330707-00-62-10-01-00 Bently Nevada 1.0m Proximity Transducer

Product Overview

The 330707-00-62-10-01-00 represents the larger-diameter 11mm variant of the 3300 XL series, offering a broader linear range compared to standard 8mm probes. It detects the precise distance between the probe tip and the target shaft without physical contact, ensuring zero mechanical wear. We supply this unit as 100% Brand New in original factory packaging, specifically calibrated to meet the rigorous demands of API 670 machinery protection standards.

Technical Specifications

Engineering Advantages

The 330707-00-62-10-01-00 utilizes Bently Nevada’s mechanical innovations to ensure data integrity in the most volatile industrial settings:

• Extended Sensing Field: The 11mm tip diameter generates a larger magnetic field than standard probes. This provides a more robust signal when monitoring large shafts or targets with less-than-ideal surface finishes.

• Superior Thermal Stability: The probe maintains high accuracy across a wide temperature gradient (up to +177°C). This allows for installation deep inside hot bearing housings where steam or friction heat is prevalent.

• ClickLoc™ Interconnect: The gold-plated ClickLoc™ connector features a positive-locking mechanism. This eliminates signal noise caused by mechanical vibration at the connection point and resists moisture ingress that typically leads to signal attenuation.

• Ruggedized Probe Case: The 6.2-inch stainless steel case protects the internal electronics from the high-pressure and corrosive environments typical of chemical processing and offshore power generation.

FAQs

Can I replace an 8mm probe with this 11mm 330707 probe?

While both utilize eddy-current technology, you cannot simply swap an 8mm probe for an 11mm probe without verification. The 11mm probe requires a different Proximitor sensor calibrated for the 11mm tip’s larger sensing field and linear range. Always check your 3500 system configuration before upgrading.

How do I set the proper gap for this probe?

Set the probe gap by monitoring the DC voltage at the Proximitor sensor output. For most 3300 XL 11mm systems, a gap that yields -10.00 VDC output represents the center of the linear range. Rotate the probe in its mount until you reach this threshold before securing the locknut.

Does this probe work with non-steel targets?

The 330707 is factory-calibrated for AISI 4140 steel. If your target is made of another material (such as stainless steel or aluminum), the sensitivity (7.87 V/mm) will change. You must recalibrate the Proximitor sensor or apply a scale factor to the data.

What extension cable is required for a 1.0m probe?

To achieve a standard 5.0m system length, pair this 1.0m probe with a 4.0m 3300 XL extension cable. For a 9.0m system, use an 8.0m extension cable. Incorrect total system length will result in significant measurement errors.
