Features:
- Links the PR6423/018-040 Proximity Probe and CON021 Preamplifier to Critical Machinery Monitoring Networks
- Merges Non-contact Displacement Detection with CON021 Signal Conditioning and Conversion
- Coordinates with Turbomachinery Protection and Condition Monitoring Systems
The PR6423/018-040 CON021 Eddy Current Sensor operates as a complete non-contact displacement measurement system, providing reliable proximity signals for all rotating machinery within the monitoring loop. It continuously converts changes in shaft surface distance into precise electrical outputs (measurement range 0 to ±1.0 mm up to ±1.5 mm) and conditions these signals through the CON021 preamplifier to support steady state operation of vibration and position monitoring modules. Seamless signal transfer is standard with the CON021, with the PR6423/018-040 system supporting various cable configurations including armored and non-armored variants with self-locking waterproof connectors or flying lead terminations.
The PR6423/018-040 CON021 provides essential sensing functions common to the entire machinery protection system, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall condition monitoring system. One PR6423/018-040 probe paired with one CON021 signal converter is required per measurement point depending on the desired monitoring coverage. The CON021 occupies only minimal panel space in the instrument cabinet and is always installed in proximity to the associated monitoring system termination points, with the PR6423/018-040 probe mounted at the designated measurement location near the machine bearing housing.
For precision measurement applications, the PR6423/018-040 CON021 system requires factory-matched calibration between the PR6423/018-040 probe and CON021 preamplifier prior to shipment. In addition to standard signal conversion, the CON021 also performs continuous linearity assurance across its 0 to 20 kHz (-3 dB) frequency response with less than 15 μs rise time. The PR6423/018-040 sensor configuration executes accurate displacement measurement using the pre-calibrated response curve specified in the sensor-converter pairing options. Using this method, the measurement system continually monitors the air gap between the PR6423/018-040 probe tip and rotating target surface. If the system detects that the PR6423/018-040 CON021 output deviates from configured linearity/tolerance levels, it will automatically indicate a calibration fault condition and prompt maintenance personnel to verify the installation air gap.
The PR6423/018-040 CON021 EPRO Eddy Current Sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
