Compressed Gas & Vacuum Leak Detection

White Papers

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.

White Papers

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)

White Papers

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.
