Meggitt offers HART-enabled vibration sensors
Meggitt's PCH420V vibration sensor has a programmable transmitter that allows vibration data to be accessed by HART enabled process controllers.
Meggitt's PCH420V is the first HART®-enabled piezo-electric vibration sensor 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 are capable of 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 only offering snapshots of asset performance and employing batteries that require frequent replacement. Utilizing PCH…
