VB-Z720 Dual channel Pendulum Monitoring InstrumentDetailed product description：

The VB-Z720 dual channel runout monitoring device has two independent channels that work independently and display independently. Each channel inputs signals from two eddy current sensors, which can monitor the shaft runout online for a long time. It is suitable for various types of hydro machinery.

Fault monitoring monitors the runout or radial vibration of low-frequency mechanical (such as water turbines) rotors, and monitors the increase in runout and vibration caused by rotor imbalance, misalignment, and loose components.

Measure the pitch or radial vibration (amplitude) of the parametric rotor. Various types of water turbines, etc.
