Meggitt Vibro meter VM600Mk2 Mechanical Protection and Condition Monitoring System



Meggitt Vibro meter VM600Mk2 Mechanical Protection and Condition Monitoring System

The Meggitt Vibro meter VM600Mk2 is a second-generation mechanical protection and condition monitoring system upgraded from the first generation VM600 (launched in 2000). It retains backward compatibility (can be mixed with first generation modules, reuse racks and power supplies) and integrates protection and condition monitoring functions through the MPC4MK2 module. It supports 4 vibration channels and 2 speed/phase channels, with SIL 2 functional safety certification, IEC 62443 network safety compliance, API 670 standard compatibility and other features. It also adds 5 epoxy sealed relays and graphical configuration software (with a 50% increase in configuration efficiency) to adapt to scenarios such as gas turbine combustion dynamic monitoring and rotating machinery vibration protection. More than 8000 sets of first generation systems have been installed worldwide, and the second generation further meets the requirements. The demand for safety, integration, and ease of use in the power, oil, and gas industries.

Background and core positioning of product iteration

Key project information

Innovation points of the first generation VM600 (2000): ① Single MPC4 module covers 4 vibration channels and 2 auxiliary channels; ② Physical separation of protection and CM functions (MPC4 protection+XMV16/XC16 CM); ③ Only 4 types of basic modules, simplified spare parts; ④ API 670 Compliance

Upgrade motivation 1. Network security requirements: to address industrial cyber threats and meet the IEC 62443 standard; 2. Function integration: Solve the problems of asynchronous first generation protection and CM data, as well as duplicate configuration; 3. Component availability: Some first generation electronic components are facing obsolescence; 4. Industry standard upgrade: API 670 version 6 update, SIL functional safety requirements popularized

The second generation core positioning retains the compatibility of the first generation while enhancing safety compliance, integration, and ease of use, adapting to the extreme environmental monitoring needs of the power, oil, and gas industries

Core modules and key parameters

1. Core module functions

Module model, core functions, key specifications

MPC4MK2 universal vibration monitoring, protection+CM integrated 4-channel dynamic signal input, 2-channel speed/phase/DC input; 5 epoxy sealed relays; Support SIL 2; Share sensor signals with XMV16

CPUMMk2 communication and rack control support protocols such as Modbus TCP/RTU, Profinet, etc; Physical key lock+password protection; IEC 62443 Compliance

RLC16Mx2 relay expands with 16 epoxy sealed relays; Support NO/NC wiring; Software configuration on/off status

XMV16 (reserved) pure state monitoring 16 channels, compatible with third-party protection system docking

XMC16 (reserved) gas turbine combustion dynamic monitoring adapted for low NOx gas turbines, monitoring combustion pulsation pressure

2. Key performance parameters

Channel capability: MPC4MK2 supports 4 vibration channels and 2 auxiliary channels per module, with a maximum of 12 modules (72 channels) per rack

Relay configuration: MPC4MK2 includes 5 relays (4 from the first generation), RLC16MM2 expansion includes 16 relays, all of which are epoxy sealed

Compliance standards: API 670 (5th edition compatible, participated in the development of 6th edition), SIL 2 functional safety, IEC 62443 network security, Class 2/Div 2 hazardous area adaptation

Software efficiency: VibroSight Protect graphical configuration software reduces configuration time by more than 50%, supports drag and drop, copy and paste

Core Upgrade and Advantages

1. Function integration upgrade

Integrated protection and status monitoring: MPC4MK2 has XMV16 CM function built-in, eliminating the need for separate CM module configuration, solving the problems of first generation data synchronization and configuration duplication

Data synchronization: Protecting complete synchronization with CM alarms and measurement data, facilitating event sequence reconstruction

Extended measurement: supports 10+measurement types such as air gap, magnetic flux, envelope demodulation, etc., and can add software customized alarms

2. Security and compliance upgrades

Functional safety: The module is designed according to SIL 2 (SIL 2 version will be released in 2022) and supports Safety Instrumented Systems (SIS) applications

Network security: dual protection of physical lock (CPUMMK2 key lock+MPC4MK2 configuration button) and password to prevent unauthorized configuration changes

Environmental protection: Relay epoxy sealing enhances adaptability to harsh environments

3. Usability upgrade

Configuration optimization: graphical interface replaces the first generation text configuration and supports batch copying of channel settings

Backward compatibility: can be mixed with first generation modules, reusing rack, power, and sensor wiring to avoid "overall replacement"

Easy maintenance: Keep XMV16/XMC16 modules, existing CM functions do not need to be upgraded

Applicable scenarios and industry adaptation

Application scenario adaptation device core value
