330140-08-50-02-00 | Bently Nevada 5m 8mm Probe

The Bently Nevada 330140-08-50-02-00 is a Probe and extension cable also for industrial control and automation applications.

Bently Nevada 330140-08-50-02-00 is a 3300 XL 8 mm probe without armor, supplied with a 5.0-meter (16.4-foot) total length and a Miniature coaxial ClickLoc connector. Its 0.8-inch case length and 8 mm tip make it a robust choice for continuous vibration monitoring on rotating machinery.

What distinguishes the 330140-08-50-02-00 probe?

This probe belongs to the 3300 XL series, which incorporates patented TipLoc and CableLoc designs. The TipLoc molding method creates a robust bond between the probe tip and body, while the CableLoc design provides 330 N (75 lbf) of pull strength to secure the cable and tip. The 8 mm probe body offers a thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged probe that resists physical abuse. The case is made from AISI 303 or 304 stainless steel.

Key technical parameters

• Total length: 5.0 meters (16.4 feet), designed for use with the 5-meter Proximitor sensor only.
• Connector type: Miniature coaxial ClickLoc connector with standard cable.
• Nominal probe DC resistance: 8.73 ± 0.50 Ω from center conductor to outer conductor.
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% including interchangeability error over the 80 mil linear range from 0°C to +45°C.
• Probe tip material: Polyphenylene sulfide (PPS).
• Operating temperature: -52°C to +177°C (-62°F to +350°F) for the standard probe.
• Weight: 323 g/m (11.4 oz).

Why choose the 8 mm probe design?

The larger diameter of the 8 mm probe body provides a stronger, more robust case compared to smaller probes. Bently Nevada recommends using 8 mm probes when possible to provide optimal robustness against physical abuse. This makes This unit well suited to harsh industrial environments where mechanical stress is a concern. The probe also features a Viton O-ring seal to seal differential pressure between the probe tip and case.

How does the 5-meter length affect system compatibility?

The 5.0-meter total length is specifically designed for use with the 5-meter Proximitor sensor only. This matching ensures the system maintains its specified accuracy. The probe’s ISF of 7.87 V/mm (200 mV/mil) ±5% applies to standard 5 or 1 meter systems when measured in increments of 0.25 mm (10 mils) over the 80 mil linear range from 0°C to +45°C. Deviation from best fit straight line (DSL) is less than ±0.025 mm (±1 mil) under the same conditions.
