EPRO PR6423/013-020 3m Standard Rigid Eddy Current Vibration Probe

The EPRO PR6423/013-020 is a cost-effective standard rigid eddy current probe in the PR6423 series, configured with factory-matched 3-meter rigid cable and classic 020 basic protection specification. Optimized for conventional medium-distance fixed wiring and general industrial working conditions, it delivers stable and reliable non-contact measurement performance with balanced cost and practicability. Fully compatible with CON series preamplifiers and MMS6000 TSI system modules, it is widely used for shaft vibration, radial displacement and eccentricity monitoring of medium and small-sized rotating machinery in power plants, petrochemical factories and general industrial workshops, serving as a mainstream universal monitoring sensor for standardized industrial projects.

1. Structural Design & Installation Advantages

PR6423/013-020 adopts integrated one-piece stainless steel probe body with professional oil-resistant, dust-proof and anti-corrosion passivation treatment. The classic industrial-grade structure adapts to long-term stable operation in conventional bearing box oil mist and indoor industrial environments, resisting continuous equipment vibration and daily environmental erosion without structural deformation or performance attenuation.

It retains industry-standard 8mm probe head diameter and universal M10×1 thread mounting specification, realizing full plug-and-play interchangeability with all conventional PR6423 series probes. Equipped with exclusive 3m standard rigid cable, it perfectly solves the medium-distance wiring demands between field equipment and control cabinets, making up for the length limitation of 2m short cables while avoiding redundant layout of ultra-long cables. No on-site structural modification or parameter recalibration is required during equipment replacement and system renovation, featuring excellent field versatility and installation adaptability.

2. Core Measurement & Electrical Performance

This standard rigid probe inherits the mature series 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 stable operating temperature range of -40℃ to +180℃ and ultra-low temperature drift, it maintains consistent measurement accuracy under conventional industrial temperature fluctuations, effectively reducing routine calibration frequency and daily maintenance workload for long-term unattended monitoring.

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

Matched with customized 3-meter standard 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 temperature radiation resistance. The fixed rigid cable structure eliminates bending fatigue, twisting deformation and signal attenuation risks existing in flexible cables during long-term static fixed installation, ensuring stable wiring positioning and long-term durable operation.

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

4. Preamplifier & System Matching Solution

PR6423/013-020 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-distance monitoring system configuration and batch project deployment:

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

• CON011: IP67 waterproof and explosion-proof preamplifier, applicable to conventional field working conditions and general hazardous area monitoring scenarios.

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