Bently Nevada 21747-040-00 7200 Series Extension Cable

Description

The 21747-040-00 is a 7200 series extension cable designed for use with Bently Nevada proximity transducer systems. This configuration features a 4.0 metre total length (Option 040) and is supplied without stainless steel armor (Option 00). As a critical component in the 7200 series signal chain, this cable connects the proximity probe to the Proximitor sensor, maintaining the necessary impedance and signal integrity required for accurate vibration and axial position measurements in rotating machinery.

This extension cable is compatible with 7200 series 5 mm and 8 mm proximity probe systems. The design utilizes 95 ohm coaxial construction, ensuring stable performance in various industrial environments. By providing a connection between the probe and the Proximitor, this extension cable allows for flexible installation in turbine, compressor, and pump monitoring applications.

Installation Guidelines

Ensure that coaxial cables are routed away from high-voltage lines to prevent electromagnetic interference. Protect connectors from moisture and contaminants during installation. While this specific model is unarmored, ensure the cable is secured and not subject to sharp bends or excessive mechanical strain. Maintain clean, tight connections at both the probe and Proximitor interfaces to ensure measurement accuracy.
