Description

The 330704-00-07-10-01-05 is a high-performance 3300 XL 11 mm Proximity Probe designed by Bently Nevada to provide an extended linear measurement range for critical industrial machinery. Unlike standard 8 mm sensors, this 11 mm proximity probe offers a significantly wider 4.0 mm (160 mils) linear range, making it the ideal solution for monitoring large-scale rotating assets where greater shaft movement or axial displacement is expected. As a core component of the 3300 XL series, the 330704-00-050-10-01-05 utilizes advanced eddy current technology to deliver a stable and linear voltage signal proportional to the gap between the probe tip and the target material.

Constructed for extreme durability, the 330704-00-050-10-01-05 3300 XL 11 mm Proximity Probe features an AISI 303/304 stainless steel case and a high-grade Polyphenylene sulfide (PPS) tip. This model is specifically configured with a 50 mm overall case length and a 0 mm unthreaded length, providing a compact yet robust form factor for flush-mount or sleeve-supported installations. To ensure maximum environmental protection, this proximity probe includes a Miniature coaxial ClickLoc connector with a connector protector, which shields the electrical link from moisture, oil, and dust—common contaminants in power plants and refineries.

The 330704-00-050-10-01-05 integrates Bently Nevada’s patented TipLoc and CableLoc technologies. TipLoc creates an inseparable bond between the 11 mm probe tip and the body, while CableLoc provides a high-strength cable anchor (up to 330 N) to prevent accidental pull-away failures. With a 1.0-meter (3.3 feet) total length and Multiple Approvals (CSA, ATEX, IECEx), this 3300 XL 11 mm Proximity Probe is fully compliant with the API 670 Standard, ensuring seamless interchangeability and world-class reliability in hazardous locations. Whether used for radial vibration or axial position monitoring, the 330704-00-050-10-01-05 is a cornerstone of any predictive maintenance strategy for high-value rotating equipment.

Applications

Large Steam and Gas Turbine Thrust Monitoring Due to its extended 4.0 mm (160 mils) linear range, the 330704-00-050-10-01-05 is the preferred choice for monitoring axial thrust position in large-scale turbines. It accurately tracks the longitudinal movement of the rotor relative to the thrust bearing, providing critical data to prevent rotor-to-stator contact during thermal expansion or load changes in power generation facilities.

Radial Vibration in Heavy-Duty Industrial Compressors This 11 mm proximity probe is widely applied in large centrifugal compressors used in the oil and gas industry. The robust stainless steel case and PPS tip withstand high-pressure environments and oil immersion, while the 2.2x2x119cm dimension allows for stable mounting in thick-walled bearing housings to monitor high-amplitude radial vibrations.

Hazardous Area Machinery Protection With Multiple Approvals (ATEX, IECEx, CSA), the 330704-00-050-10-01-05 is specifically designed for deployment in explosive atmospheres. It provides reliable "Keyphasor" speed detection and vibration signals for machines located in petrochemical processing zones where strict safety compliance and environmental resilience are mandatory.

Specifications

Competitive Advantage

Extended 4.0 mm Linear Range for Greater Flexibility The primary advantage of the 330704-00-050-10-01-05 is its 11 mm tip diameter, which provides double the linear range of standard 8 mm probes. This allows for more forgiving gap settings and the ability to monitor larger machines with significant thermal growth or axial play without losing signal linearity.

Integrated Connector Protection for Harsh Environments This model features a Miniature coaxial ClickLoc connector with an integrated protector. This added shield prevents the ingress of corrosive fluids and protects the connection from mechanical impact, significantly reducing the risk of signal noise or intermittent data loss in oil-laden or humid environments.

Patented TipLoc and CableLoc Mechanical Integrity The 330704-00-050-10-01-05 incorporates TipLoc molding technology, which prevents tip detachment under vacuum or high vibration. Combined with CableLoc, which ensures the 1.0-meter cable remains securely attached even under high tension (330 N), this probe offers a much longer service life than generic alternatives.

Global Multi-Agency Safety Certifications The Multiple Approvals option allows this probe to be used globally. Whether your facility operates under CSA, ATEX, or IECEx regulations, the 330704-00-050-10-01-05 meets all necessary safety benchmarks for hazardous locations, simplifying procurement and ensuring regulatory compliance.

Full API 670 Compliance and System Interchangeability As a genuine Bently Nevada 3300 XL product, this probe is fully interchangeable with other XL series proximitors and cables. It meets the strict performance requirements of the API 670 Standard, guaranteeing that the measurement accuracy and temperature stability remain consistent across the entire machinery protection system.
