Product Description
Overview
The CON021 | 913-040 is a high-performance signal converter designed to interface with the PR6424/000-000 eddy current displacement sensor. This assembly provides precise, non-contact measurement of radial and axial motion in high-speed rotating machinery, including turbines, compressors, and industrial pumps. Operating on eddy current principles, the system detects minute changes in shaft position and converts these signals into standardized analog voltage outputs suitable for machine monitoring systems or distributed control systems.
The PR6424/000-000 sensor is engineered for extreme industrial environments, offering robust resistance to temperature fluctuations, pressure, and exposure to oils or chemicals. Together, the converter and probe provide a reliable, high-resolution measurement solution for vibration and displacement monitoring.
