Bently 24765-02-00 Vibration Sensor

Description

Bently 24765-02-00 Vibration Sensor

Product Overview

The Bently Nevada 24765-02-00 is an extension cable assembly designed for eddy current proximity transducer systems (such as the standard 7200 or 3300 series proximity probe systems).

It transfers non-contact position and vibration signals from a proximity probe mounted inside critical rotating machinery directly to a Proximitor Sensor or monitoring rack. Built with precision capacitance and impedance specifications, this cable ensures signal integrity across harsh industrial environments.

Part Number Breakdown & Technical Specifications

Part Number Structure: 24765-AA-BB

• 24765: Base catalog series for Bently Nevada proximity extension cables.
• 02 (AA Option): Cable length option — indicates a 2.0-meter cable length.
• 00 (BB Option): Cable options / armor configuration — Unarmored cable with standard miniature coaxial ClickLoc connectors.

Key Specifications

Key Advantages

• High Signal Integrity: Precision-manufactured electrical length and matched capacitance prevent signal degradation in micro-inch vibration and gap displacement measurements.
• ClickLoc Connector Security: Features specialized locking coaxial connectors that prevent accidental disconnections caused by industrial machine vibration.
• Wide Thermal Range: Temperature-resistant outer jacketing accommodates extreme temperatures found inside turbine housings, bearing pedestals, and gearboxes.
• Seamless Compatibility: Designed to integrate directly into standard Bently Nevada 3300 / 7200 proximity system chains without requiring re-calibration.

Important Installation & Usage Precautions

• Matched System Length: Eddy current proximity transducer systems (Probe + Extension Cable + Proximitor) are calibrated as a complete matched system (typically 5-meter or 9-meter total electrical length). Always verify that the probe, cable length (2.0 m), and Proximitor sensor match the overall system length rating.
• Connector Insulation & Sealing: Wrap all connector junctions with high-temperature silicone self-fusing tape to prevent moisture ingress, oil intrusion, or ground loops against metal conduit.
• Minimum Bend Radius: Do not bend the cable tighter than its specified minimum bend radius (typically 1.0 in or 25.4 mm) to prevent damaging the internal coaxial shielding and altering electrical capacitance.
• Routing & Mechanical Protection: Because the -00 option is unarmored, route the cable inside flexible conduit or protective cable trays to guard against physical pinch points, sharp edges, or hot steam pipes.

Applications

• Turbomachinery Monitoring: Used in steam turbines, gas turbines, and hydro turbines to transmit shaft vibration and axial thrust position measurements.
• Centrifugal Compressors & Pumps: Monitors journal bearing oil film thickness and dynamic shaft movement in high-speed process equipment.
• Heavy Gearboxes & Generators: Connects internal proximity probes to external junction boxes in power generation and petrochemical facilities.
• Condition Monitoring Systems: Interfaces directly with Bently Nevada 3500 and 1900 series machinery protection racks.
