The 3500/45 position monitor provides critical insights into the physical state of rotating shafts. It features programmable alarm setpoints that allow operators to define danger thresholds for machine displacement. With its integration into the 3500 rack backplane, it communicates position data and alarm status seamlessly to other modules, facilitating automated trip sequences when machines exceed safe operating parameters. The module is built for continuous, 24/7 industrial service, ensuring long-term measurement stability even in complex, high-vibration environments.
A: The module is designed to interface with Bently Nevada eddy current proximity probes, which are the industry standard for measuring shaft displacement and position without physical contact.
A: Yes, the 3500/45 is highly configurable via the 3500 Rack Configuration Software, allowing it to be tailored to specific applications like axial position, differential expansion, or rod position based on the required probe arrangement.
