EPRO PR6423/10R-030 + CON021 Complete Eddy Current Sensor System

The EPRO PR6423/10R-030 paired with CON021 preamplifier forms a full-set industrial eddy current monitoring system, customized for ultra-long-distance field wiring and complex high-vibration working conditions. Different from conventional short-cable probe assemblies, this 10R version features a 10-meter anti-fatigue flexible cable, solving long-span wiring difficulties between field equipment and central control cabinets. Matched with the standard CON021 cabinet-mounted preamplifier, the whole set delivers stable signal excitation, precise demodulation and linear voltage output, perfectly adapting to MMS6000 TSI systems. It is widely used for shaft vibration, axial displacement and eccentricity monitoring of large turbines and compressors in power and petrochemical industries.

1. PR6423/10R-030 Probe Structural & Measuring Advantages

Built with integrated stainless steel probe body and high-standard anti-corrosion passivation treatment, PR6423/10R-030 resists oil mist erosion, dust accumulation and long-term mechanical vibration inside bearing boxes. Adopting universal 8mm probe head specification and standard thread installation structure, it supports direct replacement of all conventional PR6423 series probes without on-site modification or parameter recalibration, featuring excellent interchangeability.

This sensor adopts upgraded linear measurement design with a 3mm effective linear range, wider than ordinary 2mm probes, suitable for large-stroke shaft displacement and floating monitoring scenarios. It maintains ±1% FS high linearity accuracy, accurately capturing micro vibration and tiny shaft position changes of high-speed rotating equipment. With a wide temperature tolerance of -40℃ to +125℃ and ultra-low temperature drift, it ensures consistent measuring precision in extreme industrial temperature environments.

2. 10M Flexible Cable Material & Long-distance Transmission Performance

The core advantage of PR6423/10R-030 lies in its exclusive 10-meter high-elastic flexible cable, the longest flexible cable specification in the PR6423 series. The cable adopts fatigue-resistant oxygen-free copper core and high-temperature PTFE insulation layer, possessing outstanding anti-aging, oil-resistant and high-temperature radiation resistance. It supports frequent bending and twisting without internal wire breakage, fully adapting to long-term vibration of rotating equipment and complex curved wiring paths.

Equipped with professional double-layer shielding structure of tinned copper braid and aluminum foil full coverage, the cable effectively isolates on-site high-frequency electromagnetic interference, ground loop drift and signal crosstalk. Even in 10-meter ultra-long-distance transmission, it realizes zero attenuation and distortion-free transmission of high-frequency eddy current signals. Strict factory impedance matching ensures perfect signal adaptation with CON021 preamplifier, avoiding data jitter and monitoring deviation caused by long-line signal loss.

3. CON021 Preamplifier Matching & Signal Processing Features

Supporting one-to-one dedicated matching with PR6423/10R-030, the CON021 preamplifier is the standard core signal processing unit for this complete monitoring system. Installed inside indoor centralized control cabinets with IP20 protection grade, it completes eddy current signal excitation, waveform demodulation and analog voltage conversion in real time, outputting standard stable linear voltage signals that fully adapt to MMS6000 series TSI monitoring module input standards.

Built-in multiple protection mechanisms including reverse connection prevention, short-circuit protection and overload protection effectively avoid circuit damage and signal abnormality caused by on-site wiring errors. With a 0–20kHz ultra-wide frequency response range and fast dynamic response speed, it synchronously restores real-time vibration and displacement data of rotating shafts, ensuring no signal lag or waveform distortion during high-speed equipment operation.
