EPRO PR6423/001-010 Ultra-short Mini Eddy Current Vibration Probe

The EPRO PR6423/001-010 is a specialized ultra-short mini eddy current probe in the PR6423 sensor series, uniquely designed for ultra-narrow, confined and compact equipment installation spaces. Different from standard-length probes, this model features a shortened integrated probe body and miniature sensing structure, retaining standard series measurement precision while solving installation bottlenecks of closed bearing boxes and dense equipment layouts. Fully compatible with CON series preamplifiers and MMS6000 TSI system modules, it delivers high-stability non-contact micro-displacement and micro-vibration monitoring for small-scale high-speed rotating machinery and precision industrial equipment.

1. Mini Ultra-short Structural Design & Installation Advantages

PR6423/001-010 adopts one-piece high-strength stainless steel ultra-short probe body with professional anti-corrosion, oil-resistant and high-temperature passivation treatment, adapting to long-term stable operation in confined bearing box oil mist and sealed industrial cavities. The customized shortened overall structure eliminates length interference issues that plague standard probes, perfectly fitting ultra-narrow mounting gaps and compact equipment assembly spaces.

It inherits the universal 8mm probe head specification and standard thread mounting dimensions of the PR6423 series, ensuring complete plug-and-play interchangeability with conventional probes. No on-site structural modification, wiring adjustment or parameter recalibration is required during equipment maintenance and system renovation. With integrated anti-vibration mechanical design, it resists continuous equipment operating vibration without loosening or signal deviation, featuring excellent on-site adaptability.

2. Precision Measurement & Electrical Performance

Tailored for micro-precision monitoring scenarios, this sensor maintains the industry-standard 2mm effective linear measurement range and fixed 8V/mm high sensitivity, factory-calibrated with standard 4140 steel materials. The full-scale linear error is strictly controlled within ±1% FS, enabling accurate capture of ultra-micro vibration and subtle shaft floating changes that ordinary probes struggle to identify, supporting high-precision equipment health diagnosis and early fault warning.

Equipped with a DC-20kHz ultra-wide frequency response range, it fully covers low-speed jogging, variable-speed regulation and rated high-speed operating conditions of precision rotating equipment. It features stable wide-temperature performance from -40℃ to +125℃, with ultra-low temperature drift and zero-shift output, maintaining consistent measurement accuracy in complex temperature-variable industrial environments and reducing routine calibration and maintenance workload.

3. Standard Cable Transmission & Anti-interference Performance

Matched with standardized short-distance rigid cable, PR6423/001-010 adopts high-purity oxygen-free copper core and high-temperature PTFE insulation layer, with excellent anti-aging, oil-resistant and chemical corrosion resistance. The short cable structure minimizes line loss and signal attenuation, ensuring original and authentic collection of micro-vibration signals.

Built-in double-layer shielding structure composed 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, it realizes distortion-free and lossless signal transmission, ensuring ultra-stable data output for precision monitoring loops in complex electromagnetic environments.

4. Preamplifier & System Matching Solution

PR6423/001-010 forms a complete high-precision monitoring loop with EPRO original CON series preamplifiers, fully compatible with all MMS6000 TSI system modules, adapting to precision monitoring system configuration requirements:
