Bently Nevada 330901-00-32-05-02-CN | ClickLoc Probe

Product Overview

The 330901-00-32-05-02-CN is a high-precision 3300 NSv Proximity Probe from Bently Nevada, specifically designed for applications where space constraints require a smaller sensor footprint. This 1/4-28 UNF threaded probe features a 3.2-inch case length and a 0.5-meter (20 in) total cable length equipped with a miniature coaxial ClickLoc connector. With an approximate weight ranging from 14 g to 150 g (0.5 to 5.3 oz) depending on the configuration, it provides a lightweight yet durable solution for critical vibration and position measurements. Constructed with an AISI 304 stainless steel case and a Polyphenylene sulfide (PPS) tip, this probe is built to perform in the most demanding industrial environments.

Technical Specifications

Engineering Advantages

• Lightweight Design: At a maximum weight of 150 g, this probe minimizes mechanical loading on sensitive mounting brackets while maintaining industrial-grade durability.
• Rugged Material Composition: The PPS tip and 304 stainless steel case ensure resistance to chemical exposure and physical wear in high-speed machinery.
• High-Temperature Reliability: Designed to operate up to 177°C, though users should be aware that sustained temperatures below -34°C may affect the Viton O-ring pressure seal.
• Standardized Connectivity: The 75 Ω coaxial FEP-insulated cable and ClickLoc connector provide a consistent, low-noise signal path to the proximitor.

Installation & Torque Requirements

When installing the 330901-00-32-05-02-CN, the maximum thread engagement is limited to 0.375 inches. It is essential to use the recommended torque of 5.1 N•m (45 in•lb) to ensure a secure fit; do not exceed 7.3 N•m (65 in•lb). Despite its compact 14–150 g weight, the probe is engineered to handle differential pressure via its integrated Viton O-ring, though it is not pressure-tested prior to delivery. Proper torque ensures the AISI 304 SST case maintains structural integrity during high-vibration operation.

Technical FAQs

Q1: What is the significance of the "CN" approval?
A1: The "CN" suffix indicates country-specific agency approvals, ensuring the probe meets local regulatory standards for industrial and hazardous location use.

Q2: Does the weight include the cable and connector?
A2: Yes, the 14 g to 150 g weight range accounts for the probe assembly, including the 0.5-meter cable and the ClickLoc connector.

Q3: Is this probe compatible with standard 3300 XL Proximitors?
A3: The 3300 NSv series is typically used with specific NSv Proximitor sensors to ensure correct scale factors, as it is designed for different target sizes than standard 8mm systems.
