Parker Meggitt

Parker Meggitt (formerly Meggitt Sensing Systems) is a leading manufacturer of condition monitoring instruments, vibration sensors, proximity transducers and dynamic measurement systems for turbomachinery, compressors, gas turbines and rotating industrial machines. As part of Parker Hannifin Corporation, Parker Meggitt supplies accelerometers, eddy current proximity systems, strain gauge amplifiers and VM600 online condition monitoring systems for continuous machine monitoring in petrochemical plants, power stations and aerospace. With a catalog of 971 products, Parker Meggitt is the global leader in turbomachinery condition monitoring.

Parker Meggitt accelerometers (CVS100-series) are piezoresistive accelerometers for measuring mechanical vibration in the frequency range of 2 Hz to 20 kHz on bearing housings, compressor casings and turbine frames. The CVS100 version with A01-B02-C02-D02 configuration code is a standard IEPE (Integrated Electronics Piezo Electric) sensor with built-in electronic amplifier, 4 mA constant current supply, ICP-compatible output and M6/M8 mounting connection. ATEX-certified versions are available for hazardous area monitoring in Zone 1/2.

Parker Meggitt eddy current proximity systems (EA40x-series, TQ402-series) measure absolute radial shaft vibration and axial shaft position (thrust position) of rotating shafts in turbines, compressors and large electric motors via the non-contact eddy current principle. Sensor sensitivities of 4 mV/µm and 8 mV/µm are standard; systems with 4 mV/µm give 1 volt output per 0.25 mm shaft displacement. Proximity systems are compatible with API 670 standard for turbomachinery protection systems.

Parker Meggitt VM600 rack systems are online condition monitoring systems that simultaneously process multiple vibration and axial position signals for continuous machine protection. The VM600 RPS6U rack power supply provides the VM600 rack with dual redundant power. VM600 condition monitoring systems comply with API 670 standard for turbine protection in refinery and LNG installations.

Parker Meggitt pulsation pressure sensors and dynamic pressure transducers are available for measuring pulsation in reciprocating compressor cylinders and gas pipelines. These sensors withstand pressures up to 700 bar and temperatures up to 350°C for harsh process environments. Cable assemblies and sensor brackets from Parker Meggitt are pre-assembled for direct connection to VM600 rack systems and third-party DAQ systems.

At Verkopershulp.nl you will find the complete Parker Meggitt range including accelerometers, proximity systems, VM600 rack components and connection materials. Our technical experts support you in selecting the correct condition monitoring system for your turbomachinery application, including API 670 compliance verification and integration with your existing plant DCS or safety system.

History

Meggitt Sensing Systems was part of the Meggitt PLC Group from the United Kingdom, founded in the 1940s and specializing in sensing and measurement technology for the aerospace and industrial markets. In the 1960s, Meggitt pioneered eddy current sensing technology for non-contact shaft vibration measurement in turbomachinery applications, which became essential for safe turbine operation in refineries and power stations. Meggitt grew to employ more than 7,000 people and became active in condition monitoring, aerospace and defense electronics. Parker Hannifin Corporation acquired Meggitt PLC in 2022 for £6.3 billion and integrated the Meggitt sensing systems activities into its Aerospace Systems division as Parker Meggitt. The VM600-series online condition monitoring systems and EA40x proximity sensors are market-leading products in turbomachinery monitoring worldwide.

Frequently Asked Questions

What is the difference between an IEPE accelerometer and a charge accelerometer?
An IEPE accelerometer (also ICP sensor) has a built-in electronic amplifier that converts the charge from the piezoresistive element to a low-impedance voltage signal. IEPE sensors require a constant current supply (2-20 mA) via the signal cable but are easily coupled to standard data acquisition systems. Charge accelerometers have no built-in electronics but require an external charge amplifier; they are more suitable for high-temperature applications up to 700°C.
What is API 670 and why is it relevant for Parker Meggitt products?
API 670 is the American Petroleum Institute standard for Machine Protection Systems that defines requirements for vibration, axial position and rotation speed monitoring of turbomachinery in oil refineries and gas processing plants. Parker Meggitt VM600 systems and EA40x-series proximity systems are designed and certified to comply with API 670, including requirements for accuracy, redundancy and protection signals.
Which Parker Meggitt sensor is suitable for axial shaft displacement measurement?
Parker Meggitt eddy current proximity systems (EA40x-series and TQ402-series) are specifically designed for axial shaft displacement measurement (thrust measurement) in turbines and compressors. The sensor sensitivity of 4 mV/µm or 8 mV/µm provides a linear voltage signal proportional to absolute shaft displacement. The system consists of a sensor, an extension cable and a proximity signal converter that handles signal conditioning.
What is the frequency range of Parker Meggitt vibration sensors?
Parker Meggitt IEPE accelerometers of the CVS100-series have a frequency range of 2 Hz to 20 kHz for standard mechanical vibration measurement on bearing housings and machine frames. Special high-frequency models are available up to 50 kHz for detection of cavitation and high-frequency bearing damage. Low-frequency versions (0.1-1,000 Hz) are available for structural vibration measurement and building monitoring applications.
Are Parker Meggitt sensors available for ATEX-certified zones?
Yes, Parker Meggitt supplies ATEX-certified versions of its vibration sensors and proximity systems for use in gas explosive zones (ATEX Zone 1, II 2G). ATEX versions are designed for turbomachinery monitoring in petrochemical refineries, LNG terminals and offshore platforms. IECEx certification is available for international installations. Zener barriers or galvanic isolators are required for connection to the system in the safe area.
How do I connect Parker Meggitt proximity sensors to a VM600 system?
Parker Meggitt EA40x-series proximity sensors are connected via a coaxial extension cable (standard length 5 m or customer-specific) to the VM600 proximity signal converter in the VM600 rack. The signal cable has SMA coaxial connections at both ends; the VM600 module receives the unconditioned proximity DC signal (-18 to -2V) and converts this to conditioned outputs for PLC and alarm systems.
