Bently Nevada 330500-00-02 Velomitor Piezo-velocity Sensor

Product Introduction:
A solid-state piezoelectric velocity sensor that measures absolute (relative to free space) bearing housing, casing or structural vibration. Integral electronics convert acceleration to velocity, eliminating the need for external signal conditioning while offering wide frequency response and high reliability with no moving parts.
Technical Specifications:
  • Sensor Type: Piezo-velocity (integrated accelerometer)
  • Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5 %
  • Frequency Response: 4.5 Hz – 5 kHz (±3 dB); 6 Hz – 2.5 kHz (±0.9 dB)
  • Velocity Range: 0 – 1,270 mm/s (0 – 50 in/s) peak
  • Transverse Sensitivity: <5 %
