Meggitt Sensing Systems' PV 102 piezoelectric velocity sensor is designed for vibration monitoring of rotating equipment
Meggitt Sensing Systems' PV 102 piezoelectric velocity sensor is designed for vibration monitoring of turbomachinery and other rotating equipment. The PV 102 is a 100 mV/inch/second (3.94 mV/mm/s) piezoelectric velocity sensor. 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.
The PV 102 may be used to compliment 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.
The PV 102 has a lower noise floor to better resolve low vibration signals. The sensor is also tuned for band-pass flatness.
Sub-base isolation is designed to improve base strain sensitivity, minimize the influence of mounting on sensor data and protect against electrostatic discharge. The electronics of the PV 102 are isolated from the sensor case for higher immunity against radio frequency interference.
The PV 102 is shipped with both 1/4-28 to 1/4-28 and 1/4-28 to M8 mounting studs. Other mounting options are available from Meggitt, such as a 1/4-28 to M6 stud, cement mounting pads and isolator mounting pads that 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. Customers can choose armoured or non-armoured cable; between a foil shield with IP67 rating at the connector and a braided shield with IP68 rating at the connector; and standard or custom lengths to suit their application. Enclosures including switch and termination boxes are also available.
