Velocity sensors

The new, lower-cost 786V velocity sensor captures the frequency range of most common machine faults, in a lighter-weight, more compact housing than legacy velocity sensors.

786V velocity sensor

Model: 786V

With a wide frequency response range (1-12,000 Hz at +/- 3dB), the 786V can capture signs of the most common developing faults - imbalance, misalignment, looseness - on rotating machines. A 100 mV/in/sec sensitivity and +/-5% sensitivity tolerance make for excellent measurement accuracy, and the sensor's rugged design ensures long-term reliability in industrial installations.

Key features and benefits

  • Velocity vibration measurements can be easily compared against ISO standards
  • Ideal for monitoring common mid-frequency faults – imbalance, misalignment, looseness
  • Eliminates noise influences from external integrators
  • More compact size than legacy sensors
  • Lower cost without loss of reliability or performance

The new 786V provides a broader frequency response, tighter sensitivity tolerance, higher vibration limit, and a more compact size than the legacy 793V sensor, at a significantly lower cost.
