Design and testing of a thick-film dual-modality sensor for composition measurements in heterogeneous mixtures

Abstract: The current paper focuses on design and laboratory evaluation of a dual-modality sensor, developed for the needs of oil and gas extraction industry to measure the composition of heterogeneous mixtures in harsh conditions. The sensor combines ultrasonic and electrical measurement techniques, which are non-destructive, rapid and can potentially provide an on-line industrial measurement. Such a 'dual-modality' measurement could potentially be reliable in a wider range of process conditions. A distinct feature of … Show more

“…It is believed that the size and the material characteristics of such sensors may be beneficial for constructing slim-line and robust probes, or sensors which can be potentially easily embedded and distributed within the process environment-in particular, within the oil and gas extraction plant, which was envisaged as the main application area. The design philosophy behind these sensors and the detailed design and fabrication procedures were already reported in [1] and will not be repeated here.…”

“…In brief, the fabrication of thick-film sensors involves successive screen-printing and high temperature firing of thick-film pastes [1]. These form a multilayer sandwich of two metallic electrodes (each around 10 m thick) with piezo-ceramic material (about 50 m thick) placed in between the electrodes, deposited on an alumina substrate.…”
