Bently Nevada 330901-00-19-10-02-00 3300 NSv Probe Proksimitinya

Description

Option 00 (0.0 in unthreaded length) and Option 19 (1.9 in overall case length) specify this unarmored standard-mount probe configuration — 330901-00-19-10-02-00. This 3300 NSv Proximity Probe features a 1/4-28 UNF thread without stainless steel armor, facilitating installation in locations with limited radial clearance or restricted target size. The system interfaces with the 3300 XL NSv Proximitor Sensor and extension cable to measure non-contact shaft vibration and axial position on small-diameter rotors or high-speed machinery.

In contrast to variants featuring protective stainless steel armor or integrated connector protectors, this specific model (Option 02) includes a miniature coaxial ClickLoc connector with a standard FEP-insulated coaxial cable. With an overall total length of 1.0 meter (Option 10) and no hazardous area agency approvals required (Option 00), this component provides a direct replacement for standard unarmored configurations in general-purpose industrial environments.

Features

• Option 00 unthreaded design provides a fully threaded 1/4-28 UNF-2A probe body.
• Option 19 case length sets an overall thread casing of 1.9 inches.
• Option 10 total length specifies a 1.0 meter (39 in) probe cable assembly.
• Option 02 connector includes a miniature coaxial ClickLoc connection with standard FEP-insulated cable and no connector protector.
• Option 00 approval status is designated for standard, non-hazardous area applications.
• Polyphenylene sulfide (PPS) tip material resists chemical degradation in process environments.
• AISI 304 stainless steel case material provides structural rigidity in demanding industrial installations.

Applications

This proximity probe is used in rotating machinery protection and monitoring systems where physical access or target geometries are constrained. Typical applications include:

• Small-bore machinery and small-diameter rotating shafts.
• Aeroderivative gas turbines and high-speed turbocompressors.
• Fluid-film bearing radial vibration and axial thrust measurements in pumps.
• Industrial gearboxes and high-speed spindles with limited radial target clearance.

Installation Guidelines

Correct installation is necessary to prevent premature mechanical or electrical degradation of the proximity probe. Observe the following standard installation practices:

• Use a #3 or larger tap drill when drilling and tapping a mounting hole for this 1/4-28 probe.
• Ensure the unthreaded length (0.0 in) matches the physical housing recess depth so the threads engage properly without binding.
• Do not exceed the maximum case torque limit of 7.3 N m (65 in lb) during standard installation; recommended torque is 5.1 N m (45 in lb).
• Maintain a minimum bend radius of 25.4 mm (1.0 in) on the coaxial cable to prevent internal conductor damage.
• To shield against electromagnetic fields and avoid cross-talk on small shafts, maintain a minimum separation of transducer tips of at least 25 mm (1.0 in) for axial position or 23 mm (0.9 in) for radial vibration measurements.
• Protect the coaxial connector connection using connector protectors or silicone tape to prevent fluid ingress. Avoid silicone tape in direct turbine oil exposure environments.

Compliance and Certifications

This standard unarmored configuration (Option 00) is supplied without specific hazardous area approvals. It is intended for use in general-purpose industrial environments where explosive gas or dust atmospheres are not present.
