Product Artikel: Meggitt Vibro-Meter PV685 Piezoelectric Accelerometer
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 vibration sensor (vibration transmitter) Quasi-static output signal (4 to 20 mA proportional to 0 to 10, 20, 25, 50 or 100 mm/s) indicating InchoverallInch vibration Typically connected to a machinery monitoring system for protection applications and/or a control system such as a DCS or PLC for monitoring and/or control applications IP67 protection rating
