YD220 Integrated Axial Oscillation Transmitter
YD220 Integrated shaft vibration transmitter is used with eddy current sensor, can be widely used for the measurement and protection for electric power, metallurgy, petrochemical, steel, paper industries and some other large rotating machinery shaft vibration (vibration of the rotor relative to the bearing cover). Mainly monitor the radial vibration of rotor in rotating machines, monitor because of rotor unbalance, misalignment, parts loosening or other reasons that cause vibration increases.
Main Technical Parameters
