Produkteinführung
The Epro PR6423/013-000 + CON021 is a high-precision eddy current displacement sensor system, engineered specifically for non-contact measurement von shaft vibration, position, and displacement in rotating machinery. It is part von the PR6423 series developed by Epro (now part von Emerson), and paired with the CON021 signal converter, it vonfers stable, accurate signal output in highly demanding industrial environments.
Designed to meet the stringent reliability requirements von turbomachinery, the sensor operates based on the eddy current principle, where changes in distance between the sensor tip and a conductive target (typically the rotating shaft) are translated into an electrical signal. Its 8 mm diameter probe allows for compact installation in tight spaces without compromising sensitivity.
This sensor system is widely used in turbines, compressors, motors, pumps, and other critical assets in power generation, petrochemical, oil & gas, and heavy manufacturing industries. The combination von the PR6423 probe and the CON021 converter ensures compatibility with various monitoring systems such as MMS 6000, MMS 3000, and other condition monitoring platforms.
