Bently Nevada 330901-02-24-10-01-00 High-Precision Proximity Probe for Small Shafts

Product Overview

The Bently Nevada 330901-02-24-10-01-00 is a high-performance, non-contact proximity probe designed specifically for the 3300 NSv (Narrow Side View) Transducer System. This specialized sensor measures static and dynamic distance variations between the probe tip and a target conductive surface, such as a rotating machine shaft. Unlike standard larger probes, the NSv series addresses demanding industrial configurations where tight spaces, minimal target size, or small shaft diameters limit standard sensor placement.

Application and Operation

Industrial operators deploy this proximity probe primarily on critical rotating machinery that features compact geometry or strict clearance limitations. Typical applications include small centrifugal compressors, high-speed turbochargers, small pumps, and industrial fans. The probe utilizes eddy current technology to track radial vibration, axial position, and rotational speed without ever making physical contact. By transmitting precise displacement signals to a 3300 NSv Proximitor Sensor, this probe enables predictive maintenance teams to evaluate fluid-film bearing health and intercept mechanical faults before damage occurs.

Technical Characteristics and Breakdown

The part number structure 330901-02-24-10-01-00 defines a precise mechanical layout optimized for specific machinery casings and environment constraints:

• Unthreaded Length: Features a 0.2-inch unthreaded portion, ensuring a highly compact shoulder area for tight brackets.
• Overall Case Length: Measures 2.4 inches in total case length, providing structural stability when passing through thin casing walls or small mounting targets.
• Total Length: Equipped with a 1.0-meter (approximately 3.3 feet) integrated coaxial cable, which bridges the gap between the target location and an external connection box.
• Connector Option: Configured with a miniature coaxial ClickLoc connector to enable secure, low-impedance electrical signal transmission.
• Fluid-Tight Armor: Includes a standard cable design without heavy external armor, making it flexible and easy to route through small conduit passages.
• Hazardous Area Approvals: Carries comprehensive international certifications (such as ATEX, IECEx, and CSA), authorizing safe installation within volatile chemical and hazardous industrial environments.
