Ultrasonic Leak Detector SL 3000 Trotec – Air, Gas and Vacuum

SL 3000 Ultrasonic Leak Detector – TROTEC

The SL 3000 is a professional tool designed to quickly detect leaks and sealing defects in compressed air, gas, steam, or vacuum systems.

Compact and robust, it converts the ultrasound generated by leaks into easy-to-interpret visual and audible signals. Every repaired leak helps reduce energy losses, often estimated between 30 and 40% of total compressed air consumption.

An ally for preventive maintenance

Beyond leak detection, the SL 3000 proves particularly effective for the early diagnosis of rotating machinery. It detects early signs of bearing wear, cavitation issues on pumps, or anomalies on steam traps, without production interruption. The device also allows identification of partial electrical discharges related to insulation faults.

Ergonomics and ease of use

The SL 3000 requires neither lengthy training nor complex procedures. Its measurements rely on a high-performance acoustic transducer that makes ultrasound audible through the isolating stereo headset and visible on a backlit display. Results are displayed simultaneously in analog and digital modes. Its compact design facilitates field transport, even in demanding industrial environments.

Interchangeable probes for every application

The SL 3000 adapts to multiple uses thanks to a wide choice of probes:

Airborne noise probe for detecting compressed air or gas leaks within a 3 m radius

Acoustic horn (included) to extend detection range up to 8 m

Directing tube with tip for precisely targeting a leak while isolating background noise

Goose neck probe (optional) for inspecting hard-to-reach areas

Parabolic probe (optional) for locating leaks or partial discharges up to 20 m away

Structure-borne noise probes for analyzing the mechanical condition of machines and checking valves, gates, or steam traps like an electronic stethoscope

Building leak tightness checks

Combined with an ultrasonic transmitter, the SL 3000 allows testing for air leaks in windows, doors, cabins, or climate-controlled enclosures. The emitted ultrasound escapes through non-sealed points and is immediately detected by the device.

Practical advantages of the SL 3000

Compact and robust device, IP54 protected
