The EPRO PR6423/002-030 Electrical Vortex Sensor with CON021 preprocessor is a high-precision, non-contact measurement device for the monitoring of physical quantities such as shaft vibration and shaft displacement in rotating machinery. The following are the details and features of the sensor:

Basic information
Model: EPRO PR6423/002-030
Preprocessor type: CON021
Type: Electrical eddy current sensor
Working principle
The eddy current sensor forms an oscillator with the preprocessor CON021, and the amplitude decays as the sensor probe approaches the metal subject.
The amplitude of attenuation is proportional to the distance between the sensor and the measured object, and physical quantities such as shaft vibration are measured by this principle.
Technical parameter
Input: Turbine Sensor PR6422/… ~ PR6426/…
Output: The AC voltage signal superimposed on the DC voltage is proportional to the shaft vibration.
Output voltage linear range: -4… -20V (the supply voltage is -24V).
Output voltage Wide range: -1… -22V.
Output voltage (typical value) : -12V (symmetrical measurement range at both ends).
Internal resistance: 100kΩ.
Response time: 15 (unspecified unit, may be milliseconds or other).
Accuracy:
When the preprocessor CON0X1 (including CON021) is connected to PR6423, the linear error is less than or equal to 1.0%.
Temperature drift (zero point) : 200mV/100K.
Temperature drift (sensitivity) : < 2%/100K.
Time drift: 0.3% Max.
Error of supply voltage: < 0.2%/V.
