EPRO PR6423/000-000 Standard Eddy Current Vibration Probe

The EPRO PR6423/000-000 is a classic standard fixed-type eddy current probe in the PR6423 sensor series, serving as the most widely used basic model for conventional turbomachinery condition monitoring. Adopting rigid integrated structure and standard factory calibration parameters, this sensor focuses on stable long-term non-contact measurement, perfectly matching CON series preamplifiers and MMS6000 TSI system modules. It is universally deployed for routine shaft vibration, radial displacement and shaft eccentricity monitoring on turbines, compressors and blowers, featuring high stability, strong versatility and low failure rate for general industrial working conditions.

1. Standard Structural Design & Installation Features

PR6423/000-000 adopts one-piece stainless steel rigid probe body with professional anti-corrosion and oil-resistant surface treatment, adapting to long-term stable operation in conventional bearing box oil mist and indoor industrial environments. Equipped with standard fixed rigid cable structure, it avoids bending fatigue damage and is suitable for fixed installation positions without frequent equipment vibration displacement or complex wiring bending.

With industry-standard 8mm probe head diameter and universal thread specification, the sensor supports unified installation gap setting and seamless plug-and-play replacement. It requires no special on-site modification or parameter adjustment during equipment overhaul and system renovation, featuring excellent compatibility and interchangeability for standard monitoring loops.

2. Standard Measurement & Electrical Performance

This standard probe inherits the classic high-precision parameters of the PR6423 series, with a complete 2mm linear measurement range and fixed 8V/mm sensitivity. Factory calibrated with standard 4140 steel materials, the full-scale linear error is strictly controlled within ±1% FS, accurately capturing conventional micro-amplitude vibration and tiny shaft floating of high-speed rotating machinery.

It supports a wide frequency response range of DC-20kHz, fully covering low-speed turning, variable-speed operation and rated high-speed working conditions of rotating equipment. The working temperature range of -35℃ to +180℃ ensures stable measurement output under normal industrial temperature changes, with extremely low zero drift and excellent long-term operational repeatability, reducing regular calibration and maintenance workload.

3. Rigid Cable Transmission & Anti-interference Ability

Matched with standard fixed rigid cable, PR6423/000-000 adopts high-purity oxygen-free copper core and high-temperature PTFE insulating layer, with outstanding aging resistance and chemical corrosion resistance. The integrated cable structure eliminates loose internal wiring, ensuring stable and consistent signal transmission for long-term fixed-point monitoring.

Built-in double-layer shielding structure effectively isolates conventional industrial electromagnetic interference, power frequency crosstalk and ground loop voltage drift. After precise factory impedance matching, it achieves distortion-free and lossless transmission of high-frequency eddy current signals, completely adapting to conventional short and medium-distance wiring scenarios of industrial monitoring loops.

4. Preamplifier & System Matching Solution

PR6423/000-000 forms a complete stable monitoring loop by cooperating with EPRO original CON series preamplifiers, fully compatible with all MMS6000 TSI system modules for universal industrial monitoring configuration:

• CON021: Standard cabinet-mounted preamplifier, the mainstream matching solution for conventional indoor monitoring loops, outputting stable linear voltage signals for daily vibration and displacement data collection.

• CON011: IP67 waterproof and explosion-proof preamplifier, suitable for on-site field installation and conventional hazardous area monitoring scenarios.

• CON031: Terminal wiring preamplifier, applicable for unified wiring and batch replacement of old MMS6000 system standard loops.
