With outstanding battery lifetime and powerful multichannel analog-front-end subsystem, RL-R19 is ready to help you with different kinds of complicated measurements. Our software and hardware team has worked to develop a convenient tool, which enables you to: examine the health of your equipment in real time using a powerful vibration diagnostic tool; balance rotating parts of different equipment; • analyze analog signals in real time with FFT-based...

Data Acquisition System and Spectrum Analyzer RL-R19 Key features Operation Modes RL-R19 device can operate in one of the two modes: DAQ system and Signal Analyzer. In the DAQ system mode the device enables you to: • collect signals; • transfer data to PC for subsequent or online processing. The Signal Analyzer mode allows the user to: • make measurements, register and analyze data; • perform various types of spectral analysis; • perform diagnostics of possible equipment defects (in bearings, gearings, etc.); • perform dynamic balancing of rotors and rotating parts. Sensors RL-R19 works...
