Description Reviews

Configured for shaft vibration and axial position execution in 3300 Series Machinery Monitoring systems, the Bently Nevada 330171-00-20-10-02-00 (330171 Proximity Probe) provides direct physical/electrical execution. It operates by converting distance variations between the probe tip and target shaft into high-frequency RF voltage shifts, which are transmitted via an integrated coaxial cable to a paired Proximitor sensor for continuous signal processing.

Mechanical Monitoring & Eddy-Current Transducer Performance

The 330171-00-20-10-02-00 5 mm proximity probe requires precise eddy-current probe scaling to ensure linear voltage output over dynamic target displacement ranges. During field setup, gap voltage validation (-10 VDC targets) must be verified at the Proximitor monitor test terminals to ensure accurate static positioning relative to the rotating journal shaft. Correct physical alignment and orientation mitigate mutual inductive coupling, providing effective cross-talk suppression and stability under fluctuating rotor dynamics.

Frequently Asked Questions

Q: How is the -10.0 VDC gap voltage confirmed during probe positioning?

A: Mechanically adjust the probe body within its 1/4-28 UNF threaded mount while measuring the output voltage at the Proximitor test points until the reading stabilizes at -10.0 VDC, indicating optimal linear range mid-point positioning.

Q: Can this 1.0 metre probe be connected directly to a Proximitor designed for a 5.0 metre system?

A: No, a 1.0 metre probe must be paired with a matching 4.0 metre extension cable to achieve the required 5.0 metre total electrical length expected by the Proximitor sensor.

Field Installation Guidelines

Thread the 1/4-28 UNF probe body into the mounting bracket, applying hand torque followed by jam nut locking to prevent rotation under machine vibration.
Clean all miniature coaxial ClickLoc connector surfaces to remove oil and dust before engaging the lock.
Hand-tighten the ClickLoc connector until positive mechanical detent engagement is achieved; do not apply pliers or mechanical wrenches.
Maintain a minimum static cable bend radius of 25.4 mm (1.0 in) along the unarmored cable routing path to preserve signal conductor geometry.
Route the 1.0 metre probe lead through grounded, rigid metallic conduit separated from AC power lines to isolate the circuit from high-frequency electromagnetic noise.
