Originally designed for the US Military, the CTRL ULIOI Ultrasonic Inspection System is now used in several industries throughout the world for predictive maintenance, trouble-shooting, and leak detection.

The CTRL ULIOl Receiver converts ultrasound signals produced by industrial machinery and vehicles into easily recognizable audible sounds so the user can evaluate the condition of individual components, even in extremely noisy plant environments. Early warning signs and defects can be detected thus preventing costly repairs, safety-related injuries, and downtime.

• Unmatched sensitivity, signal­to-noise ratio, and selectivity

• Provides the capability for diagnosing component and system faults

• Designed for a wide range of applications from bearing analysis to leak detection

• Non-destructive; can be used while equipment is operating

• Convenient, handheld design for ease of use

• User-friendly controls include potentiometer for on/off power and sensitivity adjustment; output switch; and gain mode switch

• Dual-output analog meter for ultrasonic signal and battery level indication

• No calibration or special maintenance required

• Operated on a single 9V a1kaline battery

• Extruded almninum case maximizes tool life in harsh shop environment

• Includes several attachments for testing in contact and scan mode

• Selectable length probes increase the reach for testing

• Includes industrial grade headset available in over-the­head or behind-the-head model for use with hardhat

• Compatible with SoundCTRL System for signal logging, benchmarking, and trending

BETWEEN_SOUND AND ULTRASOUND

Rate of Atienuaiion- high frequency ultrasound attenuates faster than audible sound. Ulifasound cannot be detected very for from the source.

Shielding - ultrasound is easily shielded because it travels in short tight wavelengths

Directivity - ultrasound tends to travel away from its source in the shape of a cone, ultrasound disperses less and therefore tends not to travel around corners

THINGS TO REMEMBER

Ail mechanically operated equipment creates ultrasound

Some equipment (i.e., non-pressurized vessels) does not emit ultrasound; it may be necessary to use the Transmitter to test the equipment

As equipment failure develops, ultrasound is created before audible sound

Equipment failures can be detected earlier with ultrasound than with other diagnostic technologies such as vibration analysis or thermography

Fenomena Partial Discharge

• Arcing, tracking, dan corona adalah fenomena awal yang terjadi karena kegagalan isolasi.

• Arcing, tracking, dan corona menyebabkan proses ionisasi yang menghasilkan ozon dan nitrogen oksida.

Penyebab Korosi

• Kombinasi gas-gas tersebut dengan kandungan uap air di udara (moisture) menghasilkan asam nitrat yang sangat merusak sebagian besar material dielektrik maupun bahan komposisi metal sehingga dapat menyebabkan korosi.

~~~imana kita mendeteksi kegagalan seperti ini?
