Detect Ultrasound in Real Time

Non-intrusive & Earliest failure warning

High sensitivity

EMI/RFI Protection

Our Acoustic Energy sensor is designed with Predictive Maintenance in mind


✽ Very effective: Detects the internal material stress, producing the earliest warning before the failure happens.

✽ Accurate: Ambient noise and vibration do not affect the ultrasonic readings.

✽ Smart: Featuring ALTERIA's embedded pre-processing technology. Saving 93% of the data payload at the output.

✽ Easy to use: Forwards data through an industrial wireless system or serial port.

✽ Non-intrusive: No installation. Just secure the sensor with adhesive to the machinery.

✽ Reliable: Built with top quality parts manufactured in the United States and Europe.


The UD 103 is a real revolution in the field of predictive maintenance, using patent pending technology by ALTERIA.

The analysis of acoustic energy is a very powerful tool to analyze the condition of machinery across many industries and infrastructure as:

- Power distribution and high voltage
- Pneumatic machinery
- Rotating machinery
- Power electronics, VFD drives
- Aerospace: pressurization leaks
- Gearbox and bearing maintenance

The UD 103 is smart sensor that forwards simplified pre-processed data such as the frequency of each acoustic energy peak, the bandwidth, amplitude, background noise etc, in order to save on resources in connectivity and data post-processing on the server side.
