In this paper we present a radio frequency precision sensor on rectangular spirals with the opposite direction of winding. The sensor is purposed to control and measure the gap to a flat metal surface. The sensor model was created using CST Studio Suite software. Using this model, we obtained relation between the gap width and change of electrodynamic parameters of the sensor. A schematic diagram of the sensor's measuring generator based on a modification of the Colpitts LC-generator was developed, and its characteristics were obtained in the PSpice. This paper also indicates the advantages of using proposed sensor as a base for various devices and systems for monitoring, measurement and controlling of physical quantities and parameters of technological processes.
