EPRO PR6423/015-010 8mm Eddy Current Sensor

Overview

The EPRO PR6423/015-010 is an advanced eddy current sensor designed for precise measurement in critical turbomachinery applications. It measures radial and axial shaft dynamic displacement, as well as position, eccentricity, and speed in various machinery, including steam turbines, gas turbines, compressors, gearboxes, pumps, and fans. With a non-contact measurement principle, this sensor ensures high accuracy, long-lasting performance, and minimal maintenance.

Key Features

Non-Contact Measurement: This sensor uses the eddy current principle, allowing it to detect movement without physical contact, reducing wear and tear.
Precise Displacement and Eccentricity Measurement: The EPRO PR6423/015-010 measures both radial and axial shaft displacement, providing detailed insights into shaft movement.
Versatile Applications: Ideal for use in turbomachinery, the sensor measures a wide range of mechanical parameters, including eccentricity, position, and speed.
Robust and Durable Design: The IP66 rated enclosure and materials, such as stainless steel and PTFE, ensure the sensor performs reliably in harsh industrial environments.
Factory-Set Calibration: The sensor is factory-calibrated, so users only need to adjust the air gap for optimal measurement without requiring complex on-site calibration.
