EPRO PR6423/012-100 2m Extended Rigid Eddy Current Vibration Probe

The EPRO PR6423/012-100 is a cost-effective extended rigid eddy current probe in the standard PR6423 sensor series, configured with 2-meter factory-matched rigid cable and optimized compact probe structure. Designed for general industrial medium-short distance fixed wiring scenarios, it balances stable structural durability and universal measurement precision, making up for the installation limitations of ultra-short probes while avoiding redundant cable length of long-specification models. Fully compatible with CON series preamplifiers and MMS6000 TSI system modules, it provides reliable non-contact monitoring of shaft vibration, radial displacement and shaft eccentricity for conventional turbomachinery and rotating equipment in power, petrochemical and general industrial fields.

1. Structural Design & Installation Advantages

PR6423/012-100 adopts integrated one-piece stainless steel probe body with professional oil-resistant, anti-corrosion and high-temperature passivation treatment. The compact streamlined probe structure adapts to most conventional bearing box installation environments, resisting long-term erosion of oil mist, industrial dust and humid air, and maintaining stable structural performance under continuous equipment operating vibration.

It features industry-standard 8mm probe head diameter and universal M10×1 thread mounting specification, achieving complete plug-and-play interchangeability with all conventional PR6423 series probes. Equipped with standardized 2m extended rigid cable, it perfectly suits medium-short distance fixed wiring demands, solving the installation and wiring difficulties of ultra-short probes in slightly spaced equipment-cabinet layouts. No on-site structural modification or parameter recalibration is required during equipment replacement and system renovation, with excellent field versatility and compatibility.

2. Core Measurement & Electrical Performance

This extended rigid 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 machinery, providing stable and accurate 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 complex industrial temperature fluctuations, effectively reducing routine calibration frequency and daily maintenance workload for long-term unattended monitoring.

3. 2m Rigid Cable Transmission & Anti-interference Ability

Matched with standardized 2-meter rigid 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 fixed rigid cable structure eliminates bending fatigue, twisting deformation and signal attenuation risks of flexible cables in long-term fixed installation scenarios, ensuring stable wiring positioning and durable operation.

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, ensuring jitter-free and high-fidelity data output for conventional industrial monitoring loops.

4. Preamplifier & System Matching Solution

PR6423/012-100 forms a complete stable industrial monitoring loop with original EPRO CON series preamplifiers, fully compatible with all MMS6000 TSI system modules, suitable for standardized medium-short distance monitoring system configuration:

• CON021: Standard DIN-rail cabinet preamplifier, the mainstream matching solution for indoor centralized monitoring loops, providing stable signal demodulation and linear voltage output.

• CON011: IP67 waterproof and explosion-proof preamplifier, applicable to conventional field hazardous areas and outdoor equipment monitoring scenarios.

• CON031: Terminal wiring preamplifier, ideal for unified wiring renovation and batch replacement of old standardized monitoring systems.
