EPRO PR6423/014-010 4m Standard Rigid Short-thread Eddy Current Vibration Probe

The EPRO PR6423/014-010 is a cost-effective short-thread rigid eddy current probe in the PR6423 series, configured with factory-calibrated 4-meter standard rigid cable and exclusive 010 short-thread specification. Optimized for medium-long distance fixed wiring and compact threaded installation scenarios, it fills the gap between 3m medium-length probes and ultra-long 10m probes. Featuring compact thread structure, stable universal measurement performance and excellent cost performance, it is fully compatible with CON series preamplifiers and MMS6000 TSI system modules. Widely applied in power, petrochemical and general industrial fields, it provides reliable non-contact shaft vibration, radial displacement and eccentricity monitoring for medium and large rotating machinery with limited threaded mounting space.

1. Short-thread Structural Design & Installation Advantages

PR6423/014-010 adopts integrated one-piece high-strength stainless steel probe body with professional oil-resistant, anti-corrosion and high-temperature passivation treatment. Different from standard long-thread probes, the 010 upgraded short-thread structure is tailored for equipment with shallow threaded holes and compact mounting bases, effectively solving installation interference problems of conventional long-thread probes in confined threaded spaces.

It retains industry-standard 8mm probe head diameter and universal M10 thread mounting standard, realizing complete plug-and-play interchangeability with all conventional PR6423 series probes. Equipped with customized 4m medium-long rigid cable, it perfectly adapts to medium-long distance fixed wiring between field equipment and control cabinets, avoiding length insufficiency of 3m probes and redundant cable layout of ultra-long models. No on-site structural modification or parameter recalibration is required during equipment replacement and system renovation, delivering outstanding field adaptability and maintenance simplicity.

2. Core Measurement & Electrical Performance

This short-thread rigid probe inherits the series mature 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 24/7 long-term unattended monitoring.

3. 4m Rigid Cable Transmission & Anti-interference Ability

Matched with customized 4-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 high-temperature radiation resistance. The fixed rigid cable structure eliminates bending fatigue, twisting deformation and signal attenuation risks of flexible cables during long-term static fixed installation, ensuring stable wiring positioning and long-term durable operation for medium-long distance monitoring points.

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 medium-long distance industrial monitoring loops.

4. Preamplifier & System Matching Solution

PR6423/014-010 forms a complete stable medium-long distance monitoring loop with original EPRO CON series preamplifiers, fully compatible with all MMS6000 TSI system modules, suitable for standardized medium-long distance industrial monitoring projects:

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

• CON011: IP67 waterproof and explosion-proof preamplifier, applicable to field medium-long distance wiring and conventional hazardous area monitoring scenarios.

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

5. Core Product Selling Points & Industrial Values

• 010 Exclusive Short-thread Design: Optimized short thread structure solves installation limitations of long-thread probes for shallow hole and compact base equipment, expanding applicable installation scenarios.

• 4m Medium-long Rigid Cable: Classic 4-meter cable length perfectly covers medium-long distance wiring demands, balancing layout neatness and transmission stability without cable redundancy.

• Universal Stable Precision Performance: Mature factory calibration and series-standard parameters ensure low linear error and high repeatability, meeting daily high-precision monitoring demands of mainstream rotating machinery.

• Excellent Long-term Durability: Oil-proof, dust-proof, high-temperature resistant and anti-vibration design supports 24/7 uninterrupted operation in general harsh industrial environments.

• Plug-and-play Compatibility: Standard probe head and electrical parameters support seamless replacement of conventional PR6423 probes, with low renovation cost and simple on-site debugging.
