. Channels, contours, systems: human factor and new tools for reliable solutions
The paper considers the inheritance of human factor by an automation system and its influence Ė a problem associated with the development and growth of control systems. From the viewpoint well-known principles, it discusses the limits of existing solutionsí capabilities and promising approaches to this problem at all levels and in various aspects of automation systems. The implementation of the approaches presented is illustrated with the second generation of SM hardware and toolkits.
Reizman Ya. A., Ostrovsky M. A., Krasovsky V. E. Intelligent sensors: new development tools and the new level of field automation
The paper discusses how end users and vendors can benefit from building the ďintelligenceĒ into the bottom level components of field instrumentation (sensors and actuators). Various aspects of the development undertaken within existing technologies are considered. Key elements of SM9107 technology created in the Institute of Control Computers are outlines. The technology enables significant costs reduction in intelligent sensor development and, first of all, the elimination of professional programmer from the design process.

Buryachenko A. G., Ranchenko G. S., Chivers J. Vibration-compensated high-temperature variable pressure sensor for low-emission gas turbine engines
The paper discusses the compensation of pressure sensorsí additional error due to vibration (linear) acceleration. The topicality of these issues in sensor selection for variable pressure measurement in combustion chambers of low-emission gas turbine engines is shown and key requirements to such sensors are formulated. A vibration-compensated (g-insensitive) sensing device and a transmitter based on it are described. Basic results of new sensorís field tests within a gas turbine engine are included.

Metran industrial group presents Metran-150 new pressure sensor. This next generation device provides the performance meeting today requirements and enable significant improvement of process operation reliability and product quality in power engineering, chemistry, oil and gas industries.
Granovsky V. A., Siraya T. N. Model validity in measurements
The problem of model validity with reference to measurement as a complex system is discussed. The significance of this problem in metrology is caused by the fact that the estimates of the measurand and the errors are obtained within the accepted model. The paper outlines the key issues of the problem including the validity in narrow and broad sense, formal and physical adequacy. The problemís origins and model verification principles are analyzed. The validity is investigated with reference to the full range of models for measurement elements and phases. The validity aspects related with the measurand and measurement errors are emphasized as the most significant ones. The paper concludes that the validity indicators should be included into metrological performance, while the validation procedures should be regulated as other procedures in metrology.
