Product Details

RS94N intelligent condition monitoring and protection device can realize the measurement function of different monitoring conditions by changing parameters through transmitter configuration, and can monitor and protect vibration acceleration, vibration velocity (rms,pk), shell vibration (absolute vibration), shaft vibration, shaft displacement, low frequency vibration velocity, thermal expansion, eccentricity, rotational speed and other conditions. The condition monitoring and protection device meets the requirements of low frequency (0.2-30Hz) and medium frequency (2.5Hz-5kHz) for users to choose. When the external key-phase eddy current sensor is connected, it can display the real-time waveform, pass-frequency vibration amplitude, rotating speed and 1X phase of each channel for fault diagnosis and analysis.
