EPRO PR6423/002-030 + CON021 Standard 2m Rigid Eddy Current Sensor Set

The EPRO PR6423/002-030 paired with CON021 preamplifier forms a standard universal eddy current monitoring assembly, adopting 2-meter factory-matched rigid cable design for conventional industrial wiring scenarios. As a mainstream general-purpose set in the PR6423 series, it balances stable measurement performance, cost-effectiveness and field interchangeability, perfectly adapting to daily vibration and displacement monitoring of most standard rotating machinery. Fully compatible with MMS6000 TSI system modules, the factory-calibrated complete set requires no secondary debugging on site, serving as the preferred standard configuration for turbine, compressor and blower condition monitoring in power and petrochemical industries.

1. PR6423/002-030 Probe Structural & Measuring Advantages

PR6423/002-030 features an integrated one-piece stainless steel rigid probe body with professional oil-resistant, anti-corrosion and high-temperature passivation treatment. It stably adapts to long-term operation in conventional bearing box oil mist, indoor workshops and general industrial harsh environments, resisting daily mechanical vibration and dust erosion without performance attenuation.

Equipped with industry-standard 8mm probe head and universal M10×1 thread mounting specification, it supports full plug-and-play interchangeability with all conventional PR6423 series probes. The customized 2m fixed rigid cable is designed for standard short and medium-distance cabinet wiring, avoiding cable bending fatigue and signal instability caused by flexible cables in fixed installation scenarios. It needs no on-site structural modification or parameter recalibration during equipment replacement and system renovation, with excellent field adaptability.

2. Standard Precision Electrical & Measuring Performance

This standard probe inherits the classic series parameters, with a 2mm effective linear measurement range and fixed 8V/mm standard sensitivity. Factory calibrated with standard 4140 steel materials, the full-scale linear error is strictly controlled within ±1% FS, accurately capturing conventional micro-amplitude shaft vibration and tiny radial displacement changes of high-speed rotating equipment, providing reliable raw data for equipment health monitoring and fault early warning.

It supports a DC-20kHz wide frequency response range, fully covering full working conditions from equipment low-speed turning, variable-speed operation to rated high-speed rotation. With a stable operating temperature range of -40℃ to +125℃ and ultra-low temperature drift, it maintains consistent measuring accuracy under normal industrial temperature fluctuations, effectively reducing routine calibration and daily maintenance workload.

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

The matched 2-meter standard rigid cable adopts high-purity oxygen-free copper core and high-temperature PTFE insulation layer, featuring excellent anti-aging, oil-resistant and chemical corrosion resistance. The fixed rigid cable structure ensures stable wiring positioning for long-term fixed-point monitoring, eliminating wire twisting and fatigue damage risks of flexible cables in static installation environments.

Built-in double-layer shielding structure of tinned copper braid and aluminum foil full coverage effectively isolates on-site power frequency interference, electromagnetic crosstalk and ground loop drift. After professional factory impedance matching with CON021 preamplifier, it realizes zero-attenuation and distortion-free transmission of high-frequency eddy current signals, ensuring stable and jitter-free data output for standard monitoring loops.

4. CON021 Preamplifier Matching & Signal Processing Features

Matched exclusively with PR6423/002-030 probe, the CON021 cabinet-mounted preamplifier is the standard signal processing unit for this universal monitoring set. With IP20 protection grade and standard DIN rail installation structure, it is suitable for indoor centralized control cabinet deployment, completing real-time eddy current signal excitation, waveform demodulation and linear voltage conversion.

It outputs standard stable linear voltage signals that fully match the input specifications of MMS6000 TSI system modules. Built-in reverse connection, short-circuit and overload multiple protection circuits prevent circuit damage and signal abnormality caused by on-site wiring errors. With fast dynamic response speed and full-band signal restoration capability, it ensures real-time and synchronous monitoring of rotating machinery operating status.
