EPRO CON021+PR6423/10R-010-CN Current Sensor System

The Epro CON021+PR6423/10R-010-CNt, also cataloged as the PR6423 Eddy Current Proximity 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. It maps physical micro-displacements into linear voltage variations natively at the hardware tier to drive real-time machinery safety loops.

Hardware Specifications

Mechanical Monitoring & TSI Features

• Eddy-Current Probe Scaling and Scale Factor Calibration The PR6423 sensor radiates a high-frequency electromagnetic field from its tip into the targeted electrically conducting steel cylindrical shaft. As mechanical gap distances fluctuate, eddy currents alter the coil's inductive profile. The CON021 converter translates these impedance shifts into a standardized Incremental Scale Factor (ISF) of 8 V/mm, ensuring precise conversion of high-frequency dynamic vibrations into voltage telemetry before packet packaging.
• Gap Voltage Validation and Thermal Compensation The system establishes a predictable static voltage output linked to probe proximity, targeting a clean -10 VDC baseline for mechanical alignment checks. Internal hardware compensation networks mitigate baseline wander across the wide -35 to +180 deg C sensor temperature window, constraining zero-point thermal deviation to 200 mV per 100 K to maintain calibration validity under intense ambient thermal loads.

Frequently Asked Questions

Q: What specific hardware or signal parameters manifest if the total extension cabling array exceeds the factory 1 m + 29 m length boundaries?

A: Altering the combined electrical length of the sensor network changes the total loop capacitance and impedance profile. The CON021 converter will experience a severe shift in its calibrated 8 V/mm sensitivity curve, introducing measuring errors that exceed the +/- 1% linearity specification and causing potential tracking anomalies at the main monitor rack.

Q: Can the blunt-cut ends of the transducer extension cable be terminated inside standard high-vibration terminal boxes without ferrules?

A: No, wire termination guidelines require crimped ferrules on all blunt-cut stranded wire ends before inserting them into screw terminal blocks. Raw stranded wire connections under 5 g, 60 Hz vibration profiles will experience contact loosening and fretting corrosion, causing loop resistance spikes that the converter reads as an unmasked sensor fault.
