Bently Nevada 330104-00-20-05-02-00 3300 XL 8 mm Proximity Probe

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330104-00-20-05-02-00 provides precise, non-contact displacement measurement. This 3300 XL 8 mm proximity probe is designed for critical rotating equipment monitoring. It features an M10 x 1 thread with armor, a 0.5 meter (1.6 feet) total length, and a miniature coaxial ClickLoc connector with standard cable. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel (SST). It seals differential pressure between tip and case using a Viton O-ring.

Technical Specifications Breakdown

The 330104-00-20-05-02-00 operates with a -17.5 Vdc to -26 Vdc power supply and draws 12 mA maximum. Its output resistance is 50 Ω, and sensitivity is less than 2 mV change per volt change in input voltage. The nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.45 ± 0.50 Ω at 0.5 meters. These specifications ensure accurate, repeatable measurements when used with a 3300 XL Proximitor Sensor and extension cable.

Industry Applications

This probe excels in steam turbines, compressors, pumps, and fans where shaft vibration and position monitoring are critical. In a typical turbine installation, the 330104-00-20-05-02-00 provides real-time data to prevent catastrophic failure. Its armored construction and sealed design make it suitable for harsh environments with moisture or debris.

Installation & Setup Guidance

Mount the probe with the M10 x 1 thread into a compatible bracket or housing. Ensure the target surface is AISI 4140 steel for optimal accuracy. Gap the probe at 1.27 mm (50 mils) during calibration. Connect the ClickLoc connector securely to the extension cable. Verify power supply voltage is within -17.5 Vdc to -26 Vdc and load is 10 kΩ for best performance.

Maintenance & Reliability

Routine inspection of the probe tip and cable for wear or damage extends service life. The PPS tip resists chemical attack, and the stainless steel case provides corrosion resistance. The Viton O-ring maintains seal integrity under pressure. Periodically verify DC resistance per the specification to detect early degradation.

Compatibility & Integration

The 330104-00-20-05-02-00 works exclusively with 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts one non-contacting 3300-series 5 mm or 8 mm probe. Use only Bently Nevada components to maintain system accuracy and interchangeability.

Buying Guide & Purchasing Advice

Before ordering, confirm your system requires an 8 mm probe with M10 x 1 thread and 0.5 meter cable. Verify the connector type matches your existing cable.
