EPRO PR6423/010-100 10m Ultra-long Rigid Eddy Current Vibration Probe

The EPRO PR6423/010-100 is a premium ultra-long rigid eddy current probe in the PR6423 sensor series, uniquely configured with factory integrated 10-meter fixed rigid cable and industrial enhanced mechanical resistance. Differing from conventional medium and short-length probes, this model is purpose-built for ultra-long-distance fixed wiring scenarios where flexible cables are unnecessary and structural stability is critical. It retains standard series high-precision non-contact measurement performance, with upgraded shock and vibration resistance, perfectly compatible with CON series preamplifiers and MMS6000 TSI system modules. Widely deployed in large-scale thermal power, petrochemical and offshore energy industries, it provides continuous and reliable shaft vibration, radial displacement and eccentricity monitoring for large-span rotating machinery equipment.

1. Structural Design & Installation Advantages

PR6423/010-100 adopts an integrated full stainless steel probe body with professional high-temperature oil-resistant and anti-corrosion passivation treatment. Featuring industrial-grade enhanced mechanical structure, it withstands 20g peak-to-peak vibration and 50g impact load, far exceeding the mechanical resistance of standard probes, perfectly adapting to long-term high-vibration operation of heavy-duty rotating equipment without structural deformation or loose installation.

Equipped with industry-standard 8mm probe head and universal M10×1 thread mounting specification, it achieves complete plug-and-play interchangeability with all conventional PR6423 series probes. The exclusive 10-meter ultra-long rigid cable fills the gap of long-distance fixed wiring for standard probes, eliminating bending fatigue and signal instability risks of flexible cables in static installation. No on-site structural modification or parameter recalibration is required during equipment overhaul and system renovation, with excellent field adaptability and replaceability.

2. Core Measurement & Electrical Performance

This ultra-long probe inherits the classic series high-precision parameters, with a 2mm effective linear measurement range and fixed 8V/mm standard sensitivity. Factory calibrated with standard 4140 ferromagnetic steel, the full-scale linear error is strictly controlled within ±1% FS, accurately capturing micro-amplitude vibration and tiny shaft floating changes of high-speed rotating machinery, providing precise and reliable raw data for equipment fault early warning and operation trend analysis.

It supports a DC-20kHz ultra-wide frequency response range, fully covering low-speed jogging, variable-speed regulation and rated high-speed operating conditions of industrial rotating equipment. With an ultra-wide temperature adaptation range of -40℃ to +180℃ and short-term extreme resistance up to +200℃, it maintains ultra-low temperature drift and stable measurement accuracy under severe temperature fluctuations, greatly reducing routine calibration and daily maintenance workload.

3. 10m Ultra-long Rigid Cable Transmission & Anti-interference Ability

Matched with customized 10-meter premium rigid cable, the probe adopts high-purity oxygen-free copper core and upgraded high-temperature PTFE insulation layer, featuring excellent anti-aging, oil corrosion resistance and high-temperature radiation resistance. The reinforced rigid cable structure ensures stable fixed positioning for ultra-long-distance wiring, completely avoiding twisting deformation, wire fatigue and signal attenuation problems of flexible cables during long-term static operation.

Built-in double-layer shielding structure composed of tinned copper braid and full-coverage aluminum foil effectively isolates on-site strong electromagnetic crosstalk, power frequency interference and ground loop potential difference. After strict factory impedance matching with CON series preamplifiers, it realizes distortion-free and zero-attenuation transmission of high-frequency eddy current signals, solving the long-line signal loss problem of ordinary probes in ultra-long-distance monitoring loops and ensuring stable jitter-free data output.

4. Preamplifier & System Matching Solution
