| Within the framework of conventional machine protection, the following parameters are predominantly monitored: | Absolute casing vibrations | VB-4xx | | Relative shaft vibrations | VB-4xx | | Absolute shaft vibration | VB-4xx | | Rolling-element bearing condition | VB-420 | | Tooth-mesh conduct (gear damage) | VB-420 | | Axial position | GP-410 | | Relative/Differential expansion | GP-410 | | Absolute/Casing expansion | GP-410 | | Valve position | GP-410 | | Eccentricity | GP-420 | | Bearing clearance | GP-420 | | Speed, zero rpm, derived values | TA-410/GP-420 | - A reference for diagnostic / analytical monitoring of machine vibrations.
- Temperature, pressure, volume and other parameters are normally integrated in the PLC control, but can also be monitored by VIBROCONTROL 4000, if the proportional signals are available in DC voltage or DC current form.
