How It Works

The EPRO PR6423/119-110 forms an oscillator circuit when used with the signal converter (CON). As a metallic object moves closer to the sensor, the amplitude of oscillation decreases. This dampening effect directly correlates to the distance between the sensor and the object, allowing precise measurement of displacement.

Thanks to the contactless design, this sensor maintains high accuracy without direct contact with the target, reducing mechanical wear and tear. Moreover, the system arrives fully calibrated, so no on-site adjustments are required except for setting the gap between the sensor and the target object.

Key Features

• Contactless Measurement: The sensor uses eddy current technology, ensuring no physical contact with the target material, which prevents wear.
• High Sensitivity: Offers accurate measurements of small displacements, with a sensitivity of 2 V/mm (50.8 mV/mil).
• Durability: Designed to withstand harsh industrial environments with protection rated at IP65.
• Pre-Calibrated System: The sensor and signal converter arrive fully calibrated, eliminating the need for further setup.
• Wide Temperature Range: Operates effectively within a wide temperature range of -35°C to +180°C (-31°F to +356°F).

Technical Specifications

System Description

The EPRO PR6423/119-110 is designed for precise monitoring of machinery parameters. It works together with a signal converter to form an oscillator circuit. The sensor’s amplitude of oscillation decreases when a metallic object gets closer, allowing the sensor to calculate the exact distance. This provides accurate displacement measurements without any mechanical contact.

The system requires minimal maintenance and setup, with only the gap between the sensor and the object needing adjustment to achieve optimal signal output. This ease of use, combined with the sensor’s rugged construction, makes the EPRO PR6423/119-110 a go-to solution for machine health monitoring.
