EPRO PR6423/011-131 1m Armored Short Cable Eddy Current Vibration Probe

The EPRO PR6423/011-131 is a specialized short armored eddy current probe in the PR6423 series, tailored for ultra-narrow confined installation spaces and mechanical damage-prone industrial sites. Featuring customized 1-meter ultra-short armored cable and 131-level reinforced protective structure, it solves the wiring extrusion and cable damage risks of ordinary short probes in compact equipment cabins. Maintaining series-standard high-precision non-contact measurement performance, it perfectly matches CON series preamplifiers and MMS6000 TSI system modules. It is widely used for precise shaft vibration, radial displacement and eccentricity monitoring of compact high-speed rotating machinery in power, petrochemical and industrial precision monitoring scenarios.

1. Armored Structural Design & Installation Advantages

PR6423/011-131 adopts integrated high-strength stainless steel probe body with professional oil-resistant, anti-corrosion and high-temperature passivation treatment. The exclusive 131 enhanced armored structure adds outer metal mechanical protection layer, effectively resisting external extrusion, sharp friction and tensile damage that ordinary non-armored probes cannot withstand, adapting to long-term operation in confined bearing box oil mist and dense equipment layouts.

It retains industry-standard 8mm probe head diameter and universal M10×1 thread mounting specification, achieving full plug-and-play interchangeability with all conventional PR6423 series probes. The customized 1m ultra-short cable is specially designed for ultra-narrow installation gaps and short-distance terminal wiring scenarios, eliminating redundant cable stacking and wiring disorder. No on-site structural modification or parameter recalibration is required during equipment maintenance and system renovation, with excellent field adaptability.

2. Core Measurement & Electrical Performance

This short armored probe inherits 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 equipment, providing reliable precise data for equipment fault early warning and operation trend analysis.

It supports DC-20kHz ultra-wide frequency response range, fully covering low-speed jogging, variable-speed regulation and rated high-speed operating conditions of precision rotating machinery. With a wide operating temperature range of -40℃ to +180℃ and ultra-low temperature drift, it maintains stable measurement accuracy under complex industrial temperature fluctuations, effectively reducing routine calibration frequency and daily maintenance workload.

3. 1m Short Armored Cable & Anti-interference Performance

Matched with customized 1-meter ultra-short 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 metal armored layer provides all-round mechanical protection, completely avoiding cable breakage, extrusion deformation and aging damage in compact and frequently maintained equipment areas.

Built-in double-layer shielding structure of tinned copper braid and full-coverage aluminum foil effectively isolates on-site 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. The ultra-short cable design minimizes line signal loss, ensuring ultra-high fidelity data output for precision monitoring loops.

4. Preamplifier & System Matching Solution
