The PV660 piezoelectric velocity sensor  is a generalpurpose vibration sensor designed for the monitoring and protection of machinery in harsh industrial environments. The PV660 is an industry standard IEPE (integrated electronics piezo electric) velocity sensor that requires a constant current power supply and provides a dynamic vibration output signal (AC voltage) on a bias level (DC voltage). It is available with a sensitivity of 4 mV/mm/s. The PV660 is available as a sensor only (with a top connector). This allows a range of cable assemblies to be used to connect the sensor to the monitoring system, depending on the application/environment. The PV660 is available in standard versions for use in standard (non-hazardous) areas only.
