The part number 330910-00-20-10-02-00 refers to a Bently Nevada 3300 XL NSv Proximity Probe. This eddy-current based sensor is used for the non-contact measurement of shaft vibration, axial position, and speed, primarily in compact, fluid-filmed bearing machinery.

The 3300 NSv probe is available in various probe case configurations, including armored and unarmored versions with thread sizes of 1/4-28, 3⁄8-24, M8X1, and M10X1. The reverse mount 3300 NSv probe is standard with either 3⁄8-24 or M10X1 threads. All components of the transducer system are equipped with gold-plated brass ClickLoc connectors. These connectors lock into place, preventing the connection from loosening. The patented TipLoc molding method ensures a robust bond between the probe tip and the probe body. Bently Nevada's patented CableLoc design offers 220 N (50 lb) of pull strength, securely attaching 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. These protectors help prevent most liquids from entering the ClickLoc connectors and adversely affecting the electrical signal.

Notes:

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

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

Frequently Asked Questions

Q1: What is the Bently Nevada 330910-00-20-10-02-00 Proximity Probe used for?

A: The 330910-00-20-10-02-00 is a non-contact proximity probe used for monitoring shaft vibration, shaft position, and displacement in rotating machinery.  

Q2: What is the total length of the 330910-00-20-10-02-00 probe?

A: The -10 option indicates a total system length of 1.0 meter (39 inches), providing flexibility for installation and cable routing.

Q3: What power supply is required for this 330910-00-20-10-02-00 proximity probe?

A: The 330910-00-20-10-02-00 probe requires a power supply voltage between -17.5 VDC and -26 VDC for proper operation.

Q4: What does "Supply Sensitivity Less than 2 mV change" mean?

A: This specification indicates that variations in the power supply voltage result in less than 2 mV change in the probe output, helping maintain consistent measurement performance.
