Meggitt Vibro-Meter PV685 Piezoelectric Accelerometer

BRAND : Meggitt

Current output: 4 to 20 mA proportional to 0 to 10, 20, 25, 50 or 100 mm/s, ?25 to 90 °C, up to 1000 Hz.

The PV685 piezoelectric velocity sensor is a general-purpose industry standard 4 to 20 mA loop-powered vibration sensor (vibration transmitter) with a piezoelectric sensing element, integrated electronics and a current output. It is available with a sensitivity of 4 to 20 mA proportional to either 0 to 10, 20, 25, 50 or 100 mm/s, and in standard versions or Ex versions. The PV685 is designed and manufactured for use in harsh industrial environments, including hazardous areas (potentially explosive atmospheres).

Features
  • Designed for general-purpose vibration measurement, typically balance of plant (BOP) machinery such as compressors, gearboxes, motors, pumps and fans
  • Industry standard 4 to 20 mA loop-powered vibrati...
