Description
Product Overview
The Bently Nevada 3300 XL 8 mm Proximity Probe monitors radial vibration and axial position. Model 330102-00-40-05-02-00 works with Proximitor sensors for reliable rotating machinery protection. It uses a PPS tip and stainless steel case for harsh industrial environments. This probe fits compressors, turbines, pumps, and generators.
For larger shaft applications, see the 3300 XL 11 mm Proximity Probes.

Frequently Asked Questions (FAQ)
Q: Can I use this 0.5m probe with a 9m Proximitor sensor? A: No. Only use with 5m Proximitor sensor.
Q: What happens if I exceed -34°C?
A: Pressure seal may fail prematurely. Keep above -34°C for seal life.
Q: Is this probe pressure tested before shipment?
A: No. Contact custom design department if you need pressure seal testing.
Q: Can I extend field wiring beyond 305 meters?
A: No. Longer runs cause signal rolloff and reduce high frequency response.
Experience-Based Q&A
Q: We see unstable readings on a high-speed compressor. Could it be the cable length? A: Yes. Check total cable length (probe + extension + sensor). Keep within 305 m from sensor to monitor.
Q: Does PPS tip resist steam and water?
A: Yes. PPS handles high humidity and many chemicals. Avoid direct liquid impact if possible.
Selection Guide
- Choose 330102-00-40-05-02-00 for standard 0.5m armored probe with ClickLoc connector
- Select unthreaded length = 00 for flush tip mounting
- Pick overall case length = 40 (4.0 in) for typical mounting fixtures
- Use connector code 02 for reliable miniature coaxial ClickLoc
- For high temperature tips above +177°C, order extended range version
- No agency approval needed for most industrial zones – choose code 00
