PR6423/002-111+CON041 Eddy Current Signal Converter

There are some obvious differences between eddy current sensor and preprocessor in features and functions.

The main features of the eddy current sensor are as follows:

Non-contact measurement: The distance between the measured metal conductor and the probe surface can be measured statically and dynamically without contact, with high linearity and high resolution.
Wide measuring range: can accurately measure the static and dynamic relative displacement changes between the measured body (must be a metal conductor) and the probe end face.
Good dynamic response: good long-term reliability, high sensitivity, strong anti-interference ability.
Strong applicability: It can work in oil, gas and certain chemical composition media, and is often used for long-term real-time monitoring of axis displacement, shaft vibration, shaft speed and other parameters of large rotating machinery.
The main characteristics of the preprocessor may be more focused on signal processing and conversion, although the specific type and type of the preprocessor will be different, but in general, the preprocessor plays the role of amplifying, conditioning or converting the output signal of the sensor in the sensor system in order to better adapt to the subsequent data processing or control system.

In summary, eddy current sensor is mainly responsible for non-contact measurement tasks, with wide measuring range, high sensitivity and good dynamic response. The preprocessor is mainly responsible for processing and converting the output signal of the sensor to meet the needs of the subsequent data processing or control system. Both play an important role in sensing and signal processing, and together constitute a complete signal detection and conversion system.
