Meggitt Sensing Systems Has Developed The First HART Compatible Vibration Transmitter
Published by – December 7, 2015
Meggitt's field programmable vibration sensor is a 4-20 mA transmitter with HART protocol.
- Field programmable
- Standard 4-20 mA plus digital data
- Enhanced view of machinery condition
- Targeted characterization of potential faults
- Integrates with existing HART networks
- Supports multi-drop operation
Field programmability over HART networks
For over 20 years, the HART field communication protocol has grown to support over 40 million devices because of its high reliability and ease of programming. Meggitt Sensing Systems has developed the first HART compatible vibration transmitter for simplified condition monitoring of process systems. Three user configurable bands allow targeted measurements for identifying machine faults like unbalance, alignment, looseness or bearing wear conditions.
Comprehensive/full spectrum monitoring capabilities
The PCH420 series superimposes a digital signal on top of the popular 4-20 mA loop offering unparalleled flexibility for condition based maintenance of rotating equipment. Programmable bands enable further analysis of machinery spectrum to successfully identify potential faults. Simply configure the band to the frequency area containing abnormal vibration levels for a detailed view of the spectrum. Maintenance and repair can be made based on actual fault conditions.
PCH420 transmitters easily integrate with existing networks without the expense of additional infrastructure or cable networks for quick and easy visibility. They are powered by the network for continuous coverage, unlike wireless solutions which only offer snapshots of asset performance and utilize batteries that require frequent replacement. Multi-drop installations ensure up to 16 sensors can be monitored through a single port address. PCH systems are less than half the cost of wireless monitoring systems, which require gateways and other infrastructure to install, and can cost more than $1000 per measurement point.
The PCH series is designed for compatibility with HART enabled devices from a variety of suppliers. Visit the HART product catalog to view all supported devices. Using Device Description (DD) files, handheld devices or software applications can fully configure the PCH sensor in common vibration terminology.
