Ultrasonic Monitor Warns of Mechanical Failure, Flow Disruption & Valve Leaks

UE Systems' Ultra-Trak 750 passively monitors structure borne ultrasounds produced by operating equipment. It can be set to detect either a rise or drop off of sound levels in real time
for trending or alarm purposes. Typical applications for Ultra-Trak include early warning of: mechanical failure, valve leakage, flow disruption, cavitation, equipment shutdown and arcing in enclosed switchgear.

Ultra-Trak may be used to monitor, trend or data log events. A unique feature is a demodulated output that allows the sensor to be connected to FFT analyzers and other recording devices. Utilizing a 4-20 mA current loop power or current loop output, it can be connected to alarms or recorders. A wide dynamic range of 120 dB and sensitivity adjustments provides users with the
capability of sensing subtle to gross changes in operating equipment. Ultra-Trak senses ultrasound centered around 40 kHz. Due to the short wave nature of these high frequencies, monitored signals are localized to the immediate area reducing the possibility of false alarms from remote sources.

Ultra-Trak is housed in a stainless steel water resistant and dust proof enclosure for operation in challenging environments. Baseline sensitivity threshold levels are set through a programmable sensitivity adjust.
