Bently Nevada 330104-00-08-90-02-05 8 mm 3300 XL Eddy-Current Proximity Probe

FAQ

Q1: What is the main application of the 330104-00-08-90-02-05 probe?
It is used for non-contact measurement of shaft displacement and position in rotating equipment such as compressors, pumps, and turbines.

Q2: What does each section of the model number mean?
“00” = unthreaded length 0 mm; “08” = 80 mm case length; “90” = 9.0 m total cable length; “02” = armored miniature connector; “05” = CSA/ATEX/IECEx approvals.

Q3: What materials are used in the probe construction?
The probe has a PPS tip and a stainless-steel armored housing for high durability in harsh industrial areas.

Q4: What operating temperature range is supported?
It is designed for –52 °C to +177 °C environments.

Q5: What kind of signal does the probe output?
When paired with a compatible 3300 XL Proximitor, it produces a voltage proportional to the gap between the probe and the shaft surface.

Q6: Is this model suitable for hazardous-area installation?
Yes, the “05” suffix indicates compliance with CSA, ATEX, and IECEx requirements.

Q7: What sensitivity does this proximity probe provide?
It typically offers ~200 mV/mil (≈7.87 V/mm) with a linear measurement range of approximately 0.25–2.5 mm.

Q8: What are the physical size and weight specifications?
The probe case is 80 mm long with an 8 mm tip diameter, and the complete assembly weighs around 1.5 kg with its 9-meter armored cable.
