FAQ

Q: What is a standard-mount proximity probe?

A: It’s a sensor that uses eddy-current sensing to detect tiny changes in distance between the probe tip and a metallic shaft surface without touching it. The resulting signal reflects shaft vibration and displacement, which machine monitoring systems use for diagnostics and protection.

Q: What does “21504-000-012-10-02” actually mean?

A: Bently Nevada part numbers encode configuration details:

• 21504: Base model of standard mount probe in the 7200 sensor family.
• 000: Zero unthreaded length before standard thread.
• 012: Short case length (~12 mm).
• 10: Cable length ~1.0 m integrated lead.
• 02: With miniature male coaxial connector.

Q: What kind of systems does this probe work with?

A: It typically connects to Proximitor amplifiers or vibration monitors (such as Bently Nevada 3300 or 9000 series or third-party conditioners) that can accept eddy-current proximity inputs.
