Compressed Gas & Vacuum Leak Detection
Increasing Personal Safety Using Airborne Ultrasound Inspection
Using ultrasound listening devices (ULDs) to detect toxic gas leaks, electrical faults, etc.
Non-Pressurized Cabin Testing
Using an Ultrasound Listening Device (ULD) and Ultrasonic Transmitter to leak test non-pressurized spaces.
Pinpointing Leaks in Re-Heaters
A routine leak detection program using ultrasound can be implemented to avoid unscheduled downtime of re-heater and boiler tube failures.
Ultrasound Leak Detection for Power Generation Condensers
Using an ultrasound listening device (ULD), improve power generation efficiency and output to keep up with the growing demands of electricity usage.
Why 40 kHz?
The 40 kHz transducer was selected for the UL101 and most other airborne ultrasonic sensors because it is ideal for detecting gas leaks from a reasonable distance and for diagnosing mechanical components for early signs of wear or defects.

Adopting ISO 2981-1 for Electrical Failure Diagnosis
Spectral Analysis of Airborne Ultrasound based on ISO 29281-1 recommendations.
InCTRL to Document Electrical Faults in Distribution Lines
InCTRL can help inspectors develop a system to detect CBM electrical failures in transformers, notify administration of the findings, and document repairs.
Partial Discharge (PD) Detection Using Acoustic Ultrasound
Partial discharges are harmful electrical discharges in electrical systems. The UL101 provides an acoustic ultrasound solution to detect these discharges.
Ultrasound Listening Device (ULD) Benchmarking on Electrical Facilities
CTRL's ultrasound listening devices and InCTRL platform are easy to implement and can help you save on workforce and diagnostic time
Sound Solution 13 - Electrical Tracking
Lubrication & Mechanical Condition-Based Monitoring (CBM)
More Than a Leak Detector
Ultrasound listening devices (ULDs) are capable of much more than leak detection.
Precise Lubrication with InCTRL
The use of the InCTRL platform will help the user not only determine the severity of an abnormality, but will also provide a practical way to report findings on routinely inspected bearings.
Ultrasound Condition-Based Monitoring
The InCTRL database management platform can be used to develop a full-scale, turnkey predictive condition-based process for manufacturing and industry.
