Features:

  • Wide frequency response from DC to 20,000 Hz with <15 μs rise time captures both static shaft position and high-frequency vibration transients on turbines, compressors, and fans.
  • Multiple hazardous area approvals including ATEX Ex ia IIC T4, IECEx, and CSA Class I Division 1/2 enable deployment in explosive environments across North America, Europe, and international markets.
  • Robust environmental design with -30 to 100°C operating range, 5g vibration resistance, and IP20 protection ensures reliable performance in demanding industrial conditions.
The PR6423/010-100-CN CON021 delivers a frequency range from DC to 20,000 Hz with a rise time under 15 microseconds—performance that captures fleeting vibration events often missed by slower converters. In high-speed turbomachinery, where shaft speeds can exceed 10,000 RPM, this rapid response means that transient rubs, sudden imbalances, or momentary instabilities are recorded before they escalate.

The PR6423/010-100-CN CON021 carries intrinsic safety approvals for Zone 0, 1, and Division 1 locations—ATEX II 2 G Ex ia IIC T4 Gb, IECEx Ex ia IIC T4 Gb, and CSA Class I Division 1—when used with safety barriers. For less stringent environments, non-sparking (nA) approvals cover Zone 2 and Division 2 applications.

The PR6423/010-100-CN CON021 is built for field reliability with an LMgSi 0.5 F22 aluminum housing that weighs just 120 grams yet withstands 5g vibration at 60 Hz. Installation requires no specialized tools: the probe connects via a self-locking Lemo plug, supply and output wires terminate in screw terminals accepting up to 1.5 mm² conductors, and the unit mounts with four included M5 screws.

The PR6423/010-100-CN CON021 Emerson Epro Eddy Current Signal Converter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Power Industry: Large steam turbines, gas turbines, and hydroelectric generator sets.
  • Petroleum and Chemical Industry: Large centrifugal/axial flow compressors, multistage pumps, and gearboxes.
  • Metallurgy and Mining: Large fans, blowers, and monitoring of key rotating bearings.
  • High-Precision Measurement: Features excellent linear response with a standard sensitivity of 4 V/mm (for a 4mm range), capturing even the slightest signs of mechanical wear.
  • Superior Frequency Response: Supports a bandwidth from 0 Hz (static displacement) to up to 10,000 Hz (dynamic vibration), ensuring no high-frequency mechanical faults are missed.
  • Reduced Downtime: Real-time data monitoring enables Condition-Based Maintenance (CBM), providing early warning before substantial equipment damage occurs, significantly improving factory operating efficiency.
  • Axial Displacement Monitoring (Thrust Measurement): Installed near the thrust bearing, it monitors the axial position of the rotor relative to the stator, preventing collisions between the rotor and stationary components due to excessive load.
  • Radial Vibration Monitoring (Radial Vibration): A pair of probes (X-Y monitoring) are mounted vertically at 90 degrees on the bearing housing to plot the shaft trajectory, diagnosing imbalance, misalignment, or bearing wear.
  • Speed ​​and Keyway Monitoring (Tacho/Phase): Monitors the keyways or protrusions on the shaft, providing speed signals and serving as a phase reference for vibration analysis.
Description
The PR6423/010-100-CN CON021 converts signals from eddy current probes into precise voltage outputs proportional to shaft displacement, velocity, and position. With a frequency response extending from DC to 20 kHz and rise time under 15 microseconds, it captures both static gaps and high-frequency vibration events on turbines, compressors, and fans. 

Designed for harsh industrial environments, the PR6423/010-100-CN CON021 operates reliably from -30 to 100°C and withstands 5g vibration at 60 Hz. Its IP20-rated housing weighs just 120 grams and mounts with four M5 screws. 

The PR6423/010-100-CN CON021 carries multiple hazardous area certifications. For intrinsic safety, it meets ATEX II 2 G Ex ia IIC T4 Gb, IECEx Ex ia IIC T4 Gb, and CSA Class I Division 1 requirements when used with safety barriers. For non-sparking applications, CSA Class I Division 2 approvals cover Zone 2 environments. 

This converter solves the challenge of obtaining reliable, high-bandwidth shaft monitoring data in explosive environments. The PR6423/010-100-CN CON021 pairs with PR6422 through PR6426 probes, with extended range versions available for PR6425 applications.
