Quick Detail

Description

The 21747-045-01 Proximitor Probe Extension Cable is a high-performance, dedicated link engineered to ensure signal integrity and system reliability in critical machinery monitoring applications. Designed and manufactured by Bently Nevada, a global leader in asset condition monitoring, this extension cable serves as a vital conduit between sensitive proximity probes and monitoring system electronics. It is engineered specifically to maintain the precision of vibration and displacement measurements across its entire 4.5-meter length, preserving the linearity and sensitivity of the signal from probe to monitor.

A core feature of the 21747-045-01 model is its comprehensive Agency Approval Option, which includes CSA, ATEX, and IECEx certifications. This suite of global safety approvals certifies the cable for deployment in hazardous locations where flammable gases, vapors, or combustible dusts may be present. This pre-certification provides immense value, enabling engineers to confidently specify and install this extension cable in oil & gas refineries, petrochemical plants, and offshore platforms without the need for additional protective conduits or complex safety validations. The cable is constructed to withstand a demanding operating temperature range of -51°C to +171°C, ensuring stable electrical performance in environments with extreme thermal cycling, such as near steam turbines or in outdoor arctic conditions.

Applications

This cable is essential for bridging the distance between proximity probes mounted directly on machinery and their corresponding monitors located in control rooms or remote junction boxes. Its 4.5-meter length is ideal for applications on mid-sized to large industrial equipment such as compressors, turbines, and large pumps, where the sensor cannot be located immediately adjacent to the monitoring electronics, ensuring signal fidelity is maintained over the required run.

Certified with CSA, ATEX, and IECEx approvals, the cable is specifically designed for safe operation in classified hazardous areas. It is routinely deployed in chemical processing facilities, natural gas compressor stations, and on offshore drilling platforms to extend signals from vibration and position probes, enabling compliant monitoring of critical machinery health without compromising intrinsic safety standards in explosive atmospheres.

The cable’s wide operating temperature range (-51°C to +171°C) and durable construction make it suitable for challenging environmental conditions. It can be routed through hot engine rooms, along high-temperature steam lines, or in cold outdoor installations, providing a reliable signal path for predictive maintenance systems that monitor equipment performance across extreme thermal variations.

Specifications

Competitive Advantage

1. Pre-Certified Global Hazardous Area Safety

Unlike generic coaxial cables, the 21747-045-01 arrives with a comprehensive set of CSA, ATEX, and IECEx certifications. This provides a significant competitive edge by eliminating the time, cost, and engineering overhead associated with obtaining site-specific safety approvals. It offers a ready-to-install, globally compliant solution that accelerates project timelines and ensures regulatory compliance for multinational operations.

2. Patented ClickLoc Connector for Ultimate Reliability

Featuring the proprietary Miniature coaxial ClickLoc connector system, this cable ensures a secure, vibration-proof connection that is both tactile and audible. This design provides a decisive advantage over traditional threaded or push-on connectors, which are prone to loosening under machine vibration, potentially causing intermittent signal loss and unreliable monitoring data. The ClickLoc system guarantees a persistent, high-integrity connection.

3. Optimized Flexibility for Simplified Installation

Configured Without Stainless Steel Armor, this specific model is significantly more flexible and lightweight than armored alternatives. This enhanced flexibility allows for easier pulling through conduits, tighter bending in crowded cable trays, and simpler overall handling during installation. This reduces labor time, minimizes installation stress on the cable and connectors, and provides a cleaner, more manageable installation in space-constrained industrial environments.
