The Bently Nevada 330908-00-40-50-02-CN is a 3300 XL NSv Proximity Probe used for high-precision, non-contact vibration and position monitoring in industrial machinery. It features a 4.0-inch case (unthreaded), 0.5-meter cable, standard connector, and China agency approval, suitable for environments with restricted mounting space.

The 3300 NSv probe comes in varying probe case configurations, including armored and unarmored 1/4-28, 3⁄8-24, M8X1, and M10X1 probe threads. The reverse mount 3300 NSv probe comes standard with either 3⁄8-24 or M10X1 threads. All components of the transducer system have gold-plated brass ClickLoc connectors. ClickLoc connectors lock into place and prevent the connection from loosening. The patented TipLoc molding method provides a robust bond between the probe tip and the probe body. Bently Nevada’s patented CableLoc design provides 220 N (50 lb) of pull strength and securely attaches the probe cable to the probe tip.

Connector protectors are recommended for use on the probe-to-extension cable connection, as well as on the cable-to-Proximitor Sensor connection. Connector protectors prevent most liquids from entering into the ClickLoc connectors and adversely affecting the electrical signal(2).

Notes:

(1) Proximitor Sensors are supplied by default from the factory calibrated to AISI 4140 steel. Calibration to other target materials is available upon request.

(2) Silicone tape is also provided with each 3300 NSv extension cable and can be used instead of connector protectors. Silicone tape is not recommended in applications where the probe-to-extension cable connection will be exposed to turbine oil.

Product Applications

Oil and gas: Monitor the shaft vibration and axial displacement of centrifugal compressors, steam turbines and pump units to prevent shutdowns due to mechanical failures.

Electric power industry: Bearing monitoring for hydro turbines or small steam turbines to ensure the stability of power generation equipment

Chemical plant: For displacement monitoring of high-speed auxiliary equipment, especially in situations where installation space is limited (the NSv series is specifically designed for narrow spaces).

General manufacturing industry: Any factory environment where precise monitoring of the mechanical health status of rotating shafts is required.
