This measurement chain is a matched set designed for non-contacting displacement measurement. ThePR6423 eddy current probe detects shaft movement, and the CON021 converter translates those movements into a linear voltage signal. This specific configuration is calibrated for a 10-meter system length, which is essential for accuracy in large machinery where the converter is mounted in a remote cabinet.
Component 1: CON021/914-100 Signal Converter
The CON021/914-100 is the driver/transmitter. The "100" suffix specifically identifies its calibration settings, most importantly the total length of the cable it expects to drive.
Model: CON021/914-100
System Length: Calibrated for10 meters
Output Signal: Typically converts displacement to a standardized 0 to -20 VDC signal.
Oscillator Frequency: Generates the high-frequency carrier signal for the probe.
The PR6423 is an 8 mm tip eddy current sensor. The nomenclature "010-010" defines its physical build and integral cable.
Model: PR6423/010-010-CN
Tip Diameter: 8 mm.
Measuring Range: 2.0 mm (nominal).
Integral Cable: 1.0 meter (identified by the first "010").
Protection: The second "010" often signifies an armored conduit for mechanical protection of the cable.
"CN" Suffix: Indicates compliance with specific regional standards (often GB/T standards for the Chinese market) or specific connector variations.
Key Performance Characteristics
Sensitivity: Typically8 V/mm (200 mV/mil).
Linearity Range: Provides a highly accurate window of measurement, typically from -2 VDC to -18 VDC of the output signal.
10m Matching: This convertermust be used with exactly 10 meters of total cable. Using a 5-meter setup with this "100" series converter will result in significant measurement errors and non-linearity.
Environmental Durability: The sensor is rated for high-pressure environments and is resistant to hot lubricating oils, making it ideal for bearing-pedestal mounting.
