Key Features

  • Matched probe + driver – PR6423 probe and CON021 converter are calibrated to work as a system, which typically shortens commissioning time.

  • Dual outputs – Dynamic AC signal for vibration analysis and a DC gap voltage for shaft position/thermal growth trending.

  • 10 m system length – The “-010” variant is commonly used where the monitor rack is further from the machine train.

  • Robust in harsh areas – Stainless probe construction and industry-proven CON021 driver for long-term stability near bearings and seals.

  • API 670 style scaling – Sensitivities align with common proximitor ranges, making it easy to integrate with standard racks and PLC cards expecting analog signals.

  • Flexible mounting – The “/003” thread configuration suits typical brackets and machine-case adaptors used on turbines and compressors.

  • Broad metal target compatibility – Works on conductive shaft materials (e.g., steel) without contact or added target hardware.

Technical Specifications
Brand / Model EPRO PR6423/003-010-CN + CON021
HS Code 903180 (Measuring or checking instruments, other)
Measurement Principle Non-contact eddy current proximity measurement
Target Material Conductive metals (typically steel shafts)
System Length 10 m total (indicated by “-010”; probe + extension cable)
Power Requirements (CON021) 24 V DC nominal (typical), low power consumption
Signal Input/Output Types Input: PR6423 probe; Outputs: dynamic AC vibration voltage and DC gap voltage
Sensitivity / Scale Factory-set; common calibrations around 4 mV/μm or 7.87 mV/μm (varies by tip size and range)
Operating Temperature Probe: up to approx. 180°C typical; CON021 electronics: approx. 0…+70°C
Communication Interfaces Analog outputs; no digital bus. Terminal screw connections on CON021.
Installation Method Threaded probe mount in machine case; CON021 DIN-rail or panel mounting (variant-dependent)
Dimensions & Weight Defined by variant; “-010” denotes total cable length of 10 m (system). Weight varies with cable length.
Application Fields

From my experience, this set is used wherever you need reliable non-contact readings on rotating equipment:

  • Steam and gas turbines: radial vibration and shaft relative position at bearings

  • Compressors and expanders: dynamic vibration and slow-roll runout checks

  • Pumps and fans: imbalance/misalignment detection and thermal growth tracking

  • Gearboxes: relative shaft vibration for early fault detection

  • Power generation, oil & gas, petrochemical, pulp & paper, steel plants

A maintenance lead at a combined-cycle plant mentioned the PR6423 + CON021 held calibration through a hot restart and only needed a quick re-gapping after a seal steam leak—no probe replacement required. That kind of resilience is what people typically look for in base‑loaded units.

Advantages & Value

  • Reliable signal chain – Stable scaling over distance and temperature helps avoid nuisance alarms.

  • Compatibility – Works with EPRO monitoring systems and most API 670 racks expecting analog prox inputs.

  • Lower lifecycle cost – Rugged probe design and proven CON021 electronics mean fewer unplanned swaps.

  • Simplified commissioning – Predefined system length and sensitivity reduce on-skid adjustments.

  • Supportable in the field – Standard cabling and hardware make spares planning more predictable.

Installation & Maintenance

  • Environment – Mount the probe through a rigid bracket or case adapter; keep cable runs away from VFD power cables when possible. Provide ventilation for the CON021 in the cabinet.

  • Gap setting – Set the probe mid-range to the specified gap (many setups land near ~1.0 mm, depending on calibration). Verify DC gap voltage within target.

  • Wiring – Maintain shield continuity, single-point grounding, and minimum bend radius on the extension cable. Tighten terminals on the CON021 and strain-relief the cable.

  • Safety – De-energize the cabinet before termination work. Confirm the machine is at a safe condition for any probe insertion/removal.

  • Routine care – Periodically clean the probe tip, re-check gap after outages, and verify sensitivity with a calibrated micrometer rig. Firmware updates are not applicable to the probe/CON021, but keep your monitoring rack firmware current.

Quality & Certifications

  • CE compliance (EMC) and RoHS

  • Manufactured under ISO 9001 quality system

  • Warranty: 365 days from delivery

You might notice that different sub-variants of PR6423 and CON021 have unique calibrations and thread forms. If you share your existing system length and monitor scaling, I can check compatibility and suggest the closest drop-in configuration to minimize rework.
