MPC4 card
The MPC4 machinery protection card is the central element in the VM600 series machinery protection system (MPS), from Meggitt’s Vibro-Meter® product line. This very versatile card is capable of measuring and monitoring up to four dynamic signal inputs and up to two speed inputs simultaneously.
The dynamic signal inputs are fully programmable and can accept signals representing acceleration, velocity and displacement (proximity), among others. On-board multichannel processing allows measurement of various physical parameters, including relative and absolute vibration, Smax, eccentricity, thrust position, absolute and differential housing expansion, displacement and dynamic pressure. Digital processing includes digital filtering,integration or differentiation (if required), rectification (RMS, mean value, true peak or truepeak-to-peak), order tracking (amplitude and phase) and measurement of the sensor-target gap.
