Hear What Thermal Imaging Can't — Precision Ultrasonic Diagnostics
Ultrasonic testing detects compressed air leaks, electrical corona discharge, and bearing wear that generates no visible heat signature — complementing infrared thermography for a complete predictive maintenance program.
What Is Ultrasonic Testing?
Ultrasonic testing uses specialized equipment to detect high-frequency sound emissions (typically 38–40 kHz) that are inaudible to the human ear but are produced by turbulent fluid flow, electrical discharge, and mechanical friction. When compressed air escapes through a leak, when an electrical component generates corona discharge, or when a bearing begins to wear abnormally, these events produce characteristic ultrasonic signatures that can be detected, quantified, and documented.
Invizions uses state-of-the-art Fluke ultrasonic instruments to conduct surveys that complement infrared thermography inspections. The combination of thermal imaging and ultrasonic testing provides a more complete picture of equipment health than either technology alone — a best-practice approach recommended by NFPA 70B and leading predictive maintenance authorities.

Compressed Air Loss Detection
Compressed air is one of the most expensive utilities in an industrial facility — and also one of the most commonly wasted. Industry studies estimate that the average industrial plant loses 20–30% of its compressed air through undetected leaks. Ultrasonic testing locates leaks in compressed air lines, fittings, couplings, valves, and pressure vessels quickly and non-invasively, even in noisy industrial environments.
- Compressed air and gas distribution lines
- Pneumatic fittings, couplings, and unions
- Pressure regulators and control valves
- Compressed gas vessels and storage tanks
- Steam trap surveying

Partial Discharge & Corona Detection
Electrical corona and partial discharge produce ultrasonic emissions that precede visible arcing, insulation breakdown, and catastrophic failure. Detecting these signatures early — while equipment is still operating — allows planned maintenance rather than emergency repairs. Ultrasonic electrical surveys are particularly valuable in switchgear, transformers, bus ducts, and high-voltage distribution equipment.
- Switchgear and motor control centers
- High-voltage cables and bus ducts
- Transformer bushings and insulators
- Overhead distribution lines
- Indoor and outdoor electrical enclosures

Bearing & Mechanical Inspection
Failing bearings generate characteristic ultrasonic signatures before they generate detectable heat or vibration. Ultrasonic bearing inspection provides the earliest possible warning of lubrication failure, contamination, wear, and impending seizure. Results can be trended over time to track bearing degradation and plan lubrication or replacement at the optimal interval.

A single compressed air leak survey typically pays for itself within weeks. A bearing that fails without warning can cost tens of thousands of dollars in emergency repairs, lost production, and secondary damage — while ultrasonic detection of the same bearing might cost a fraction of that. Invizions provides detailed survey reports that quantify leak costs and prioritize repairs by severity.
