Meggitt's PCH420 series are the first HART-enabled piezo-electric vibration sensors enabling continuous online monitoring of balance-of-plant assets with a digital connection to PLC or DCS systems for local analysis of multiple vibration bands. They support installation in multi-drop configurations and reduce wiring requirements. HART functionality enables the user to specify vibration frequency bands, detector types and full-scale measurement ranges—effectively enabling field-configuration for specific monitoring requirements.
PCH420 sensors 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. PCH systems are less than half the cost of wireless monitoring systems that require gateways and other infrastructure to install, and can cost more than $1,000 per measurement point. The easily implemented technology allows data to be accessed by HART-enabled process controllers and information systems for better-informed decisions and improved predictive diagnostic capabilities.
Meggitt's new technology adds vibration sensors to the ranks of temperature, pressure, flow, level and analytical transmitters, which have been HART-capable for more than a decade.
