Bently Nevada 330901-00-20-05-02-00 3300 NSv Proximity Probe

Description

330901-00-20-05-02-00: 3300 NSv proximity probe, 1/4-28 UNF thread without armor, Option 00 unthreaded length, Option 20 case length, Option 05 total length, Option 02 miniature ClickLoc connector with standard cable, Option 00 approvals not required.

This configuration features a 0.5-meter standard cable and does not include a connector protector (Option 02), contrasting with sibling configurations such as Option 01 which includes a fluorosilicone connector protector, or Option 11 and 12 which utilize FluidLoc cable. The 3300 NSv transducer system operates on eddy-current measurement principles to measure shaft vibration and axial position on targets with limited geometry or clearance, where standard 8 mm probes are too large.

Features

• Option 00 specifies a fully threaded 1/4-28 UNF steel probe body with 0.0 inches of unthreaded length.
• Option 20 provides a 2.0-inch overall case length for standard mounting brackets.
• Option 05 provides a short 0.5-meter (20-inch) integrated lead, designed to connect directly to a 330930 extension cable.
• Option 02 features a miniature coaxial ClickLoc connector with standard (non-armored) coaxial cable.
• TipLoc molding process creates a molecular bond between the PPS probe tip and the AISI 303 stainless steel body.
• CableLoc design withstands up to 220 N (50 lb) of pull strength at the cable-to-probe connection.
• Compatible with the 3300 XL NSv Proximitor Sensor (330980) and 3300 NSv Extension Cable (330930).

Applications

• Small-bore rotating machinery where physical clearance is highly restricted.
• Aeroderivative gas turbines with tight target geometries.
• High-speed centrifugal compressors and pumps requiring non-contact displacement measurements.
• Shaft radial vibration and axial position monitoring on shafts smaller than 13 mm (0.5 in) in diameter.

Installation Guidelines

• Maintain a minimum center-to-center separation of 25 mm (1.0 in) for parallel axial position probes, or 23 mm (0.9 in) for radial vibration probes in X-Y configuration to prevent electromagnetic cross-talk.
• Use a 7/16-inch hex wrench for mounting standard 1/4-28 UNF-2A threaded cases.
• Torque the probe case to mounting brackets according to standard engineering specifications; do not exceed mechanical limits of the threaded AISI 303 stainless steel case.
• Ensure the connection between the probe cable and extension cable is clean, dry, and secure. Apply silicone tape or optional connector protectors if exposed to moisture, but avoid silicone tape if exposed to turbine oil.
