Description
The Emerson EPRO CON021 + PR6423/01C-030 is an eddy current proximity measurement system designed for non-contact monitoring of shaft displacement, vibration, and position in rotating machinery.
The system consists of:
- PR6423/01C-030 eddy current probe (sensor)
- CON021 signal converter module
Together, they form a complete measurement chain used in machinery protection and condition monitoring systems. The sensor operates on the eddy current principle, enabling precise measurement of shaft movement relative to the probe without physical contact. This system is widely used in turbines, compressors, pumps, fans, and gearboxes in critical industries such as oil & gas, power generation, petrochemical, and heavy industrial automation.
The PR6423 sensor is designed for harsh industrial environments and provides reliable performance under high temperature, vibration, and contamination conditions. The CON021 converter conditions and processes the signal for integration into monitoring and control systems.
