EPRO PR6423/156-110 Eddy Current Transducer

Overview

The EPRO PR6423/156-110 eddy current transducer system is designed to provide precise, non-contact measurements of mechanical parameters such as displacement and vibration. Its rugged construction and compact size make it ideal for use in harsh industrial environments, particularly in the monitoring of turbomachinery and similar high-performance systems. This system measures key parameters, ensuring reliable operation and early detection of potential mechanical issues.

Key Applications

The EPRO PR6423/156-110 transducer system is commonly used in a variety of industrial and laboratory settings. Some of its most frequent applications include:

Clearances between rotating and stator parts
Vibration of rotating and stationary components
Dynamic motion and eccentricity of shafts
Deformation or bending of rotating or stationary parts
Axial and radial shaft movements
Thrust bearing positions and wear detection
Oil film thickness measurement
Differential expansions between components
Housing expansions and valve positions

These applications help to prevent damage and optimize the efficiency of turbines, motors, and other rotating machinery.

How It Works

The EPRO PR6423/156-110 uses an eddy current measurement principle, which relies on electromagnetic fields to detect the proximity of metallic objects. As the transducer detects changes in the distance to the measured object, it adjusts its oscillation amplitude accordingly. This oscillation damping is proportional to the distance between the transducer and the object. The system comes pre-calibrated, ensuring ease of installation and minimal maintenance. Users only need to adjust the gap between the sensor and the object to obtain accurate measurements.

Benefits

Non-contact measurement: The sensor eliminates wear on components, making it a cost-effective solution for long-term use.
Compact and rugged: Designed for high durability, the EPRO PR6423/156-110 operates reliably in extreme conditions.
Pre-calibrated: The system arrives fully calibrated, so users can install it without performing on-site calibration.
Versatile applications: Suitable for monitoring a wide range of parameters on rotating machinery, improving predictive maintenance.
