Epro PR6424/010-010 Eddy Current Displacement Sensor

Product Description

The PR6424/010-010 sensor from Emerson Electric EPRO portfolio is a non-contact eddy current probe engineered for precise measurement of shaft dynamics in rotating equipment. With a 16 mm probe tip, this sensor is optimized for monitoring radial vibration, axial displacement, and shaft position in critical turbomachinery.

Designed for integration with EPRO signal converters such as the CON0xx series, the PR6424/010-010 forms part of a complete condition monitoring chain compliant with API 670 requirements. Its robust construction and wide operating temperature range allow stable operation in high-speed and high-temperature industrial environments.

Functional Overview

• Non-contact measurement eliminates mechanical wear

• High-frequency response suitable for dynamic vibration analysis
