Our Hydro Sensors record multiple variables – not just one – so that you can obtain a more accurate understanding of your machinery’s vibration issues. In short: you need real time monitoring to get real, usable data. Air gap dimensions along with rotor and stator shape cannot be effectively measured with the generator out of service because of the combined effects of centrifugal, thermal, and magnetic forces. Our 4000 series capacitive generator air gap sensor sets the standard for real-time air gap measurement between your generator’s rotor and stator – vital if you want to understand your unit’s behavior under load. We at Bently Nevada pioneered this space over 50 years ago with the launch of our eddy current proximity transducers to which have been added dynamic pressure, generator air gap, and stator end winding vibrations. When you need to know what’s going on with your hydroelectric generator – especially while it’s in operation – Bently Nevada† has you covered with our family of proven Hydro Sensors.
