Product Overview

The Epro PR6423/002-100-CN 8mm Eddy Current Sensor is a non-contact displacement measurement sensor used for rotating machinery condition monitoring and protection systems. As a member of the Epro PR6423 series, it is designed to detect shaft displacement, vibration movement, and relative position changes in industrial rotating equipment.

The sensor uses eddy current technology to measure the distance between the probe tip and a conductive target surface through electromagnetic field variation. Since the measurement process does not require physical contact with the rotating shaft, the sensor can operate reliably in high-speed machinery applications while avoiding mechanical wear.

The PR6423/002-100-CN is commonly installed on critical equipment such as steam turbines, compressors, generators, pumps, and other rotating machines where accurate shaft monitoring is required. It provides essential displacement signals for machinery analysis, protection logic, and predictive maintenance systems.

In practical maintenance applications, the sensor is often used as the first measurement point in a complete monitoring chain, working together with signal converters and vibration monitoring modules to evaluate machine operating conditions.

Working Principle

The Epro PR6423/002-100-CN operates based on the principle of eddy current displacement sensing.

A simplified measurement process is:

Rotating Shaft → PR6423/002-100-CN Sensor → Signal Converter → Monitoring System

During operation, the sensor generates an electromagnetic field near the conductive shaft surface. When the distance between the sensor tip and the shaft changes, the eddy current response changes accordingly.

The sensor detects these variations and converts them into electrical signals representing shaft displacement. The measurement signal can then be processed by compatible converters and monitoring equipment.

Typical monitoring functions include:

• Shaft radial vibration measurement
• Relative shaft position monitoring
• Mechanical displacement detection
• Rotating equipment condition evaluation
• Abnormal vibration trend analysis

The contactless measurement method enables continuous monitoring without affecting the operation of the rotating machine.

Role in Machinery Condition Monitoring Architecture

The PR6423/002-100-CN functions as a front-end sensing component in rotating machinery protection systems.

A typical system structure can be represented as:

Machine Shaft → Eddy Current Sensor → Signal Converter → Monitoring Module → Protection System

Within this architecture:

• The sensor detects shaft movement and displacement changes.
• The converter processes the sensor output signal.
• The monitoring module evaluates vibration and position data.
• The protection system provides alarms or shutdown responses when abnormal conditions occur.

The sensor plays a key role in providing accurate mechanical feedback for equipment reliability management.
