Description

MPC4 Card

The MPC4 Machine Protection Card is the centerpiece of the VM600 series of Machine Protection Systems (MPS) from Meggitt’s Vibrometer® product line. The card is extremely versatile, capable of measuring and monitoring up to four dynamic signal inputs and two velocity inputs simultaneously.

The dynamic signal inputs are fully programmable and can accept the following signals

acceleration, velocity and displacement (proximity) signals. On-board multi-channel processing allows measurement of a wide range of physical parameters including relative and absolute vibration, Smax, eccentricity, thrust position, absolute and differential case expansion, displacement and dynamic pressure.

Digital processing includes digital filtering, integration or differentiation (if required), rectification (RMS, average, true peak, or true peak-to-peak), order tracking (amplitude and phase), and measurement of transducer-to-target clearance.

The speed (tachometer) input accepts signals from a variety of speed sensors, including systems based on proximity probes, magnetic pulse pickup sensors, or TTL signals. Fractional tachometer ratios are also supported.
