Ultrasound is a game-changing technology, especially when combined with standard vibration output. Ultrasound technology works by attenuating a resonance at a high frequency with a curve to a resonant peak at an even higher frequency. An ultrasound output allows users to be alerted for early bearing fault detection and to monitor the lubrication levels inside the bearing housings.
CTC's UEB/UEA Series of Dynamic IEPE Vibration & Ultrasound Accelerometers series have a linear vibration output of 0.5 Hz - 23 kHz within a ± 3 dB tolerance. The resonant peak of this sensor is 42 kHz, which allows this one sensor to give a premium output in the vibration range and the ultrasound range. You no longer have to use two different devices to achieve both methods of monitoring, only one!
