Pressure & Seal Info
- Probe seals differential pressure between tip and case.
- Seal uses a Viton O-ring.
- Probes are not pressure tested before shipping.
- Contact custom design department if you need a pressure test.
Installation Tips
- Use reverse mount design for hard-to-reach areas.
- Keep bend radius larger than 25.4 mm.
- Do not use below -34°C to protect the seal.
- Finger tighten the connector only.

- Shipping: FedEx, UPS, DHL.
- Fast global shipping available.
Typical Uses
- Monitor shaft vibration in turbines and compressors.
- Measure axial position in generators.
- Reverse mount fits where standard probes cannot.
- Helps predict bearing wear and unbalance.
Professional FAQ
- Can I use this probe in a wet area? Yes, but protect the connector from direct water.
- What happens if I overtighten the connector? It may break. Keep it finger tight only.
- Is the 9-meter cable too long for my monitor? No, the 3300 XL system works with 1, 5, or 9 meters.
- Does reverse mount change sensitivity? No, same performance as standard mount probes.
- Can I cut the cable to make it shorter? No. Cutting changes resistance and ruins calibration.
Experience-Based FAQ
- My shaft is smaller than recommended. Any fix? Use a flat target above 30 mm for best results.
- Why does the temp range show -51°C and -52°C? Operating limit is -51°C. Storage can go slightly lower.
- I need a pressure test report. What to do? Request a custom test from Bently Nevada before ordering.
- How do I know if my reverse mount fits? Measure thread depth. M10 x 1 needs 24 mm engagement max.
- Can I use this with non-Bently cables? Not recommended. Use only 75 Ω triaxial FEP cable.
Selection Guide
- Step 1 – Check your space. Reverse mount fits tight areas.
- Step 2 – Confirm thread type. This uses M10 x 1.
- Step 3 – Pick total length. 90 = 9.0 meters for remote use.
- Step 4 – Choose connector. 00 = Miniature ClickLoc.
- Step 5 – Select approval. 00 if not required.
- Step 6 – Verify temp range. Works from -51°C to +177°C.
