The Bently Nevada 330905-00-18-05-02-05, also cataloged as the 330905 Proximity Sensors, operates as a dedicated hardware component for non-contact shaft displacement and dynamic vibration measurement within 3300 NSv Machinery Monitoring System platforms. Utilizing an unarmored M10 x 1 AISI 304 stainless steel threaded housing with 0 mm unthreaded length and 180 mm overall case length, the unit terminates via a 0.5 m (20 in) 75 Ohm coaxial cable with a miniature ClickLoc connector and multiple agency approvals.

Mechanical Monitoring & TSI Performance
The 330905-00-18-05-02-05 transducer operates via high-frequency eddy-current probe scaling to measure real-time rotor dynamics on small-diameter shafts or constrained counterbores. Output voltage changes linearly relative to the physical gap between the PPS probe tip and the observed conductive target. Correct physical positioning requires gap voltage validation targeted at -10 VDC during installation to align the probe within its linear operating range, maintaining low signal cross-talk suppression in high-density multi-channel monitoring arrangements.
Frequently Asked Questions
Q: What gap voltage level verifies correct mechanical installation of the 330905 probe?
A: Adjust probe insertion depth until the output signal measured at the corresponding 3300 NSv Proximitor Sensor reads -10 VDC, centering the probe in its calibrated linear voltage range.
Q: Can the 0.5 m probe cable connect directly to a monitoring cabinet terminal block?
A: No. The integrated 0.5 m (20 in) FEP coaxial cable must couple to a 3300 NSv extension cable to complete the 5.0 m or 7.0 m total calibrated system length required by the Proximitor Sensor.
Q: What material comprises the probe tip insulation on the 3300 NSv series?
A: The tip is constructed from molded Polyphenylene sulfide (PPS), which provides mechanical encapsulation and chemical resistance across temperatures from -34 deg C to +177 deg C.
Field Installation Guidelines
- Thread the M10 x 1 stainless steel casing into the mounting port by hand to prevent cross-threading prior to securing with a wrench.
- Engage a minimum of 5 full casing threads to maintain mechanical locking against high-frequency shaft vibration.
- Keep the FEP-insulated coaxial cable clear of sharp metal edges, tight bend radii, and AC power wiring to prevent noise coupling.
- Inspect and clean all coaxial ClickLoc connector contacts before latching the bayonet connector assembly.
