SDT 150 ULTRASONIC SYSTEM
The compact hand-held SDT 150 ultrasonic system operates like an electronic stethoscope. It quickly pinpoints ultrasound originating from air, gas, liquid or vacuum leaks, or friction in moving parts and converts them to audible frequencies and an easy to read, numerical LED readout. Diagnosing system problems is faster, safer and easier. The SDT 150 will detect and locate ultrasounds even in a noisy environment (+80 dB), because it does not react to extraneous, audible noises. The SDT 150 system serves a wide variety of functions in plant operations, maintenance and quality control.
Operating frequency of 40 KHz SDT 150 operates in a frequency range that is best suited for a variety of industrial environments. Almost all ultrasounds caused by friction, pressurized leaks, and electrical arcs have peak outputs close to the 40 KHz range.
Excellent Signal to Noise Ratio The SDT 150 is not sensitive to the background noise, which interferes with obtaining a clear ultrasound signal. It detects and locates ultrasounds even in noisy environments.
Calibrated LED Display LED display reads out in decibels to make confirmation of findings easy among users of different skill levels and hearing capabilities.
Headphones The headphones block as much as 130 dB of background noise to better hear the ultrasounds and more effectively operate the detector.
Localization Extension Probe To distinguish between ultrasounds that are being emitted n close proximity, this probe narrows the signal field for better determining the sources of the ultrasounds.
Rechargeable Nicad Battery Unit includes a recharging connector to make recharging easy. Several Applications for SDT Ultrasonic Detection System
Early Warning of Bearing Failure Record baseline ultrasonic readings on critical bearings, motors, conveyors valves and other equipment. Trend the results automatically to determine when to lubricate and/or replace components before they fail!
More Effective Lubrication The SDT 150 can detect when a bearing needs lubrication, as well as when it is over lubricated by observing the noise level of the bearing. While applying lubricant, use it to determine when the grease reaches and quiets the bearing prior to over greasing.
Diagnose Valve Failure Some common problems with valves, such as internal leaks or blockage can be confidently diagnosed. Healthy valves read very quiet while a 'leaker' will emit turbulent noise in the 35+ KHz range. Since this unit only detects high frequency ultrasound, valves can be checked while in service, even in a very noisy environment.
Verify the Condition of Steam Traps Using the SDT 150 with the contact probe, the opening and closing of steam are verified. All types of steam traps are monitored using ultrasound technology because it is fast, effective, non-intrusive, and requires very little training.
Detect Compressed Air and Gas Leaks Compressed air and gas leaks create ultrasonic turbulence when they pass from the pressurized side across the leak orifice to the non-pressurized side (atmosphere). Using the SDT 150, scan along the pipe until the characteristic hissing sound is heard in the headset. With the rubber location probe in place, the leak is pinpointed quickly even in noise environments.
