FAQ

Q: Can this probe measure both static and dynamic signals?
A: Yes, it accurately monitors shaft position (static) and vibration (dynamic) using eddy-current technology.

Q: What does the “18” in the part number indicate?
A: It defines the probe cable length of 1.8 meters.

Q: Is this probe compatible with other Bently Nevada systems?
A: It is fully compatible with the 3300 Series machinery protection systems, including vibration and Keyphasor® monitoring modules.

Q: How does this probe differ from the 330903‑00‑21‑10‑02‑05 model?
A: The 330905 model features an 11 mm probe tip (larger than the 330903’s 8 mm), making it more suitable for larger shaft diameters and heavy-duty applications.
