Velocity Sensor Works With Condition And Health Monitoring Systems

Meggitt has boosted its Vibro-Meter product line with a velocity sensor that works with all condition and health monitoring systems, including Meggitt’s VibroSight. The new PV 102 is a 100 mV/inch/second (3.94 mV/mm/s) piezoelectric velocity sensor for vibration monitoring of turbomachinery and other rotating equipment.

The uncertified version of the PV 102 has CE approval. The certified version of the PV 102 carries ATEX, IEC and CSA hazardous area certifications, which are commonly required in the nuclear and fossil power generation, oil and gas and petrochemical industries. Brazilian INMETRO approval is expected later in 2011.

The PV 102 is suitable for condition monitoring of motors, pumps, fans, compressors and turbines, including steam and gas (aeroderivative and frame) turbomachinery. The PV 102 may be used to complement proximity probes in a condition monitoring or protection system. The standard output of the PV 102 is fully compatible with systems currently employed in industrial environments, such as Meggitt’s VM 600 hardware with VibroSight Total Condition Monitoring software from the Vibro-Meter product line.

Where piezoelectric velocity sensors are installed, the PV 102 is a drop-in replacement including form, fit, function, wiring and performance. The PV 102 has a lower noise floor to help resolve low vibration signals. The sensor is also tuned for band-pass flatness for improved repeatability. The PV 102 utilizes  316L stainless steel with true hermetic sealing verified by helium leak testing.  

The PV 102 is shipped with both 1/4-28 to 1/4-28 and1/4-28 to M8 mounting studs to meet the needs of U.S. and international customers. Other mounting options are available from Meggitt, such as a 1/4-28 to M6 stud, cement mounting pads and isolator mounting pads, which electrically isolate the sensor from the machine it is monitoring to protect against high voltage spikes.  Meggitt also provides several standard cable assemblies with MIL-C-5015 style sensor connectors and Teflon-shielded, twisted pair cable.
