EPRO PR6423/013-130 3m Armored High-protection Eddy Current Vibration Probe

The EPRO PR6423/013-130 is a high-reliability armored eddy current probe upgraded from the standard PR6423 series, equipped with 3-meter customized armored cable and exclusive 130 enhanced mechanical protection specification. Differing from the basic 020 ordinary probes, this model features full metal armored reinforcement and terminal wiring optimization, perfectly solving cable extrusion, friction damage and signal instability in medium-distance harsh industrial wiring scenarios. Retaining series-standard high-precision non-contact measurement performance, it is fully compatible with CON series preamplifiers and MMS6000 TSI system modules. It is widely deployed for shaft vibration, radial displacement and eccentricity monitoring of medium-span rotating machinery in power, petrochemical and mechanically harsh industrial sites.

1. Armored Structural Design & Installation Advantages

PR6423/013-130 adopts integrated high-strength stainless steel probe body with upgraded oil-resistant, high-temperature anti-corrosion and wear-resistant passivation treatment. The 130-level enhanced protective structure adds a full outer metal armored layer, effectively resisting external extrusion, sharp friction, tensile force and mechanical impact that ordinary rigid probes cannot withstand, adapting to long-term operation in heavy-dust, oil-mist and vibration-intensive bearing box environments.

It inherits the industry-standard 8mm probe head diameter and universal M10×1 thread mounting specification, realizing complete plug-and-play interchangeability with all conventional PR6423 series probes. Matched with exclusive 3m medium-distance armored cable, it perfectly covers standard medium-span equipment-to-cabinet wiring demands, avoiding the length limitation of short cables and redundant layout of ultra-long cables. Optimized for terminal wiring configuration, it requires no on-site structural modification or parameter recalibration during equipment replacement and system renovation, delivering excellent field adaptability and maintenance convenience.

2. Core Measurement & Electrical Performance

This high-protection armored probe maintains the classic series high-precision measurement 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 a wide operating temperature range of -40℃ to +180℃ and ultra-low temperature drift, it maintains consistent measurement accuracy under severe industrial temperature fluctuations, effectively reducing routine calibration frequency and daily maintenance workload for 24/7 long-term unattended monitoring.

3. 3m Armored Cable Transmission & Anti-interference Ability

Matched with customized 3-meter high-grade armored cable, the probe adopts high-purity oxygen-free copper core and high-temperature PTFE insulation layer, featuring excellent anti-aging, oil corrosion resistance and high-temperature radiation resistance. The outer seamless metal armored layer provides all-round mechanical protection, completely eliminating cable breakage, extrusion deformation and aging damage risks in frequently maintained and mechanically complex medium-distance wiring paths.

Built-in double-layer shielding structure of tinned copper braid and full-coverage aluminum foil effectively isolates on-site power frequency interference, electromagnetic crosstalk 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. The optimized 3m medium-distance length balances signal loss control and wiring flexibility, ensuring ultra-stable and jitter-free data output for harsh-condition monitoring loops.

4. Preamplifier & System Matching Solution

PR6423/013-130 features dedicated terminal wiring adaptation, forming a high-protection industrial monitoring loop with original EPRO CON series preamplifiers, fully compatible with all MMS6000 TSI system modules, ideal for standardized medium-distance harsh environment projects:
