EPRO PR6423/016-030 + CON021 6m Rigid High-Temp Eddy Current Sensor Set

The EPRO PR6423/016-030 paired with original CON021 preamplifier forms a factory-calibrated 6-meter long-distance high-temperature resistant eddy current monitoring assembly. Featuring exclusive 030 upgraded high-temperature protection specification and standard rigid cable structure, this complete set is purpose-built for large-span equipment-cabinet wiring and continuous high-heat industrial operating environments. Different from short and medium-length conventional probes, the 6m cable specification perfectly covers dispersed field equipment layout demands without redundant wiring chaos. Matched with dedicated cabinet-type signal processing unit, it delivers consistent low-drift measurement performance, fully compatible with MMS6000 TSI system modules. Widely deployed in thermal power, petrochemical and heavy industrial fields for long-term stable shaft vibration and radial displacement monitoring of large rotating machinery.

1. PR6423/016-030 Probe Structural & Protective Advantages

PR6423/016-030 adopts integrated one-piece stainless steel probe body with upgraded high-temperature oil-resistant and anti-aging passivation treatment. Adopting premium 030 high-temperature enhanced specification, the probe maintains stable structural rigidity and measurement accuracy under prolonged heat radiation and bearing box oil mist erosion, outperforming standard low-grade probes in thermal stability and service life. The industrial reinforced structure resists continuous operating vibration and mechanical impact, avoiding zero drift and structural loosening in long-cycle industrial operation.

Equipped with industry-standard 8mm probe head and universal M10×1 thread mounting dimension, it achieves full plug-and-play interchangeability with all PR6423 series probes. The customized 6m full-length rigid cable fills the specification gap between 4m medium-long probes and 10m ultra-long probes, perfectly adapting to large-span fixed wiring scenarios of dispersed industrial equipment. The rigid cable structure eliminates bending fatigue, sagging deformation and signal instability risks of flexible cables, realizing neat layout and maintenance-free fixed-point installation.

2. Calibrated Measurement & Electrical Performance

This high-temperature long-cable probe retains series-standard 2mm effective linear measurement range and 8V/mm fixed sensitivity, strictly factory-calibrated with standard 4140 ferromagnetic steel. The full-scale linear error is controlled within ±1% FS, enabling precise capture of micro shaft vibration, radial runout and floating displacement of high-speed rotating units, providing accurate and reliable raw data for equipment condition trend analysis and early fault diagnosis.

It supports DC-20kHz full-band frequency response, covering the full operating range of rotating machinery from low-speed turning and variable-speed regulation to full-load high-speed operation. Benefiting from 030 upgraded thermal resistance, the probe features an ultra-wide working temperature range of -40℃ to +180℃, with ultra-low temperature drift under drastic ambient temperature fluctuations. It effectively reduces routine field calibration frequency, fully adapting to 24/7 uninterrupted monitoring of high-heat industrial equipment.

3. 6m Rigid Cable Transmission & Anti-interference Capability

Matched with professional 6-meter long-distance rigid cable, the sensor adopts high-purity oxygen-free copper core and high-temperature resistant PTFE composite insulation layer, with excellent anti-aging, oil corrosion and thermal radiation resistance. The integral rigid forming process ensures stable geometric cable positioning after long-term static laying, completely avoiding signal jitter and attenuation caused by flexible cable deformation and fatigue aging in long-distance wiring.

Built-in double-layer shielding structure of aluminum foil full coverage and tinned copper braid effectively suppresses on-site high-power equipment electromagnetic coupling interference, power frequency noise and ground loop potential difference. The whole set undergoes exclusive long-line impedance matching calibration before delivery, ensuring low-loss and distortion-free transmission of high-frequency eddy current signals over 6m long distance, solving the common long-line signal waveform distortion problem of ordinary probe sets.

4. CON021 Preamplifier Matching & Customized Processing Features

The supporting CON021 DIN-rail preamplifier is factory optimized and calibrated for 6m long-cable high-temperature probes, forming a dedicated long-span high-stability monitoring loop with PR6423/016-030. Differentiated from general preamplifier matching, this complete set completes targeted signal compensation for long-line transmission loss and high-temperature signal drift, ensuring consistent signal output accuracy under complex working conditions.

• Long-line Signal Compensation: Built-in customized algorithm compensates 6m cable transmission attenuation, restoring high-fidelity original vibration signal and avoiding data distortion caused by long-distance transmission.

• High-temperature Adaptation Optimization: Matches the 030 high-temperature probe’s thermal drift characteristics, realizing dynamic temperature correction and maintaining stable linear output in fluctuating high-temperature environments.

• Cabinet Centralized Deployment: Standard DIN-rail mounting structure fits indoor centralized control cabinet layout, supporting unified signal acquisition and system access for multiple long-distance monitoring points, with stable anti-interference performance for indoor complex electromagnetic environments.
