PV685 Vibration 440-685-000-111-A1-B050-C01 Piezoelectric Accelerometer

Description:

The PV685 piezoelectric velocity sensor from Meggitt’s vibro-meter® product line is a generalpurpose vibration sensor designed for the
monitoring and protection of machinery in harsh industrial environments.

The PV685 is an industry standard 4 to 20 mA loop-powered vibration sensor (vibration transmitter) that provides a vibration output signal
in a current loop. 

It is available with a sensitivity of 4 to 20 mA proportional to 0 to 20 mm/s, 0 to 25 mm/s or 0 to 50 mm/s.

The PV685 is available as a sensor only or fitted with an integral cable that is protected by a stainless-steel overbraid. Sensor only versions allow one of a range of different cable assemblies to be used to connect the sensor to the monitoring system, depending on the application and environment.
