EPRO CON021+PR6424/000-030 Proximity Sensor System

The Epro CON021+PR6424/000-030, also cataloged as the PR6424 Eddy Current Displacement Sensor paired with the CON021 Signal Converter, operates as a dedicated hardware component for non-contacting shaft displacement tracking within turbomachinery protection systems. The integrated assembly provides direct physical/electrical execution to monitor radial vibration, axial position, and structural displacement across turbines, compressors, and pumps. It maps physical micro-displacements into linear voltage variations natively at the hardware tier to drive real-time machinery safety loops.

Mechanical Monitoring & TSI Features

• Eddy-Current Probe Scaling and Scale Factor Calibration The PR6424 sensor radiates a high-frequency electromagnetic field from its tip into the targeted ferromagnetic steel shaft. As mechanical gap distances fluctuate, eddy currents alter the coil's inductive profile. The CON021 converter translates these impedance shifts into a standardized nominal sensitivity of 4 V/mm, ensuring precise conversion of high-frequency dynamic vibrations into voltage telemetry before packet packaging.
• Gap Voltage Validation and Hazardous Area Isolation The system establishes a predictable static voltage output linked to probe proximity, targeting a clean -10 VDC baseline for mechanical alignment checks within the standard -4 V to -20 V DC operational output range. Built-in explosion protection measures satisfying ATEX, IEC-Ex, and CSA boundaries isolate energy transmission to the sensor head, ensuring safety in volatile atmospheres without degrading the 15 us signal response time.
