Bently Nevada 330104-00-25-10-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330104-00-25-10-02-CN 3300 XL 8 mm Proximity Probe delivers reliable, non-contact displacement measurement. This probe is part of the proven 3300 XL series, engineered for harsh industrial environments. Its robust design includes an M10 x 1 thread and armor for enhanced durability. The 330104-00-25-10-02-CN is a key component for monitoring rotating equipment such as turbines, compressors, and pumps.

Technical Specifications Breakdown

The 330104-00-25-10-02-CN features a probe tip made of Polyphenylene sulfide (PPS) and a case constructed from AISI 303 or 304 stainless steel (SST). It has an unthreaded length of 00 mm and an overall case length of 25 mm. The total length option is 10, equating to 1.0 meter (3.3 feet). It uses a miniature coaxial ClickLoc connector with FluidLoc cable and a standard cable option. The nominal probe DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms for a 1.0 meter probe. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

This proximity probe excels in critical machinery protection systems. In steam turbine monitoring, the 330104-00-25-10-02-CN provides accurate shaft vibration and position data, helping operators avoid catastrophic failures. For centrifugal compressors, its PPS tip and stainless steel case resist oil and moisture, ensuring long-term reliability. The probe's 1.0 meter cable length suits installations where the sensor is close to the machine train, reducing signal loss.

Installation & Setup Guidance

Proper installation is crucial for accurate readings. Mount the 330104-00-25-10-02-CN using the M10 x 1 threaded hole, ensuring the probe tip is clean and free of debris. Gap the probe at 1.27 mm (50 mils) for optimal performance with an AISI 4140 steel target. Use the miniature coaxial ClickLoc connector for secure cable attachment. Verify the system uses only 3300 XL 8 mm components to maintain accuracy and interchangeability specifications.

Maintenance & Reliability

The 3300 XL 8 mm probe requires minimal routine care. Inspect the probe tip and cable periodically for physical damage or contamination. The Viton O-ring seal helps maintain pressure integrity, but verify it is not degraded in harsh chemical environments. Since the probe is passive, no electrical maintenance is needed. For consistent performance, ensure the target material remains AISI 4140 steel as calibrated.

Selection Guide & Purchasing Advice

Before ordering the 330104-00-25-10-02-CN, confirm your system requirements: the probe uses a miniature coaxial ClickLoc connector and standard cable. It is designed for use with 3300 XL 8 mm Proximitor sensors and extension cables. For replacement or new installations, verify the thread size (M10 x 1) and total length (1.0 m). plcmatrix.com offers this Bently Nevada probe with country-specific approval (CN).

Comparison with Similar Probes

Compared to standard 5 mm probes, the 3300 XL 8 mm model offers a larger sensing area and improved linear range. Unlike unarmored versions, the 330104-00-25-10-02-CN includes armor for added mechanical protection in high-vibration environments. Its PPS tip resists chemicals better than older phenolic tips, and the stainless steel case provides corrosion resistance. The ClickLoc connector simplifies installation versus screw-on types.
