Description

The PR 6423/010-010 is a high-precision, non-contact eddy current measurement system consisting of a sensor and the CON021 signal converter. This assembly is engineered for critical turbomachinery protection, providing accurate monitoring of shaft vibration, axial thrust position, and eccentricity. By converting high-frequency electromagnetic oscillations into standardized voltage signals, the system enables real-time assessment of mechanical health in steam turbines, gas turbines, and large centrifugal compressors. It is a vital component for detecting bearing wear and shaft misalignment, helping to prevent catastrophic equipment failure and minimize unscheduled downtime in power generation and petrochemical facilities.

Features

Eddy Current Principle: Utilizes high-frequency electromagnetic fields for non-contact distance measurement.
Signal Processing: The CON021 converter provides linearized, temperature-compensated voltage outputs.
Signal Integrity: Designed for long-distance transmission with high signal-to-noise ratios in industrial environments.
Robust Design: Converter features a DIN-rail mountable housing with galvanic isolation to mitigate ground loop interference.
Calibration: Integrated adjustments allow for fine-tuning to specific shaft metallurgical properties.

Applications

Turbine supervisory instrumentation (TSI).
Shaft vibration monitoring for rotating machinery.
Axial position and thrust monitoring.
Eccentricity and rod drop measurements in reciprocating compressors.

Installation Guidelines

Mounting: The CON021 converter is designed for standard DIN-rail mounting within a control cabinet or junction box.
Wiring: Use shielded instrumentation cable for signal transmission to maintain immunity against EMI. Ensure proper grounding of the cable shield at the control room end only to avoid ground loops.
Sensor Handling: The sensor tip is delicate; avoid mechanical impact. Ensure the mounting bracket is rigid to prevent resonance-induced measurement errors.
Power: Verify the supply voltage is within the -18 V to -32 VDC range before applying power.
Safety: Always disconnect power before performing wiring modifications or removing the converter from the DIN rail.

FAQ

What is the primary function of the CON021 converter? The CON021 acts as the signal conditioner for the PR 6423 sensor, converting the raw high-frequency oscillation data into a linear DC voltage output that can be processed by PLC or DCS monitoring systems.

Can this system be used on non-ferrous shafts? The system is calibrated for standard ferromagnetic steel (e.g., 42CrMo4). Using it on different materials will affect the sensitivity and linearity; recalibration or specific material compensation is required.
