UE Systems Ultratrak 850S

The 850s is a modern ultrasound sensor and transmitter with state-of-the-art onboard data processing designed to detect early onset failures in industrial equipment. BR> The 850s works in tandem with existing plant automation and measurement applications, providing the hardware required to detect changes in ultrasonic amplitude resulting from the degradation of equipment. The 850s can be used for a wide-range of applications, including: ultrasound condition based lubrication, bearing fault detection, valve leakage and steam trap issues with your existing measurement systems.


The 850s is ready to guard against unplanned downtime and product loss the minute it is installed. The device passively senses ultrasounds produced by mechanical equipment in the form of friction, impacting, and turbulence and processes the level of decibel into an analog signal to work seamlessly with existing PLC’s, SCADA, DCS and other automation systems. This, in turn, supports real-time data trending and alerting, making it possible to detect and address important issues earlier and faster. The 850s also employs Edge Analytics – allowing for in-device data processing, less reliance on cloud computing, and the ability to act on information in real-time. We don’t just sell products, we offer a fully comprehensive service to compliment your maintenance program. Please contact us to find out more.
