Intelligent Sensor for Measurement Systems with Sinusoidal Excitation Response

Measuring devices and systems containing sensors that require sinusoidal excitation are widely used in information measurement technology both production conditions research practice. Examples include various types of metal detectors, eddy current flaw analyzers liquid media, electrometers with a dynamic capacitor, etc. The aim the work was to develop optimal architecture algorithms for operation intelligent intended use measuring operating according – response scheme. This paper describes approach proposed by authors construction based on modern microcontrollers, distinctive feature which is continuous generation reading responses background, as well setting readiness flags data processing main process microprocessor, ensures uninterrupted execution background processes, excitatory action. has been tested development charge-sensitive surface mapping systems, such Kelvin probe vibrating photo voltage case semiconductors.
