Description
Product Description
Overview
The Emerson EPR0PR6453/240-101 is a high-precision eddy-current proximity sensor engineered for non-contact measurement of shaft displacement and vibration in compact rotating machinery. Its compact design allows installation in confined spaces while maintaining high sensitivity for small-diameter shafts. This sensor is part of the PR6453 series and is commonly integrated with EPRO signal conditioners, including the CON021 and CON41, creating a reliable measurement chain for machinery diagnostics and protection systems.
Operating Principle
The sensor operates using eddy-current technology to monitor changes in the distance between the probe tip and a conductive rotating surface. These variations are converted into electrical signals proportional to shaft movement. When paired with a compatible signal conditioner, the system provides stable, linearized outputs suitable for condition monitoring platforms and automated control systems.
