VCM-EN SII
Overview
Dual Unit Solution; monitor TWO similar units or one VCM-E customized for a Turbine and one VCM-E customized for a Generator all in one enclosure. Each VCM-E continuously monitors and outputs 4-20mA signals for shaft grounding currents and shaft voltages.
This dual monitor is ideal for critical, large or high-speed rotating machinery requiring uninterrupted shaft grounding. With two (2) VCM's in one enclosure, the single mounting option gives you the benefit of 2 separate monitors.
Key Benefits
The ability to monitor more than one location for
Early Warning of:
- Loss of Shaft Grounding
- High Residual Magnetism
- Shaft or Rotor Rubs
- Electrical Machinery Coil and Core Problems
