Description

Sensitivity: 75 mV/mm/s (+/- 2%) Frequency range: 20 Hz – 2000 Hz Measuring direction: vertical and horizontal Min. Temp: -20 °C (under and above water) Max. Temp: +50 °C (underwater), +70 °C (above water) Hazardous area approval: no Pressure resistance: max. 5 bar Depth: max. 50 m Connection cable type: Integrated The velocity sensors ofBrüel & Kjær Vibro measuremechanical vibrations in the frequency range 1 Hz to 2,000 Hz.Their high level of reliability hasbeen proven by long-term installations in industry. Velocity sensors are used for themeasurement of the • absolute casing vibrations • absolute bearing vibrationsin machines. Coordinated solutions The resonant frequencies of thevelocity sensors are at 8 Hz or15 Hz depending upon their different constructional features.Through electronic linearization ofthe respective frequency range itis possible to also measure vibrations that lie well below theseresonant frequencies with highaccuracy. The measuring andmonitoring instruments ofBrüel & Kjær Vibro operate withlinearization circuits which areexactly tuned to the characteristics of our velocity sensors
