Product Description

Overview

The CON021 | 914-100 signal converter paired with the PR6423/010-010-CN eddy current sensor provides high-precision, non-contact measurement of shaft displacement and vibration. This combination is engineered for critical rotating machinery such as steam turbines, large motors, and generators. Utilizing electromagnetic induction, the system converts subtle variations in gap distance into a linear analog voltage output, delivering reliable data for machine monitoring and protection systems.

Core Technical Features

High Sensitivity and Accuracy

• Detects sub-micron displacement and vibration variations.

• Essential for early fault detection in high-speed machinery.

Non-Contact Measurement

• The eddy current probe measures shaft motion without mechanical contact.

• Prevents sensor wear and eliminates interference with machine operation.

Exceptional Linearity

• The converter maintains a consistent voltage response across the full measurement range (typically 2.0 mm).

• Standard output range is -2V to -18V, ensuring precise correlation between physical displacement and electrical signal.

Industrial Reliability

• Operating temperature: Probe head withstands high temperatures near bearings.

• Pressure-resistant design suitable for lubricated and pressurized environments.

• Materials resist oil, hydraulic fluids, and common industrial chemicals.

Versatile Monitoring

• Supports both static measurements (axial shaft position) and dynamic measurements (radial vibration, eccentricity).

• Compatible with machine monitoring and control systems for real-time condition assessment.
