Vibro-meter VM600 MPC4 Product Overview

Vibro-meter VM600 MPC4 is the core component of the VM600 series mechanical protection system(MPS)produced by Vibro-Meter(now Meggitt).It uses advanced digital signal processing technology(DSP)to monitor the vibration of the machine in real time to ensure the normal operation of the machine.The protection card can simultaneously measure and monitor up to four dynamic signal inputs and two speed inputs,such as acceleration,speed and displacement(approach)signals,and is suitable for monitoring vibration,bearing conditions,mechanical operating conditions,etc.of various rotating machinery.

Main features and advantages

Multi-channel monitoring

VM600 MPC4 has 4 dynamic signal channels and 2 speed(speed)channels,which can be programmed separately,support multi-channel data acquisition,and can monitor multiple points at the same time to improve monitoring coverage.

Advanced digital signal processing technology

Adopt the latest DSP technology to achieve real-time measurement and monitoring,provide high-resolution measurement and real-time response,and ensure the safety of key equipment.

Programmability and flexibility

Programmable wideband and narrowband filters,monitoring both amplitude and phase.

Programmable alarm,danger and deterministic set points,adaptive alarm and danger levels.

Supports a wide range of signal processing functions such as digital filtering,integration or differentiation,rectification(RMS,average,true peak or true peak-to-peak),order tracking(amplitude and phase)and measurement of sensor-to-target gap.

Integrated power supply and interface

Integrated power supply for sensors and signal conditioners such as IEPE accelerometers and proximity measurement systems.

Front panel BNC connector for easy analysis of buffered“raw”sensor signals.

Available in“standard”,“isolated circuit”and“safety”(SIL)versions to meet different application requirements.

High reliability and stability

The MPC4 performs self-test and diagnostic routines at power-up.

The built-in“OK system”continuously monitors the signal levels provided by the measurement chain(sensor and/or signal conditioner)and displays any problems caused by broken transmission lines,sensor or signal conditioner failures.

Communication and integration

Supports communication with host computers and DCS/PLC systems for centralized management and analysis.

The design of VM600 rack,mechanical protection card,condition monitoring card and related software complies with the isolation requirements of mechanical protection system(MPS)and condition monitoring system(CMS)of API670 standard,ensuring that the function of MPS does not depend on the operation of CMS and will not be affected by the operation of CMS.

Application fields

VM600 MPC4 is widely used in the field of vibration monitoring and fault diagnosis of rotating machinery in the power,petroleum,chemical,steel,cement and other industries.It is suitable for real-time monitoring and protection of the operating status of industrial equipment,such as vibration monitoring and protection of turbines and generators,real-time monitoring and fault diagnosis of compressors,pumps and drilling equipment,and status monitoring of high-speed centrifuges and mixing equipment.
