Epro CON041/SF+PR6423/015-111 Eddy Current Displacement Measurement System

Product Description

The CON041/SF + PR6423/015-111 from Epro is a fully integrated eddy-current measurement system engineered for continuous, non-contact monitoring of shaft dynamics in rotating machinery. This configuration combines a precision 8 mm probe with a DIN-rail mounted signal conditioning module, delivering stable and high-resolution displacement and vibration data under demanding industrial conditions.

The sensing element detects minute changes in shaft position using electromagnetic principles, while the converter processes and scales the signal into industry-standard outputs suitable for control and protection systems. The system is widely deployed in turbomachinery where reliability, fast response, and measurement accuracy are critical.

FAQ

Q: Can this system measure both vibration and static displacement?
A: Yes, the system supports both dynamic (vibration) and static (position) measurements within its linear range.

Q: Is field calibration required after installation?
A: Initial calibration is typically required to set the correct gap and scaling. After that, the system maintains stability with minimal drift.

Q: What monitoring systems is it compatible with?
A: It integrates with Epro MMS 6000, AMS 6500, and other standard PLC/DCS platforms via analog outputs.
