330901-00-09-10-02-05 1.0m Proximity Probe Bently Nevada

Product Overview

The 330901-00-09-10-02-05 is a high-precision 3300 NSv Proximity Probe manufactured by Bently Nevada (Made in the U.S.A.). Engineered for fluid-film bearing machines, small-diameter shafts, and confined installation spaces, this eddy current transducer sensor provides precise vibration and position feedback. Featuring a 1/4-28 UNF thread profile with a 0.9-inch overall case length and an unarmored 1.0-meter integrated cable, this probe incorporates a miniature coaxial ClickLoc connector and holds multiple international agency approvals for deployment in critical industrial monitoring networks.

Key Advantages

• Robust Material Composition: Constructed with an AISI304 Stainless Steel case and a high-performance Polyphenylene Sulfide (PPS) tip to withstand harsh operational conditions and corrosive process chemicals.
• Miniature ClickLoc Connectivity: Outfitted with a premium miniature coaxial ClickLoc connector paired with a 75 Ω fluoroethylene propylene (FEP) insulated cable, ensuring reliable and secure data logging loops.
• Flexible Industrial Weight: Possessing a lightweight modular footprint spanning 14 to 150 g (0.5 to 5.3 oz) based on specific configuration extras, it adapts easily to fine brackets without causing structural displacement.
• Differential Pressure Sealing: Features a built-in Viton O-ring seal configured to protect internal hardware gaps by blocking differential pressure migration between the sensor tip and the main case body.

Technical Specifications

Quick Installation Tips

• Tightening Torque Compliance: When mounting the 1/4-28 case, never exceed the maximum rated torque limit of 7.3 N•m (65 in•lb). The manufacturer recommends a stable installation torque of 5.1 N•m (45 in•lb) to prevent structural warping.
• Thread Engagement Control: Carefully limit your absolute mechanical thread insertion depth to a maximum engagement length of 0.375 inches to preserve target clearances and protect the probe face.
• Low-Temperature Handling Alert: Avoid exposing this component to sustained temperatures below -34°C (-30°F). Sustained sub-freezing exposure can lead to micro-brittleness or premature failure of the integrated pressure seal.
• Weight-Strain Relief: Secure the 14 to 150 g cable structure cleanly to nearby machine frames using non-crimping brackets to shield the ClickLoc termination point from excessive pull or drag.

Technical FAQs

Q1: What is the primary purpose of the Viton O-ring within the probe's case body?

A1: The Viton O-ring acts as a reliable differential pressure seal between the probe tip and the exterior case structure, preventing lubricating oil or process gases from leaking through the machine casing. Note that these units are not pre-tested for pressure limits before shipping.

Q2: How do I verify if the 1.0-meter probe cable has experienced an internal open circuit?

A2: You can perform a quick diagnostic check with a standard digital multimeter. Measure the DC resistance from the center conductor to the outer conductor at the ClickLoc terminal connector; a healthy 1.0-meter module should return a reading within the 4.2 ± 0.5 Ω range.

Q3: Why does the documentation specify a variable weight range of 14 to 150 grams?

A3: The base weight starts near 14 g for the standalone bare probe tip and short-case section. The total weight can scale up toward 150 g depending on your chosen configuration options, such as the total extended cable length and the type of connectors attached.
