330103-00-07-10-02-00 3300 XL 8mm Proximity Probe | Bently Nevada

Product Overview

The Bently Nevada 330103-00-07-10-02-00 functions as the primary non-contact sensor for the 3300 XL 8mm Proximity Transducer System. It measures shaft vibration, axial position, and speed on critical rotating assets such as turbines, compressors, and pumps. We supply this unit as 100% Brand New and Original, ensuring your machinery protection system maintains the high-fidelity signal integrity required for mission-critical diagnostics.

Part Number Breakdown

This model utilizes a specific configuration to accommodate deep mounting requirements:

Technical Specifications

This probe generates an eddy current field to provide a linear voltage output proportional to the gap distance.

• Tip Diameter: 8 mm

• Case Material: AISI 303 or 304 Stainless Steel (SST)

• Tip Material: Polyphenylene sulfide (PPS)

• Operating Temperature: -35 °C to +177 °C (-31 °F to +350 °F)

• Linear Range: 2.0 mm (80 mils) typical

• Standard Scale Factor: 7.87 V/mm (200 mV/mil)

• Connector Type: Gold-plated ClickLoc™ miniature coaxial

• Condition: 100% Brand New Original

Engineering Advantages

• Deep-Housing Accessibility: The 70 mm case length allows technicians to install the probe through thick machine casings or internal bearing supports. This eliminates the need for custom-machined extension sleeves to reach the target surface.

• Vibration-Proof Connection: The ClickLoc™ connector employs a robust mechanical locking detent. This prevents the cable from self-loosening under high-frequency vibration, which eliminates the "NOT OK" signal status errors common in standard threaded connectors.

• Exceptional Thermal Stability: The 3300 XL design minimizes "thermal drift" across its wide operating range. This ensures measurement accuracy remains consistent during both cold startups and full-load, high-temperature operations.

• Fluid Resistance: The PPS tip and stainless steel body resist degradation from synthetic oils, moisture, and common industrial lubricants, significantly extending the sensor's service life in aggressive turbine environments.

FAQs

Is this 1.0m probe compatible with both 5-meter and 9-meter systems?

Yes, provided you match the extension cable. For a 5-meter system, pair this 1.0m probe with a 4.0m extension cable. For a 9-meter system, use an 8.0m extension cable. Always verify that the total electrical length matches the calibration label on your Proximitor® sensor.

What is the correct way to set the probe gap?

We recommend using a digital voltmeter (DVM) to monitor the DC gap voltage during installation. For a standard 3300 XL system gapped at the midpoint, aim for approximately -10.0 VDC. This ensures the shaft remains within the sensor's linear range during operation.

Can I replace a standard 3300 8mm probe with this 3300 XL model?

Yes. The 3300 XL 8mm probes maintain full backwards compatibility with older 3300 series 5mm and 8mm systems. However, we recommend upgrading the entire transducer chain (Probe, Cable, and Proximitor) to take full advantage of the XL’s improved temperature stability.

Does this probe come in original factory packaging?

Absolutely. We supply only 100% Brand New units in original Bently Nevada factory boxes. Each unit features a unique serial number for tracking and quality assurance.
