A new technology that uses airborne ultrasonic sensors to detect anomalies in the sounds machines make while running is already saving power companies hundreds of thousands of dollars by preventing unpredicted downtime.

Unlike other acoustics-based maintenance solutions, which either call for technicians to go from machine to machine, sampling and diagnosing problems, or require complex integrations, training and retrofitting of old industrial assets, Israeli start-up 3D Signals’ system allows for accurate and reliable coverage of a wide variety of equipment with a small number of cheap sensors.

As the company’s co-founder and CEO, engineer Amnon Shenfield, summarises: “Energy production must operate reliably in dynamic demand conditions, and we help guarantee that equipment runs smoothly while maintenance technicians and engineers can focus solely on the machinery that needs it most and not waste valuable time and resources conducting unnecessary inspection and maintenance on healthy equipment.”
