Sensor type
3300 XL 8 mm eddy-current proximity transducer system (probe + extension cable + Proximitor Sensor)
Fits eddy-current proximity measurement where you need a Bently Nevada 3300 XL 8 mm system. Proximity transducer system (probe + extension cable + Proximitor) with 2 mm (80 mils) linear range, average/incremental scale factor 7.87 V/mm (200 mV/mil) nominal, API 670 compliant 5 m system, recommended gap 1.27 mm, factory calibrated to AISI 4140, standard probe lead to 177 °C (ETR to 218 °C), and backward compatibility with non-XL 3300 5/8 mm components.
Key advantages
- Linear range — 2 mm (80 mils)
- Scale factor — 7.87 V/mm nominal
- API 670 — 5 m system compliant
- Gap — 1.27 mm recommended
- Temp — To 177 °C std; 218 °C ETR
Typical applications
- Shaft vibration/position.
- Proximitor-based monitoring.
- API 670 machinery protection.
Selection guide
- System length
- ETR vs standard
- Target material
Common mistakes
- Wrong system length.
- Non-4140 without scale factor check.
- Gap far from 50 mils.
