Bently Nevada 330104-01-08-50-01-CN 3300 XL 8 mm Proximity Probe

Product Introduction

When precise vibration monitoring is critical for rotating machinery health, the Bently Nevada 330104-01-08-50-01-CN delivers reliable performance. This 3300 XL 8 mm proximity probe is designed for non-contact displacement measurement in industrial environments. Manufactured in the USA, it features an M10 x 1 thread with armor for enhanced durability. Part of the trusted 3300 XL series, this probe is built to withstand demanding conditions while providing accurate data for predictive maintenance programs.

Technical Specifications Breakdown

The 330104-01-08-50-01-CN offers a total length of 5.0 meters (16.4 feet) with an unthreaded length of 01 mm and an overall case length of 80 mm. The probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel (SST). It uses a miniature coaxial ClickLoc connector with a connector protector and standard cable. The nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 8.73 ± 0.50 Ω at 5.0 meters. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

This proximity probe is commonly used in turbomachinery, compressors, pumps, and motors where shaft vibration and position must be monitored continuously. The 5.0 meter cable length allows flexible installation in tight spaces, while the armored construction resists mechanical damage in harsh industrial settings. By integrating this probe into a condition monitoring system, operators can detect early signs of bearing wear or imbalance, reducing unplanned downtime.

Installation & Setup Guidance

Proper installation begins with verifying the probe gap at 1.27 mm (50 mils) against an AISI 4140 steel target for optimal performance. Ensure the probe is securely mounted with the M10 x 1 thread and that the cable is routed without sharp bends. The miniature coaxial ClickLoc connector simplifies field connection, and the connector protector adds strain relief. Always follow the manufacturer's guidelines for proximity probe positioning to maintain linear range and accuracy.

Maintenance & Reliability

Routine inspection of the probe tip and cable for wear or contamination helps sustain measurement accuracy. The PPS tip and stainless steel case resist corrosion and chemical exposure, extending service life. The Viton O-ring seal maintains pressure integrity, making the probe suitable for applications where differential pressure is a concern. Periodic verification of system calibration against a known target ensures consistent performance over time.

Buying Guide & Purchasing Advice

Before purchasing the 330104-01-08-50-01-CN, confirm that your system requires a 3300 XL 8 mm probe with M10 x 1 thread and a 5.0 meter cable. Verify compatibility with your existing 3300-series Proximitor sensor and extension cable. For current availability and lifecycle status, contact plcmatrix.com.
