best ultrasound detectors in the world, but
we’re more than just an innovative tool
manufacturer. We are the ultrasound
experts, and we want to help your team
build and sustain a world-class ultrasound
program, specific to your organization’s
needs.

The UL101
CBM Kit

The CTRL UL101 CBM Kit converts ultrasound signals produced by industrial machinery and vehicles into easily recognizable audible sounds so the user can evaluate the condition of individual components, even in extremely noisy plant environments. The CTRL UL101 is used worldwide for predictive maintenance, quality control, and for leak detection.

The Benefits

Key Features

Fixed Frequency

High Sensitivity to all turbulent flow air, gas, or vacuum leaks

Easily adjustable sensitivity and gain

Lightweight, one-handed operation

Converts ultrasound to easily recognizable audible sounds

How It Works

Using ultrasound detectors for leak detection is a growing industry standard. Acoustic ultrasound leak detection is recommended by many, such as the U.S. Department of Energy, as the best method for detecting the location of leaks in order to minimize energy waste and improve plant efficiency.

The CTRL UL101 Leak Detector converts the ultrasound (40 kHz +/- 1 kHz) down into the audible range and outputs to a headset. All other frequencies are filtered, so that even the smallest air/gas, vacuum, or refrigerant leak can be detected and pinpointed in a noisy plant environment.
