ClickLoc Probe Bently Nevada 330901-00-20-05-01-00

Product Overview

The Bently Nevada 330901-00-20-05-01-00 is a high-precision 3300 NSv (Narrow Space viton) proximity probe specifically engineered for space-constrained industrial environments. This "Narrow Space" transducer is ideal for centrifugal compressors, pumps, and small-diameter shafts where a standard probe’s side-view would cause interference. Featuring a 1/4-28 UNF thread and a compact 2.0-inch case, this U.S.A.-made sensor provides reliable non-contacting displacement data in temperatures ranging from cryogenic levels to extreme heat.

Technical Configuration

This 330901 configuration is optimized for miniature mounting footprints without compromising durability:

• Full Model: 330901-00-20-05-01-00
• Thread Specification: 1/4-28 UNF (0.375 in maximum engagement).
• Unthreaded Length (00): 0.0 in (fully threaded for versatile depth adjustment).
• Overall Case Length (20): 2.0 in (50.8 mm) stainless steel body.
• Total Length (05): 0.5 meter (20 in) integrated lead.
• Connector Type (01): Miniature coaxial ClickLoc connector with integrated protector.
• Agency Approval (00): Not required (Standard configuration).

Technical Specifications

Installation & Maintenance

When installing the 330901-00-20-05-01-00, adhere to the recommended torque of 5.1 N•m (45 in•lb) to ensure a secure fit without damaging the 1/4-28 threads. The 3300 NSv probes are designed to seal differential pressure via a Viton O-ring between the probe tip and case. Note that sustained exposure to temperatures below -34°C (-30°F) may impact the longevity of the pressure seal. Always ensure the miniature ClickLoc connector is properly seated within its protector to maintain signal integrity in oily environments.

Engineering Advantages

The 3300 NSv series provides a distinct advantage in restricted envelope applications where standard 8mm probes cannot fit. The use of high-grade 304 Stainless Steel and a PPS tip ensures resistance to corrosive industrial fluids and mechanical wear. This probe is specifically designed to eliminate "crosstalk" from adjacent metal surfaces, making it the premier choice for narrow-space bearing housings and high-speed motor monitoring where precision is non-negotiable.

Technical FAQs

Q1: What is the maximum thread engagement for this model?
A1: The maximum thread engagement for the 1/4-28 UNF case is 0.375 inches.

Q2: Is this probe compatible with standard 3300 XL Proximitor sensors?
A2: No. This probe must be paired with a 3300 NSv Proximitor to ensure correct calibration and output for narrow-space measurements.

Q3: How does the "No Armor" option affect usage?
A3: The unarmored (00) version is more flexible and lighter (minimum 14g), making it ideal for routing through internal machine conduits where physical abrasion is not an immediate concern.
