The deposition rates of protective coatings resembling polydimethylsiloxane (PDMS) were measured with numerous sensors placed at different positions on the walls of a plasma-enhanced chemical vapor deposition (PECVD) reactor with a volume of approximately 5 m3. The plasma was maintained Read More …
Silicon avalanche photodiodes (APDs) are designed predominantly for high-speed communication applications, but they can also offer interesting low-light application solutions in lower frequency bands. The design and analysis of a high sensitive silicon avalanche photodiode (APD) receiver for low-light fiber-optical Read More …
An industrial size plasma reactor of 5 m3 volume was used to study the deposition of silica-like coatings by the plasma-enhanced chemical vapor deposition (PECVD) method. The plasma was sustained by an asymmetrical capacitively coupled radio-frequency discharge at a frequency Read More …
A new level measurement method based on the onedimensional (1-D) acoustics gas resonator is presented. The proposed method has been investigated in detail, and experimental gauges have been built and tested under artificially induced residues, foams and deposits. The level Read More …
A new level-measurement method is presented. It is based on the acoustic resonance of a waveguide. This method can be successfully implemented for fluid-level measurements in industrial plants, where problems of residues, deposits, foams, etc., can be expected. An experimental Read More …

This paper presents concept and design of a miniature liquid level gauge. An experimental level gauge with the measurement range of 5 cm, relative accuracy better than 0.5% and resolution better than 0.1%, has been demonstrated in practice. The proposed Read More …
This paper describes a novel electrically passive fluid level gauge. It is based on a one-dimensional low-frequency acoustic gas resonator. The acoustical power is delivered to the resonator an the acoustic waveguide and a fibre-optic microphone is used as an Read More …
