Bently Nevada 330103-00-07-05-02-00 Proximity Probe | 3300 XL 8mm

Product Overview

The Bently Nevada 330103-00-07-05-02-00 serves as the primary sensor for the 3300 XL 8mm Proximity Transducer System. This eddy current probe provides high-precision, non-contact measurement of vibration and position in critical rotating machinery. We supply this unit as 100% Brand New and Original, ensuring your machinery protection system receives the highest level of signal accuracy and factory-guaranteed reliability.

Part Number Breakdown

The 330103 series utilizes a specific technical configuration to meet diverse industrial mounting requirements:

Technical Specifications

This probe delivers consistent linear output when integrated with a 3300 XL Proximitor® Sensor.

• 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

• Scale Factor: 7.87 V/mm (200 mV/mil) when properly matched

• Condition: 100% Brand New Original

Engineering Advantages

• Deep Reach Mounting: The 70mm case length facilitates installation through thick machine casings or complex bearing housings. This ensures the probe tip reaches the optimal sensing distance from the target shaft without requiring custom extension sleeves.

• Vibration-Proof Connection: The ClickLoc™ connector employs a robust mechanical locking detent. This feature prevents the cable from backing out or loosening due to continuous machine vibration, eliminating intermittent "NOT OK" signal status errors.

• Thermal Stability: Advanced engineering minimizes "thermal drift" across the full operating range. This ensures measurement accuracy remains consistent during both cold startups and high-temperature, full-load operations.

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

FAQs

Is this 0.5m probe compatible with a 5-meter or 9-meter system?

To maintain a 200 mV/mil scale factor, you must match the total electrical length. This 0.5m probe integrates into a 5-meter system when paired with a 4.5m extension cable, or a 9-meter system when paired with an 8.5m extension cable. Always check your Proximitor® label to verify the required "System Length."

How do I confirm the probe is 100% Brand New?

Every unit ships in its original Bently Nevada factory packaging with an intact serial number. The pristine condition of the gold-plated ClickLoc™ connector and the absence of thread wear confirm its 100% Brand New status.

What is the recommended installation torque?

Apply a maximum of 11.2 N·m (100 in·lb) of torque during installation. We recommend using a digital voltmeter (DVM) to monitor the DC gap voltage while gapping the probe to prevent the tip from striking the shaft.

Can I replace an older 3300 series probe with this XL model?

Yes. The 3300 XL 8mm probes maintain backwards compatibility with standard 3300 5mm and 8mm systems. However, using the full 3300 XL chain provides superior performance and immunity to electromagnetic interference.
