Bently Nevada 330902-00-30-05-02-00 3300 NSv Proximity Probe

Description

Option 00 (0.0 in unthreaded length) and Option 30 (3.0 in overall case length) specify the physical configuration of this 3300 NSv armored proximity probe — 330902-00-30-05-02-00. This non-contacting eddy-current displacement sensor features flexible stainless steel armor to shield the coaxial cable from abrasion, cutting, and mechanical damage in tight installation spaces. Configured with a 0.5-meter total length (Option 05) and a standard ClickLoc coaxial connector (Option 02), this probe provides shaft vibration and position monitoring in standard industrial environments without agency approval requirements (Option 00).

Unlike unarmored configurations such as the 330901 series, the 330902-00-30-05-02-00 probe has a robust stainless steel conduit surrounding the FEP-insulated coaxial line. This mechanical protection is suited for application environments where routing pathways expose the cabling to physical contact or abrasive surfaces. Operating within the 3300 XL NSv Proximity Transducer System, this probe pairs with the 330980 Proximitor Sensor and 330930 extension cable to perform displacement measurements on rotating shafts with small target diameters or limited clearances.

Features

• 1/4-28 UNF threaded case with a 3.0 inch overall case length (Option 30) and a fully threaded 0.0 inch unthreaded length (Option 00).
• Flexible stainless steel armor protects the 75 ohm coaxial, FEP-insulated probe cable from mechanical wear and abrasive environments.
• 0.5 meter (20 inch) total cable length (Option 05) for compact installation envelopes.
• Miniature coaxial ClickLoc connector (Option 02) features gold-plated brass construction to prevent connection loosening.
• No agency approvals required (Option 00) for standard non-hazardous industrial locations.
• TipLoc molding process provides a bond between the polyphenylene sulfide (PPS) probe tip and the AISI 304 stainless steel case.
• CableLoc design provides up to 220 N (50 lb) of pull strength between the probe cable and the sensor body.

Applications

• Radial vibration and axial position monitoring on high-speed industrial compressors and pumps.
• Small-bore machinery and aeroderivative gas turbines with limited physical installation clearance.
• Rotating machinery with target diameters smaller than 20 mm (0.8 in) where side-view interference must be minimized.
• Industrial fans, blowers, and process gearboxes requiring armored cable protection.

Installation Guidelines

• Initially thread the probe case by hand, then tighten to the recommended case torque of 5.1 N m (45 in lb). Do not exceed the maximum limit of 7.3 N m (65 in lb) to prevent thread stripping or housing distortion.
• Ensure routing paths avoid sharp bends in the armor, keeping to a minimum bend radius of 25.4 mm (1.0 in).
• Set the probe-to-target physical gap to 1.0 mm (40 mils) during machine outage using standard gauge tools to establish a baseline.
• Apply protective self-fusing silicone tape or install matching connector protectors at coaxial joints to prevent moisture or cutting fluids from compromising the high-frequency electrical signal.
• Verify that the total combined electrical length of the probe and extension cable matches the calibration requirements of the connected Proximitor Sensor.

Compliance and Certifications

• CE Mark: Compliant (when integrated within a certified 3300 XL NSv system)
• RoHS: Compliant
• Agency Approvals: Option 00 specifies that no hazardous area certifications are provided. For explosion-proof or intrinsically safe applications, select an option 05 configuration.
