Product Introduction
The PR6423/005-010 + CON021 is an elite-tier eddy current measurement system designed for critical asset protection. This kit features the 005-series sensor, which offers the highest level of manufacturing precision and thermal compensation within the EPRO portfolio. Paired with the CON021 converter, it provides a versatile dual-output signal (voltage and current), making it ideal for simultaneous use with high-speed vibration analyzers and standard DCS process control loops.
With a 1.0 m integrated cable, this PR6423/005-010 + CON021 configuration is specifically intended for installations where the signal converter or a junction box is mounted in the immediate vicinity of the sensor port. This “short-lead” design is highly effective at reducing signal noise in high-EMI environments. It is a preferred solution for monitoring shaft vibration, axial thrust, and eccentricity on large-scale steam turbines and high-speed compressors.
Frequently Asked Questions
Q: What is the benefit of the “005” series over the “003” or “002”? A: Honestly, the 005-series is the “gold standard” for stability. While all PR6423 sensors are good, the 005 is manufactured with tighter tolerances for linearity and temperature drift. If you are monitoring a turbine where a 10-micron error could cause a false trip, the 005-series provides that extra margin of certainty.
Q: Can I use a 4.0 m extension cable with this 1.0 m sensor? A: Yes, provided the total length matches the CON021 calibration. Most CON021 units are set for a 5.0 m total system length. By adding a 4.0 m extension to this 1.0 m sensor, you create a perfectly matched 5.0 m chain. Always verify the “System Length” etched on the converter nameplate.
Q: Does the CON021 require a special mounting orientation? A: No, but the most common mistake is mounting it in a high-heat area. The sensor can handle 180°C, but the CON021 converter is rated only to 85°C. In our experience, mounting the converter inside a ventilated junction box away from the turbine casing is the best way to prevent premature electronic failure.
