Product Overview

The Epro PR6423/002-030+CON041 8mm Eddy Current Sensor+Eddy Current Signal Converter is a complete non-contact displacement measurement assembly used for rotating machinery monitoring applications. The system combines an 8mm eddy current sensor probe with a CON041 signal converter to detect shaft displacement, vibration movement, and relative mechanical position changes.

The eddy current measurement principle allows the sensor to monitor rotating components without direct physical contact. This makes it suitable for machines operating at high speed where mechanical contact sensors would experience wear, reduced accuracy, or limited service life.

The PR6423/002-030 sensor detects changes in the distance between the probe tip and the conductive target surface, while the CON041 converter processes the sensor signal into a format suitable for connection with vibration monitoring and machinery protection systems.

This sensor system is commonly installed on critical rotating equipment such as steam turbines, gas turbines, compressors, pumps, and generators where continuous condition monitoring is required.

Working Principle

The Epro PR6423/002-030+CON041 operates through electromagnetic eddy current sensing technology.

A simplified measurement path is:

Rotating Shaft → PR6423/002-030 Sensor Probe → CON041 Signal Converter → Machinery Monitoring System

During operation, the sensor generates an electromagnetic field near the rotating shaft surface. When the gap between the probe and the conductive target changes, the eddy current effect changes accordingly.

The sensor signal is transferred to the CON041 converter, which processes the signal and provides a usable measurement output for vibration monitoring and protection equipment.

Typical monitoring functions include:

• Shaft radial displacement detection
• Vibration amplitude monitoring
• Relative shaft position measurement
• Mechanical condition analysis
• Abnormal movement identification

The non-contact measurement method allows continuous monitoring of rotating components without affecting machine operation.

Role in Machinery Condition Monitoring Architecture

The PR6423/002-030+CON041 operates as a sensing interface within a rotating equipment protection system.

A typical architecture can be represented as:

Rotating Equipment → Eddy Current Sensor → Signal Converter → Monitoring Module → Control / Protection System

Within this architecture:

• The sensor detects shaft movement.
• The converter processes displacement signals.
• The monitoring system evaluates machine condition.
• The protection system responds to abnormal vibration or displacement conditions.

The sensor assembly provides essential mechanical feedback data for equipment reliability management.
