Abstract

The action of electrostatic converters is based on well known in physics phenomenon of electrostatic induction. A construction of converters may be various depending on properties of materials (structures) under investigation and on control or measurement objectives. Schematic diagrams of vibrating probe converter and capacity converter with linear varying voltage pulse source are presented in the paper and the main characteristics of converters are analyzed with consideration measurement timescale. Some experimental results are presented and discussed.
