Product Introduction
The Bently Nevada 21747-045-00 is a precision-engineered probe extension cable that serves as a vital component in proximity transducer systems. It belongs to the highly reliable 7200 series family and is designed specifically to extend the distance between the proximity probe and the proximitor sensor without any degradation in signal quality.
This model offers a total cable length of 4.5 meters (approximately 14.76 feet), making it ideal for installations where longer distances between the probe and monitoring hardware are required. Constructed using robust coaxial cable materials, the 21747-045-00 is engineered to function reliably in high-temperature, high-vibration, and electrically noisy environments, typically found in power generation, oil and gas, petrochemical, and other heavy industrial applications.
Bently Nevada’s reputation for durability, precision, and quality assurance is embedded in every aspect of this cable’s design. It is frequently used in applications involving the monitoring of critical rotating equipment such as turbines, compressors, and large motors.
