Ultrasonic Detector

HNL Systems Pvt Ltd offers an Ultrasonic Detector, Model USL-200, with dual frequency band for critical applications with noisy background such as compressor rooms, textile mills and other industrial environments. When air or gases escape through leaks, ultrasonic noises are generated. By using USL detectors leakages in the ultrasonic range can be detected even from distances of several metres. The use of USL series detectors for regular inspection of engines, pumps, steam traps, etc., for detecting and preventing leaks guarantees a longer operational life of the machinery. US-series ultrasonic detectors work by detecting and converting the high frequency sound associated with turbulence, friction and arcing in industrial and commercial systems down to the audible range where they can be heard in the headset and viewed on the meter. Translation is done by Hetrodyning, i.e., comparing the incoming signal with the one that is generated by the meter. USL-200 is most sensitive to sounds around 40 kHz and 30 kHz while USL-100 is most sensitive at 40 kHz, that's twice the frequency of the best human hearing. Because USL series is focused on a specific band, sounds from wind, traffic, etc., will not be detected. Exact frequency focus allows for precise leak detection and nearing defect discovery. An optional efficient integrated data logger enables the rapid transfer of data between the device and the computer via a USB interface. The optional ultrasonic transmitter can be used to detect leaks in systems at ambient pressure like vehicles, freight containers, and ventilations, where no ultrasound is generated. The transmitter generates ultrasonic waves which emerge from the leaks, are detected from outside with USL detectors. The company also offers Ultrasonic Leak Detector & Inspection Systems and Ultrasonic Detector, USL-100.
