VIBRO-METER 200-510-111-035 Mechanical protection card

Product overview

Vibro-Meter® VM600 MPC4 mechanical protection card is the core component of Meggitt's VM600 series mechanical protection system (MPS), which belongs to Vibro-meter product line. The card is designed for real-time protection and basic condition monitoring of industrial machinery, and it is highly programmable and multifunctional.

Key features and advantages

1. Multi-channel processing capacity

4 dynamic signal channels: 4 dynamic signal inputs can be measured and monitored simultaneously.

2 tachometer (speed) channels: support 2 speed input monitoring.

Fully programmable input: accepts various signal types such as acceleration, velocity and displacement (proximity).

2. Advanced signal processing

Adopt the most advanced DSP technology for real-time measurement and monitoring.

Programmable filter supporting broadband and narrowband

In order tracking mode, amplitude and phase are monitored simultaneously.

Digital processing functions include:

digital filtering

Integral or differential (as required)

Rectification (RMS, average, true peak value or true peak value)

Order tracking (amplitude and phase)

Sensor-target gap measurement

3. Alarm and safety functions

Programmable Alert, Danger and OK setpoints

Adaptive Alert and Danger levels

Built-in "OK system" continuously monitors the signal level of measuring chain.

The LED indicator on the front panel shows the status and alarm.

4. Hardware design features

The front panel BNC connector facilitates the analysis of buffered "raw" sensor signals.

Power supply integrating sensor and signal conditioner

Support hot plug (online card insertion and removal)

Available in "standard", "separated circuit" and "safe" (SIL) versions.
