The 330908-00-20-10-02-00 is a 3300 NSv reverse mount probe with a 3/8-24 thread, a 2.0-inch case, and a 1.0-meter cable that is compatible with 3300 RAM systems, featuring enhanced chemical resistance and superior side-view characteristics. It utilizes patented TipLoc and CableLoc technologies for robust construction, with gold-plated ClickLoc connectors.

The 3300 XL NSv Transducer System design allows it to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. Upgrades from the 3300 RAM system to the 3300 XL NSv system may use the existing probe, extension cable, and monitoring system with 3300 XL NSv Proximitor Sensor. Upgrades from the 3000-series or 7000-series Transducer System must replace the probe, extension cable, and Proximitor Sensor with NSv components. 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.

Refining & Petrochemical Industry
Used in enclosed, confined hydrocracking and high-pressure recycle gas compressors to measure high-speed shaft vibration within narrow bushings and blind housing holes.
Hydroelectric Power Industry
Mounted via external housings inside enclosed guide bearings of small bulb or Pelton hydro-turbine generator units to monitor oil film clearance and shaft runout in restricted spaces.
Pulp & Paper Industry
Used in compact bearing boxes of high-speed paper machine press and dryer sections, accurately monitoring roller shaft vibration close to metal walls in high-temperature, moisture-rich environments.
Wind Power Industry
Deployed inside highly compact wind turbine step-up gearboxes, positioned between miniature gaps of planetary gears and high-speed output shafts to precisely detect mechanical alignment and dynamic vibration.
Mining & Heavy Crushing Machinery
Installed within central drive shaft seals and compact bearing chambers of heavy-duty vertical mills and cone crushers to deliver long-term static and dynamic displacement tracking within a tiny radius.
Coal Chemical & Fertilizer Industry
Operates inside compact shaft seal cavities of high-pressure methylamine pumps and CO2 compressors in ammonia and urea plants, overcoming high pressure and chemical attack to provide real-time displacement monitoring.
When operating the 330908-00-20-10-02-00 reverse mount probe, the initial physical gap must be precisely adjusted via the external housing to achieve a DC voltage of -10 VDC using a Proximitor to ensure operation at the exact center of its linear range. Tighten strictly within the torque limit of max 22.6 N·m while protecting the tip from impact, and ensure that the side clearance between the probe and surrounding metal objects complies with reverse-mount specifications to prevent signal distortion despite its superior narrow side-view characteristics. Lastly, this 1.0-meter integral cable probe must strictly pair with a 4.0-meter 3300 NSv dedicated extension cable and Proximitor sensor, and mixing components with 3300 XL or other standard series is strictly forbidden.
The 330908-00-20-10-02-00 probe features a temperature-compensated eddy-current coil and a shielded 1.0-meter coaxial cable to prevent thermal drift and electromagnetic interference inside compressors.
It is a reverse mount probe within the Bently Nevada 3300 NSv eddy current transducer system, utilized to measure relative displacement on metallic surfaces.
What thread specification does 330908-00-20-10-02-00 have?
This specific model is configured with a standard 3⁄8-24 UNF thread.
What connector is used on the 330908-00-20-10-02-00 hardware?
It is equipped with a gold-plated brass ClickLoc coaxial connector.
What is the physical feature of the ClickLoc connector on 330908-00-20-10-02-00?
The ClickLoc connector features a physical locking mechanism that locks into place to prevent the connection from loosening.
What probe tip bonding method is applied to 330908-00-20-10-02-00?
It applies the proprietary TipLoc molding method, establishing a robust bond between the probe tip and the probe body.
