Leak Detection & Noise Monitoring

\If gases escape through leaks in pressurized pipe systems (e.g. non-tight screwed connections, corrosion and so on), ultrasonic noises are generated. By means of LD 450, even the smallest leakages which cannot be heard by the human ear and which are not visible due to their size can be detected even from distances of several meters. LD 450 transforms the inaudible signals into a frequency which can be identified by human beings. By means of the comfortable soundproof headset, these noises can be detected even in extremely noisy environments.  

The LD 450 leak detector is the advancement of the proven LD 300 and LD 400 and it impresses with its significantly refined sensor technology and its improved support in the tracing of leaks. By means of the integrated laser pointer, which serves for target heading, the leak can be localized more accurately. Through the use of a specially designed acoustic trumpet, a better bundling of the sound waves is achieved. This trumpet acts like a directional microphone, which bundles ultrasonic waves and thus improves the acoustic behavior. Due to the special design of the acoustic trumpet, the use of the laser pointer is not hindered.  

The LD 450 meets the requirements of Class I instruments for the norm "Standard Test Method for Leaks with Ultrasound" (ASTM Int. - E1002-05).  

Typical Applications:

Leak detection on:  

- Compressed air, gas and vacuum systems

The new leak meters LD 500/510 with integrated camera and leakage calculation are ideal measuring instruments that help to find and document even the smallest leakages (0.1 l/min corresponds to approx. €1 p.a.) easily, even at far distances. The LD 510 is the world’s first leak meter with an additional freely assignable sensor input for all CS sensors. In addition to leakage measurement and detection, all necessary measurements with regard to dew point, flow, pressure, and temperature can also be carried out.

Special features of leak detector LD 500/LD 510:

•  Determine leak size (l/min) and potential savings (€/year)
• Detect the smallest leaks at long distances
•  Auto level: automatically adapts sensitivity to the environment and reliably eliminates ambient noise
•  Capture photographs of leaking parts
•  Add descriptions of leaks and necessary actions
•  Transmit leak details via USB to desktop software or via Bluetooth to the app
• Generate an ISO 50001 report
•  Continuous leak detection for up to 9 hours
•  Additional sensor input for CS Instruments sensors (LD 510 only)

Optional accessories for easy localization of leaks:

Detecting compressed air and gas leaks can be challenging depending on the accessibility of the systems. To address this, special accessories are available for the LD 500/510 leak detectors to facilitate leak detection in hard-to-access areas.

These include a special acoustic trumpet, a focus tube with focus tip, a flexible gooseneck, and a parabolic mirror. For more information, please see the additional product images on the left.

The mobile Ultrasound Viewer benefits from exclusive technologies from ACB Engineering, specialists in sound cameras for over 20 years. Using the latest video techniques, the MUV is fully automatic—you just have to turn it on and watch where the ultrasound spot is superimposed on the video. The localization accuracy is on the order of one centimeter when the measurement is close and a few centimeters when the measurement is farther away, regardless of the origin of the ultrasounds (leaks, rolling, arcs, etc.). It is possible to record pictures or videos to communicate easily with others.

When powerful performance is needed and budgets are limited, choose the versatile Superior AccuTrak® VPE-1000 Ultrasonic Leak Detector. It is the first low-cost digital ultrasonic leak detector, offering extraordinary features at a fraction of the cost of other ultrasonic instruments. The versatile AccuTrak® VPE-1000 features separate ultra-sensitive sensors for both airborne and contact ultrasound. Extremely sensitive to the ultrasonic sound of leaks and friction in industrial systems, the VPE-1000 Ultrasonic Leak Detector uses a technique called "heterodyning" to translate ultrasound to a lower frequency which our ears can interpret. AccuTrak® Ultrasonic Leak Detectors are so sensitive they can hear the blink of an eye, yet most background noise will not interfere with leak detection accuracy. Patented technology uses a microcomputer and digital circuitry, making the AccuTrak® VPE-1000 the most accurate and repeatable ultrasonic leak detector available in its class.

The optical head houses a near-infrared laser diode with a built-in high-speed photodetector, an acousto-optic modulator, and a red laser diode for precise beam aiming.The controller includes a demodulator, signal strength indicator, two selectable velocity ranges, and a set of low-pass filter options.

CS INSTRUMENTS has been a leading global manufacturer of measurement technology for compressed air and gases for more than 20 years. Many years of feedback and experience from several thousand satisfied customers of the previous 300/400/450/500 series leak detectors have been incorporated into the development and research of the LeakCam 600.

Unlike many other manufacturers, CS INSTRUMENTS also has calibration stands and flow meters for precise consumption measurement and leakage measurement of compressed air and gases. This know-how, coupled with over 20 years of experience in the development of leak detectors, has gone into the development of the LeakCam 600.

During development, particular attention was paid to practicality and user-friendliness. What does it really mean for the service technician or maintenance engineer to search for and document gas leaks and compressed air leaks in the production process with a leakage camera in their hand for 8 hours, for example?

Unlike many other leakage cameras, the LC 600 was developed with these points in mind, such as:

The unique integrated laser distance measurement automatically calculates the distance to the leak. There is no need for time-consuming and incorrect distance measurement as with other devices. Precise measurement of the distance to the leak is the most important parameter for accurate leakage calculation.

Superior Signal Company is proud to announce the latest version of our most popular ultrasonic leak detector – the 3rd generation AccuTrak® VPE. Featuring all-new internal circuitry, the improved AccuTrak® VPE stands out above all other ultrasonic leak detectors in its class. With even greater sensitivity and a number of new features unique to the VPE, no competitive ultrasonic leak detectors come close.The patented Superior AccuTrak® VPE Ultrasonic Leak Detector is a state-of-the-art, non-invasive ultrasonic leak detector that can detect both pressure and vacuum leaks of any gas. The AccuTrak® VPE is ideal for pinpointing leaks in air conditioning, refrigeration, automotive, and other systems. AccuTrak® Ultrasonic Leak Detectors are extremely sensitive to the ultrasonic sound of a turbulent gas leak. Using a technology called "heterodyning," they translate ultrasound to a lower frequency that your ear can interpret. AccuTrak® Ultrasonic Leak Detectors maintain the original sound characteristics of the ultrasound, making it possible to distinguish leaks from other competing background sounds. AccuTrak® instruments are so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy.

The Superior AccuTrak® VPE-2000 Ultrasonic Leak Detector is the first digitally controlled ultrasonic leak detector. Like two instruments in one, it uses two independent sensors supported by separate electronic circuits configured specifically to their own sensor. This assures optimum sound clarity and frequency response. When switching between the airborne and contact sensors, all settings are retained in memory! Digital LED meters let you establish baselines, perform trending, and accurately repeat these tests better than older, more expensive analog instruments.
