Overview
The Bently Nevada 21747-040-00 is a Proximitor® probe extension cable designed for use in proximity transducer systems, extending the connection between the proximity probe and its monitoring electronics. It is engineered to maintain accurate gap‑to‑voltage measurements—used for precise shaft position and vibration monitoring on rotating machinery such as turbines, compressors, pumps, and motors.
General Information
Part Number: 21747‑040‑00
Manufacturer: Bently Nevada
Country of Origin: USA
Type: Proximitor Probe Extension Cable
Application: Extending proximity probe connections in machinery condition monitoring systems
