Bently Nevada 330100-50-01 3300 XL 8mm Proximity Probe

Technical properties, case dimensions, and core scaling options for the Bently Nevada 330100-50-01 3300 XL 8mm proximity probe. Available as Brand New, Original Stock with Global Shipping.
Description
The Bently Nevada 330100-50-01, also cataloged as the Bently Nevada 330100 Proximity Transducer Probe, operates as a dedicated hardware component for non-contacting shaft displacement and dynamic vibration measurement within machinery protection networks. The threaded sensor tip utilizes eddy-current principles to observe physical gap variations relative to a moving target. Consequently, the probe passes raw high-frequency electrical fields back to a localized Proximitor sensor without introducing phase shift or transmission packet latency.

Machinery Monitoring and TSI Characteristics
The internal coil structure stabilizes loop impedance variables to facilitate precise eddy-current probe scaling configurations across high-velocity machine trains. Therefore, the physical gap layout supports real-time gap voltage validation (-10 VDC targets) within the center of the 2.0 mm linear window to confirm optimal physical sensor centering. Furthermore, the robust coaxial shield layout supplies strict cross-talk suppression between adjacent probe lines. As a result, this isolation blocks inductive noise fields from corrupting raw telemetry tracks to secure clear calculation of complex rotor dynamics.
Frequently Asked Questions
Q: Can maintenance teams replace or service this proximity probe while the machinery loop is under power?
A: Yes, operators can disconnect the miniature coaxial connector string while the core monitoring rack remains powered. However, breaking the sensor circuit creates an instant open-circuit fault; therefore, operators must place the matching tracking channel into bypass mode beforehand to eliminate the risk of accidental plant trips.
Q: What happens if this probe is mounted facing a material other than AISI 4140 steel?
A: Operating the sensor against a non-standard target shifts the electromagnetic response and skews the nominal 200 mV/mil scale factor. Consequently, the calibration profile will drift, necessitating custom bench re-calibration to maintain accurate machinery protection metrics.
Field Installation Guidelines
- Thread the probe body smoothly into the mounting bracket, adjusting the physical position until a calibrated digital voltmeter reads a target baseline of -10 VDC across the sensor loop.
- Tighten the localized locknuts firmly against the mounting bracket assembly to lock the position, ensuring that the sensor tip cannot back out under heavy machine vibration.
- Apply localized protective sleeving or connector boxes over the miniature coaxial links, taking care to isolate the outer shield layer from touching any machine frame ground tracks.
- Separate external transducer signal links from active alternating current transmission conduits by a minimum spatial clearance of 300 mm to suppress inductive noise coupling.
