Bently Nevada 330104-00-07-90-12-05 3300 XL 8 mm Proximity Probe

Introduction

When unplanned machinery downtime threatens production targets, the Bently Nevada 330104-00-07-90-12-05 3300 XL 8 mm Proximity Probe provides the precise, reliable vibration and position data you need. This probe is part of the trusted 3300 XL series, designed for continuous monitoring of rotating equipment in demanding industrial environments.

Technical Specifications

The 330104-00-07-90-12-05 features an M10 x 1 thread with armor for robust installation. It offers an unthreaded length of 00 mm and an overall case length of 70 mm. The total length is 9.0 meters (29.5 feet), equipped with a miniature coaxial ClickLoc connector and FluidLoc cable. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel (SST). Nominal probe DC resistance is 9.87 ± 0.50 Ω at 9.0 meters. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

This proximity probe excels in monitoring critical rotating machinery such as turbines, compressors, pumps, and motors. Its high-temperature tolerance (up to +232°C for T1 classification) suits harsh environments in oil and gas, power generation, and petrochemical plants. The CSA, ATEX, and IECEx approvals ensure safe operation in hazardous areas, including Class I, Zone 0 and Zone 2 locations.

Installation Guidance

Proper installation is key to accurate readings. Mount the probe with the M10 x 1 thread into a compatible bracket or housing, ensuring the tip is gapped at 1.27 mm (50 mils) for optimal performance. Use the ClickLoc connector for secure cable attachment. For intrinsically safe installations, follow drawing 141092; for nonincendive circuits, use drawing 140979. Verify the power supply is between -17.5 Vdc and -26 Vdc for standard operation.

Maintenance and Reliability

Regularly inspect the probe tip and cable for wear or damage, especially in high-vibration or abrasive environments. The PPS tip and stainless steel case resist corrosion and mechanical stress. Check the Viton O-ring seal periodically to maintain differential pressure integrity. Following these steps extends service life and reduces unplanned downtime.

Selection and Purchasing Advice

Before ordering, confirm the probe length, connector type, and agency approvals match your application. The 330104-00-07-90-12-05 is ideal for systems requiring a 9.0-meter cable with CSA, ATEX, and IECEx certifications.
