Vibro-meter VM600 MPC4 200-510-100-034
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 true peak-to-peak), order tracking (amplitude and phase) and measurement of the sensor-target gap.

The MPC4 performs a self-test and diagnostic routine on power-up. In addition, the card’s builtin “OK system” continuously monitors the level of signals provided by a measurement chain (sensor and/or signal conditioner) and indicates any problem due to a broken transmission line, faulty sensor or signal conditioner.
