Bently Nevada 330102-24-48-05-01-00 3300 XL 8 mm Proximity Probe

Product Overview

The 330102-24-48-05-01-00 is a 3300 XL 8 mm Proximity Probe from Bently Nevada. It features a polyphenylene sulfide (PPS) probe tip and a 303 or 304 stainless steel case. The unthreaded length is 2.4 inches, overall case length is 4.8 inches, and total cable length is 0.5 meter (1.6 feet). It uses a miniature coaxial ClickLoc connector with connector protector and standard cable. This probe is designed for radial vibration and position measurement in turbo-machinery.

Technical Specifications Breakdown

Key parameters for the 330102-24-48-05-01-00 are listed below for quick reference:

Industry Applications

The PPS tip and stainless steel case withstand high temperatures and corrosive atmospheres. The 2 mm linear range provides precise shaft displacement data for predictive maintenance programs, reducing unplanned outages.

Installation & Setup Guidance

Mount the probe with the 3/8-24 UNF thread into a suitable mounting block. Ensure the maximum thread engagement is 0.563 inches. Use 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² or 16 to 24 AWG). The maximum field wiring length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). Set the initial gap to approximately -9 Vdc (1.27 mm) for radial vibration measurements.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage or wear. Avoid exposing the probe to temperatures below –34˚C (–30˚F) to prevent premature pressure seal failure. The probe is designed to seal differential pressure between tip and case using a Viton O-ring. Contact the custom design department if pressure testing is required.

Are You Struggling with Reliable Vibration Monitoring in Harsh Environments?

Accurate proximity measurement is critical for protecting rotating machinery. The Bently Nevada 330102-24-48-05-01-00 3300 XL 8 mm Proximity Probe delivers precise, stable readings even under extreme conditions. This component is engineered for demanding applications where sensor drift or failure leads to costly downtime.

Compatibility & Integration

This probe works with Bently Nevada 3300 XL Proximitor Sensors and compatible monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc.

Selection Guide & Purchasing Advice

When selecting a replacement probe, verify the thread size, cable length, and connector type. The 330102-24-48-05-01-00 is available at AutoDCSTech. Please verify current lifecycle status and availability with AutoDCSTech before ordering. Our team can help match the correct probe to your application.

Troubleshooting & Common Issues

If readings are erratic, check the cable for breaks or corrosion. Verify the probe gap is within the linear range (0.25 to 2.3 mm). Ensure the target surface is clean and free of runout. For resistance issues, measure the probe DC resistance; it should be 7.45 ± 0.50 Ω for a 0.5 m probe.
