Bently Nevada 330901-00-45-10-02-00 3300 NSv Proximity Probe

Description

Fully threaded 1/4-28 UNF steel probe body (Option 00 unthreaded length) with a 4.5-inch case length (Option 45) and a 1.0-meter total length (Option 10) specifies this 3300 NSv proximity probe configuration — 330901-00-45-10-02-00.

This configuration operates as part of the 3300 XL NSv Proximity Transducer System, which is used for non-contact displacement measurements in machinery with tight installation limits. This specific unarmored variant features a standard coaxial cable equipped with a miniature coaxial ClickLoc connector (Option 02) and requires no special agency approvals (Option 00). It is designed to withstand harsh process environments, offering increased chemical resistance and superior side-view characteristics compared to older legacy transducer systems.

Features

• Thread size of 1/4-28 UNF-2A without protective stainless steel armor for direct thread mounting.
• Unthreaded length of 0.0 inches (Option 00) for fully threaded case installations.
• Overall case length of 4.5 inches (Option 45) designed for deep mechanical mounting.
• Total length of 1.0 meter (Option 10) standard cable designed to connect directly with a 3300 XL NSv extension cable and Proximitor sensor.
• ClickLoc miniature coaxial connector (Option 02) providing secure mechanical locking and preventing connection loosening.
• Polyphenylene sulfide (PPS) probe tip and AISI 304 stainless steel probe case materials for increased durability.

Applications

• Radial vibration, radial position, and axial position monitoring on fluid-filmed bearing machines.
• Heavy-duty machinery such as centrifugal air compressors, refrigeration compressors, and process gas compressors.
• Small-bore machinery and small target applications, including shafts smaller than 51 mm (2.0 in) or flat targets smaller than 15 mm (0.6 in).
• Low-clearance or tight installation constraints such as narrow counterbores or limited side-view clearances.

Technical Specifications

Installation Guidelines

• Maintain minimum case-to-case clearance and use a recommended counterbore diameter of 13 mm (0.5 in) to avoid sideview interference with surrounding metal.
• Ensure a Class 2B fit class for external-to-internal thread matching on the 1/4-28 UNF threads.
• A #3 or larger tap drill size is recommended when drilling and tapping mounting holes for this probe.
• Finger-tighten the miniature coaxial ClickLoc connector by hand, and do not exceed the maximum torque rating of 0.56 N m (5 in lb).
• Protect the probe-to-extension cable connections using connector protectors or silicone tape to prevent moisture and chemical ingress.
