Description
Overview
The PR6426/00‑CS (CON01) is an eddy‑current proximity sensor from Emerson’s EPRO series, designed for non‑contact measurement of shaft displacement, vibration, and position in rotating machinery. It forms part of a complete proximity measurement chain used in condition monitoring and machinery protection systems.
Functional Characteristics
This sensor detects changes in the distance between the probe tip and a conductive target surface using eddy‑current technology. Its design ensures stable linearity, low noise, and high repeatability, making it suitable for continuous monitoring of critical rotating assets. When paired with compatible extension cables and CON0x signal converters, it delivers conditioned outputs for diagnostic and protection systems.

Additional Notes
This sensor is not a valve positioner or digital actuator. It is strictly an eddy‑current proximity probe used for vibration and displacement measurement. A complete measurement loop requires a matching extension cable and a CON01 signal converter.
FAQ
Q: What type of measurement does this sensor provide A: It measures non‑contact displacement and vibration using eddy‑current technology.
Q: Does the sensor include the CON01 converter A: No. The converter must be ordered separately.
Q: Can it be used with non‑Emerson monitoring systems A: Yes. When paired with the correct converter, it outputs standard conditioned signals compatible with many third‑party systems.
