Bently Nevada 330172-00-20-10-02-05 3300 Series Eddy-Current Proximity Probe

FAQ

Q1: What is the Bently Nevada 330172-00-20-10-02-05?
A1: It is a 5 mm eddy-current proximity probe used for non-contact measurement of shaft displacement and vibration in rotating machinery condition monitoring systems.

Q2: What do the model code segments mean (e.g., “20”, “10”, “02”, “05”)?
A2: “20” indicates a rigid body length of ~2.0 in (~51 mm); “10” designates a 1.0 m integral cable; “02” identifies the miniature coaxial ClickLoc connector; “05” denotes the standard industrial approvals.

Q3: What system does this probe integrate with?
A3: It is designed to work with Bently Nevada 3300 proximitor sensors and extension cables for complete vibration and shaft position monitoring.

Q4: What is the sensing range of this probe?
A4: It typically provides a linear sensing range from around 0.25 mm to 2.0 mm (10–80 mils), depending on system and gap settings.

Q5: What type of signal does this probe output?
A5: The probe outputs a raw analog voltage proportional to the gap/displacement, which must be conditioned by a proximitor or monitoring electronics.

Q6: What environments can this probe operate in?
A6: With its stainless steel body and industrial cable, it is suitable for harsh industrial environments and wide temperature variations.

Q7: How is the probe physically mounted?
A7: The probe is threaded into a housing or mounting block using its 1/4-28 UNF threaded section for stable installation.

Q8: What additional components are needed to use this probe?
A8: To form a complete measurement system, you need a compatible proximitor sensor and, if required, extension cables and condition monitoring electronics.
