Overview
The Emerson EPRO CON011, also cataloged as the CON011 Signal Converter, operates as a dedicated hardware component for eddy current displacement signal conditioning within EPRO machinery protection measurement chains. It processes probe excitation signals from PR642 series sensors and converts them into proportional electrical outputs for monitoring systems.

Eddy Current Measurement Signal Processing
The CON011 module forms the signal conditioning section of an EPRO eddy current measurement loop. The unit supplies high-frequency excitation to compatible PR642 series probes and demodulates the returned electromagnetic signal caused by changes in the probe-to-shaft gap.
The measurement chain uses probe scaling characteristics to convert physical displacement into electrical output. System calibration requires validation of probe gap voltage, signal polarity, and mechanical installation position before connection to machinery protection inputs.
For rotor monitoring applications, the measurement loop supports analysis of shaft movement conditions including radial vibration, axial displacement, and eccentricity. Proper probe alignment and cable routing are required to maintain measurement stability and minimize electrical interference.
Frequently Asked Questions
Q: What type of sensor connects to the CON011 signal converter?
A: The CON011 is designed to operate with compatible EPRO PR642 series eddy current proximity probes. The probe and converter must match the specified measurement characteristics.
Q: Does the CON011 provide direct mechanical displacement measurement?
A: No. The CON011 processes electromagnetic signals generated by the eddy current probe and converts the detected gap variation into an electrical output signal.
Q: What installation factors affect measurement accuracy?
A: Probe mounting position, target surface condition, cable shielding, grounding arrangement, and correct gap adjustment affect the final measurement signal quality.
Field Installation Guidelines
Install the CON011 in a location protected from excessive vibration, contamination, and moisture exposure within the limits of its IP65 enclosure rating.
Connect the PR642 probe using the specified cable arrangement and maintain separation between sensor wiring and high-power switching cables to reduce electromagnetic interference.
Verify the probe installation gap and output polarity before connecting the converter output to a machinery protection system, PLC, or DCS input channel.
Ground cable shields according to the equipment grounding design and avoid multiple grounding points that may introduce unwanted signal loops.
Confirm the complete measurement chain calibration after mechanical installation, including probe position, converter output response, and monitoring system input scaling.
