Ultrasonic monitoring

Make early high-frequency change easier to act on.

ConditionCore accepts readings from fixed ultrasonic sensors or handheld instruments, preserves the instrument, point, mounting or coupling method, frequency band, gain, filter, duration and operating state, then trends change against the correct reference.

Ultrasonic monitoring

High-frequency change needs a repeatable setup.

Keep the contact point, instrument settings and operating state attached to every comparison.

Preserve the setup before comparing high-frequency change.

Fixed and handheld readings can share a machine timeline without pretending their absolute levels are interchangeable.

Directional agreement can strengthen the case for follow-up. Absolute dB values remain tied to their instrument, gain, filter and contact method.

Data in

The context required for comparison.

Ultrasonic levels are instrument- and setup-dependent. Trends are comparable only when the instrument, gain, filter, method and location are controlled.

  • Fixed ultrasonic sensors
  • Handheld inspection readings
  • Demodulated audio or waveform
  • Instrument-referenced dB values
  • Gain, filter and duration
  • Point, mounting and coupling method

What it can reveal

What the measurement can support.

Friction change

Track high-frequency energy at a fixed point using a consistent acquisition setup.

Lubrication condition

Observe response to a controlled lubrication action without relying on level alone.

Repetitive impacts

Test demodulated impacts against configured bearing frequencies and machine speed.

Compressed-air leaks

Locate airborne ultrasonic sources and retain inspection context where applicable.

Steam-system leakage

Support targeted inspection of traps and valves using an appropriate procedure.

Electrical discharge

Surface patterns for qualified electrical inspection when the instrument and use case permit.

How ConditionCore uses it

From source data to a qualified observation.

Early friction, repeat impacts, lubrication response and leaks, trended with one controlled acquisition setup.

  1. Capture

    Accept a fixed-sensor stream or a documented handheld inspection reading.

  2. Normalize

    Retain instrument, gain, filter, contact method and point location.

  3. Trend

    Compare the same setup and operating state against its local reference.

  4. Correlate

    Relate friction or impact change to vibration, thermal and lubrication evidence.

Common questions

Ultrasonic monitoring, in practice.

See the controls required for a trustworthy comparison.

What does ultrasonic condition monitoring detect?

It can reveal high-frequency change associated with friction, lubrication condition, repetitive impacts and, in suitable applications, leaks or electrical discharge.

Can data come from fixed sensors and handheld instruments?

Yes. ConditionCore can retain fixed-sensor streams and documented handheld readings, including their different acquisition settings and references.

How should ultrasonic readings be trended?

Use the same measurement point, instrument or calibrated reference, gain, filter, method and sufficiently similar operating state. A dB value without that context is easy to misread.
