Bently Nevada 84661-50 Interconnection Cables

Description

The 84661-50 is a standard interconnect cable assembly designed for use with Bently Nevada High Temperature Velomitor (HTVS) systems. This shielded, 0.382 mm squared (22 AWG) cable provides the necessary link between the HTVS sensing head and the signal conditioning electronics, enabling remote placement of electronics in cooler environments to ensure consistent measurement performance in high-temperature machinery applications. This specific 84661-50 configuration features a moisture-resistant female connector at the HTVS end and ring lugs at the monitor end, providing a reliable connection for casing vibration monitoring. It supports operating temperatures from -29 degC to 121 degC (-20 degF to 250 degF). The system design minimizes noise interference and supports cable runs up to 305 meters (1000 feet) without signal degradation.

Features

• Standard configuration: Shielded 0.382 mm squared (22 AWG) conductor
• Connectors: Moisture-resistant female connector (HTVS end) and ring lugs (monitor end)
• Compatibility: Designed specifically for use with 330750 and 330752 High Temperature Velomitor systems
• Temperature Range: -29 degC to 121 degC (-20 degF to 250 degF)
• Signal Integrity: Double-shielded construction to minimize noise interference in industrial environments

Applications

Used in high-temperature machinery environments, including:

• Power generation equipment
• Oil and gas rotating machinery
• Casing vibration monitoring on compressors and turbines
• Harsh industrial environments requiring remote signal conditioning

Installation Guidelines

• Ensure the cable is routed away from high-voltage lines or sources of electromagnetic interference to prevent signal noise.
• The mating part of the connector should provide IP54 ingress protection or better in accordance with IEC 60079-0 requirements.
• Secure the cable using appropriate mounting clamps to prevent mechanical strain on the connectors.
• Verify that the total cable length does not exceed the system limitations for signal integrity (maximum 305 meters / 1000 feet).
