Product Introduction
The Bently Nevada 330101-00-12-05-01-00 is a 3300 XL 8 mm Proximity Probe with an integral cable. It is a non‑contact eddy‑current probe designed for precision measurement of shaft relative vibration, axial (thrust) position, eccentricity, and speed (Keyphasor) on rotating machinery. This model features a standard 8 mm probe tip with a 120 mm overall case length (suitable for deeper mounting holes or extended reach), a 0.5 meter integral cable, and a Mini‑type coaxial male connector. The -00 suffix indicates no hazardous area approvals, making it suitable for general industrial (safe area) installations. The probe is fully compatible with 3300 XL Proximitors (e.g., 330180 series) and extension cables.
The part number breaks down as follows:
330101 – 3300 XL 8 mm probe (standard configuration)
00 – Unthreaded length: 0 mm
12 – Overall case length: 120 mm (12.0 cm / 4.72 in)
05 – Total cable length (probe + integral): 0.5 m (19.7 in)
01 – Connector type: Miniature coaxial male (Mini‑Type), Option 01
00 – Approval code: No hazardous area approvals (general purpose)
The probe body is constructed from PPS (Polyphenylene Sulfide) and 300 series stainless steel, offering excellent chemical and abrasion resistance. The integral cable uses a fluoropolymer jacket for durability.

Application Scenarios
Deep Mounting Holes or Thick Casings – The 120 mm case length is ideal for machines with thick bearing housings or deep threaded probe mounts, such as large steam turbines, gas turbines, or compressors where a standard 50 mm or 80 mm probe would not reach the shaft surface.
General Industrial (Safe Area) Machinery – Used in power plants, steel mills, paper mills, and manufacturing facilities where no explosive atmospheres are present. The
-00approval makes it a cost‑effective choice for non‑hazardous environments.Radial Vibration Monitoring – Measures shaft‑relative vibration on large pumps, fans, blowers, and electric motors, enabling detection of imbalance, misalignment, and bearing wear.
Axial (Thrust) Position Measurement – Monitors rotor displacement on compressors and turbines to prevent thrust bearing overload and rotor‑stator rub in non‑hazardous areas.
Keyphasor / Speed Reference – Provides a once‑per‑revolution timing pulse for phase measurement, Bode plots, and overspeed detection on industrial machinery.
Short Cable Run (0.5 m) – The 0.5 meter integral cable is suitable when the proximitor can be mounted very close to the probe (e.g., directly on a nearby junction box or bracket), minimizing cable length and cost.
