Bently Nevada 330102-00-12-10-02-05 3300 XL 8mm Proximity Probe

Product Overview

The Bently Nevada 330102-00-12-10-02-05 represents the gold standard in non-contact displacement sensing. As a primary component of the 3300 XL 8mm Proximity Transducer System, this probe provides critical data for radial vibration, axial thrust, and speed measurements. This specific model features factory-installed stainless steel armor, offering superior mechanical protection in high-debris environments. We supply this product as 100% Brand New, manufactured in the U.S.A., and shipped in original factory packaging.

Part Number Breakdown

Bently Nevada utilizes a modular coding system to define the physical dimensions and certifications of the 330102 series:

Technical Specifications

• Signal Output: Compatible with 3300 XL Proximitor® 200 mV/mil (7.87 V/mm) scale factor

Engineering Advantages

The 330102-00-12-10-02-05 addresses several high-stakes industrial engineering challenges:

• Extreme Mechanical Durability: The integrated armor prevents cable crushing and abrasion in harsh environments. This design eliminates the need for external conduits in tight spaces, protecting the signal path from high-velocity oil spray or maintenance-related physical impact.

• Thermal Resilience: The PPS tip and stainless steel case withstand massive thermal cycles from -51 °C to +177 °C. This stability prevents "gap drift," ensuring the control system receives accurate data during machine startup and full-load operation.

• Chemical Resistance: The AISI 303/304 stainless steel body resists corrosion from synthetic lubricants and caustic industrial fluids, maintaining the structural integrity of the probe thread and mounting point.

• EMI/RFI Shielding: The ClickLoc™ connector system and armored cable provide a low-impedance path to ground, effectively shielding the sensor from electromagnetic interference caused by nearby high-voltage motors or VFDs.

FAQs

• Does the armor affect the electrical length of the probe?

  No. Bently Nevada calibrates the internal coaxial cable length independently of the armor. The 1.0-metre total length remains electrically consistent with standard 3300 XL 1-meter Proximitor® systems.

• Can I swap a non-armored probe with this armored version?

  Yes. As long as the base model (330101 vs 330102) shares the same unthreaded and case length requirements, you can upgrade to the armored 330102 version without recalibrating the Proximitor.

• What is the correct way to clean the probe tip?

  Use a clean, lint-free cloth and a solvent like isopropyl alcohol. Do not use metal scrapers, as any damage to the PPS tip or the underlying coil will degrade the linearity of the 4-20mA or voltage output.

• How does the ClickLoc™ connector improve reliability?

  The ClickLoc™ design features a gold-plated center pin and a "locking" mechanical feel. It resists loosening due to machinery vibration, which is a frequent cause of "intermittent signal" alarms in older-style connectors.
