Ultrasonic cleaning is now a well-established technique in many industrial applications including oil and gas which are possibly the most challenging conditions of all. To keep optical sensor windows clean usually requires very high energy, but deploying such high levels of energy has its own risks and is regularly problematic for the physical instrument and the sensor window, often eroding and cracking, not only the optical windows, but the physical housing of the sensor itself.
Inov8 Systems have developed a solution improving the efficiency of the ultrasonics and reducing the typical power required by up to 88%. In doing so the sonic shock and cavitation erosion is eradicated, hugely reducing the chances of sensor window and housing damage. A further benefit of improving the ultrasonic efficiency is the ability to control and focus the ultrasonics to achieve cleaning in 0.2 seconds with low power, removing heavy oils and allowing the unit to be powered by 24VDC and even a solar panel.
