In modern industry, the operating environments for aerospace, power generation, and petrochemical equipment are extremely harsh. How do we ensure these multi-million dollar rotating machines (such as gas and steam turbines) run safely and efficiently? Parker Meggitt and its Vibro-Meter® brand provide world-leading solutions.

1. Why Global Industrial Giants Choose Meggitt?

Meggitt is a global engineering group specializing in smart sub-systems for extreme environments. Its Vibro-Meter brand has over 70 years of heritage and is renowned for:

• Unmatched Reliability: Preventing catastrophic failures in mission-critical assets.
• Operational Excellence: Reducing unplanned downtime and maintenance costs.
• Environmental Compliance: Helping reduce fuel consumption and emissions (CO2,NOX) through precision monitoring.

2. The "Brain": VM600 Online Monitoring Platform

The VM600 series is the flagship online monitoring system, certified by TÜV Nord for SIL 1 safety requirements, complying with international standards like IEC 61508.

Hardware Architecture: Modular Design

The VM600 uses a rack-based design with specific cards for different functions:

1. MPC4 & IOC4T (Protection): Real-time monitoring and machinery protection for vibration, speed, and displacement.
2. AMC8 & IOC8T (Condition Monitoring): Advanced data acquisition for in-depth machinery health analysis.
3. XMC16 & XMV16 (Performance & Dynamics): Specialized in combustion dynamics and turbine performance.

3. The "Senses": High-Precision Sensor Series

Meggitt provides a comprehensive range of sensors capable of operating from cryogenic temperatures (-196°C) up to extreme heat (700°C).

4. The Measurement Chain Logic

A critical feature of Meggitt’s technology is the Measurement Chain. Since sensors often operate in 700°C heat where electronics would fail, the system is split:

1. Sensor: The "front-end" in the hot zone (e.g., CA202).
2. Cable: High-temperature mineral-insulated (MI) cables.
3. Signal Conditioner: The IPC707 or IPC704 converts raw charge signals into standard current/voltage for the VM600 rack.

• Vibro-Meter®: The gold standard for turbomachinery monitoring.
• Wilcoxon Research®: High-reliability industrial vibration sensors (e.g., the 786A series).
• Endevco®: Leading brand for flight testing and automotive crash testing.
• Sensorex®: Specialists in LVDT displacement and inertial sensors.
