Product Overview

The 330101-00-17-10-02-00 (330101-00-17-10-02-00) is a high-precision 3300 XL series 8 mm proximity probe engineered by Bently Nevada for critical machinery protection. This eddy-current sensor is a foundational component for Turbine Supervisory Instrumentation (TSI) systems, facilitating non-contacting displacement measurements of vibration and axial position. Designed for deployment in demanding environments such as power plants, petrochemical refineries, and mining facilities, the 330101-00-17-10-02-00 delivers the high-frequency response and thermal stability required for high-speed rotating equipment. By providing accurate real-time data to Bently Nevada 3500 monitoring racks, this probe enables early fault detection, effectively preventing catastrophic failures and significantly reducing unscheduled industrial downtime.

Technical Specifications

Technical FAQs

Is the ClickLoc connector compatible with older extension cables?

The ClickLoc connector is designed to be backwards compatible with standard Bently Nevada 3300 extension cables. However, ensure the extension cable is also rated for 3300 XL performance to maintain the system's specified linearity and temperature stability.

What should I do if the probe tip is exposed to chemical fluids?

The probe tip is constructed from Polyphenylene sulfide (PPS), which offers excellent resistance to most industrial chemicals and oils. However, if the fluid is highly corrosive or contains metallic particulates, verify compatibility with the AISI 303/304 stainless steel case to prevent housing degradation.

How do I verify the probe is functioning correctly after installation?

Perform a "Gap Voltage" check using a digital multimeter at the Proximitor sensor terminals. For a 3300 XL 8 mm system, a typical gap of 1.27 mm (50 mils) should yield a DC voltage of approximately -10 VDC. If the voltage is 0 VDC or near the supply voltage (e.g., -24 VDC), check for short or open circuits in the cabling.

Engineering & Installation Guide

• Gap Voltage Setting: Precise gapping is mandatory for accurate vibration data. Always set the probe to the midpoint of its linear range (typically -10 VDC) for radial vibration. For axial thrust applications, ensure the gap is set to allow for the maximum expected float in both directions without exiting the 80-mil linear region.

• Installation Torque: Avoid over-tightening the 3/8-24 UNF threads. Use a torque wrench to ensure the probe remains secure without deforming the stainless steel case or damaging the internal sensor coils. The recommended torque is 3.5 Newton-meters (31 in-lb).

• Magnetic Interference (Side Clearance): Proximity probes generate an electromagnetic field. Maintain a minimum of 13 mm (0.5 inches) of radial clearance from any metallic surface other than the target area to prevent "side-viewing" interference, which causes measurement errors.

• Cable Management: Use the provided connector protectors to prevent the ClickLoc connection from loosening due to machine vibration. Ensure the 75 Ohm triaxial cable is routed through a conduit or secured with clips to prevent mechanical fatigue or abrasion during operation.
