An acoustic horn has been developed for Sasol Synfuels in Secunda. It has been concluded that this is the best methodology for dislodging ash agglomeration on the boiler tubes, since it can perform this act while boilers are in operation, thereby eliminating the need to shut down boilers for cleaning. The acoustic horn utilises sound energy that induces vibration and strain on the boiler substructure components. This results in a concern to develop vibration and strain sensors in order to measure these phenomena. An accelerometer is considered to monitor vibration signals, while a secondary strain-gauge sensor is considered to measure strain signals. The analysis entails a predetermined assessment of the suitable sensor parameters for the anticipated input signals. The appropriate accelerometer for this kind of application is concluded to be a piezoelectric accelerometer with a sensitivity of 1000 mV/G as most suitable. Furthermore, a strain-gauge sensor of a quarter-bridge type one with a gauge factor of 2 and nominal resistance of 350 Ω is deemed to be most suitable.

“…Vibration is a common phenomenon in various mechanical systems and structures, ranging from rotating machinery like motors, pumps, and turbines to bridges, buildings, and vehicles [1][2][3]. When a mechanical system operates, it generates vibrations because of imbalances, misalignments, wear, resonance, structural weaknesses, or other mechanical faults [4][5][6][7].…”

The ability to interpret vibration signals in the biomedical field offers a promising path toward continuous improvement of medical devices. By examining the revolutions per minute profile, analysts can identify any deviations or anomalies in the vibration patterns at different speeds. This information can help identify potential faults or imbalances within the rotating machinery. With a comprehensive understanding of the revolutions per minute profile, analysts can make informed decisions regarding maintenance and repairs. Besides, the analysis of the order of vibration signals represents an essential pillar of biomedical engineering, bringing an innovative and in-depth perspective to the development of medical devices, and contributing to the continued advancement of medical technology and healthcare. Integrating vibration analysis into preventive maintenance practices can help ensure the reliability of medical equipment, reduce potential risks to patients, and contribute to the advancement of healthcare quality.

In this study, piezoelectric based compressive type accelerometer has been de-signed by using PZT-5A ceramics with bellewasher type spring. FEA analysis were carried out by using COMSOL. According to COMSOL simulation, reso-nance frequency is nearly 42500 Hz. Sensitivity of the designed sensors were measured and compared each other. Frequency spectrum was between 100Hz-10 kHz. The effects of piezodisk thickness, stiffness of the spring and seismic mass on the sensitivity of the designed sensor were investigated. Voltage output is in-creasing from 4.1 mV/g to 12.7 mV/g while seismic mass is raised from 3 gr to 10 gr. Linearity depending on the frequency of the designed accelerometer was dis-torted above 5.5 kHz like commercial accelerometer. In addition, real-time tests were performed using a calibrated accelerometer and a designed accelerometer on the internal combustion engine and drivetrain. Vibration profiles were carried out randomly. According to the results obtained here, it is observed that all the peaks were matched with a coefficient about 1.3.
