UL101
ULTRASOUND DETECTOR
The CTRL UL101 detects and converts ultrasound
produced by mechanical, pneumatic, hydraulic, and
electrical systems. Changes in the amplitude and
characteristics of the ultrasound are easily detected in
noisy plant environments. Leaks are easily pinpointed.
Equipment problems are diagnosed even earlier than
other technologies such as vibration, infrared inspection,
or oil analysis.
Benefits of UL101 Acoustic Ultrasound Listening Devices
Ease-of-use
Simply adjust the sensitivity on the UL101 Ultrasound Detector's handheld receiver to pinpoint the sound.
Directionality
Ultrasound stays very close to the source. Instantaneous results from condition-based monitoring, leak detection, valve diagnostics, and more benefit from this principle for troubleshooting.
Sensitivity
The UL101 Detectors is more sensitive than any detector on the market. Find the smallest leaks. Identify slow speed bearing problems easily, even below 10 rpms.
Costs
CTRL’s UL101 products are priced competitively compared to industry leaders, require less training, and are faster to use.
Applications
How the CTRL UL101 Ultrasound Detector Works
Using ultrasound detectors for condition-based monitoring and leak detection is a growing industry standard.
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.
