The Bently Nevada 330525-02 (Velomitor XA) is a high-performance piezoelectric velocity sensor specifically designed to monitor the casing vibration of industrial rotating machinery. Unlike traditional moving-coil velocity transducers, the Velomitor XA contains no moving parts. Instead, it captures acceleration signals via piezoelectric ceramic elements and utilizes onboard electronics to integrate them into a velocity signal. This solid-state design eliminates performance degradation caused by mechanical wear, significantly enhancing the sensor's reliability and operational lifespan.

The Velomitor XA (eXtended Application) Sensor is aruggedized version of Bently Nevada's 330500 VelomitorSensor. Its 316L stainless steel case and unique, weatherproofconnector and cable assembly permit mounting without ahousing. The Velomitor XA Sensor cable assembly is suitablefor use in moist environments, and the Velomitor XA Sensordesign meets the requirements of IP-65 and NEMA 4X dustratings when properly installed with a mating extensioncable.

The 330525-02 Bently Nevada Velomitor XA Piezo-velocitySensor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 330525-02 Velomitor XA Piezo-velocity Sensor Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
As an "XA" (Extended Application) version, the 330525-02 is optimized for more rigorous industrial environments. It features a fully welded 316L stainless steel housing with excellent sealing capabilities, allowing it to withstand humidity, chemical corrosion, and extreme temperature fluctuations. Typically mounted on bearing housings or machine casings, this sensor is used to detect faults such as imbalance, misalignment, and bearing damage, serving as a critical component of the Bently Nevada 3500 Machinery Protection System. Its two-wire current loop design not only reduces wiring costs but also provides strong anti-interference capabilities during long-distance signal transmission.
