Product Overview

The Emerson CON021 + PR6423/01H-030 assembly provides a complete, high-precision solution for non-contact machinery monitoring. This modular system pairs the PR6423/01H-030 8mm eddy current probe with the CON021 signal conditioning driver to translate physical shaft displacement into accurate electronic signals. Engineered for the AMS Machinery Protection series, this combination tracks shaft vibration, axial position, and eccentricity in high-speed turbines, compressors, and pumps. We supply this entire assembly as 100% Brand New original equipment to ensure your mission-critical assets remain protected by authentic Emerson technology.

Technical Specifications

Engineering Advantages

• Pre-Matched Impedance: The CON021 driver matches the electrical impedance of the 3.0m PR6423 probe cable. This factory-aligned pairing eliminates the need for manual field calibration, ensuring the output voltage accurately represents the physical gap immediately upon installation.

• Superior Signal Conditioning: The CON021 driver filters out electronic background noise and amplifies the micro-vibrations detected by the probe. This ensures that your monitoring system receives a "clean" signal, which is critical for identifying early-stage bearing wear or shaft misalignment.

• High-Temperature Durability: The PR6423 probe survives continuous operation in temperatures up to +180°C. This allows for direct installation inside the turbine or gearbox housing where heat levels typically degrade standard proximity sensors.

• Non-Contact Precision: By utilizing eddy current technology, the sensor monitors the shaft without physical touch. This eliminates mechanical wear and ensures the system provides reliable data for years without requiring recalibration or component replacement.

FAQs

• Can I use the PR6423/01H-030 without the CON021 driver?

  No. The PR6423 probe is a passive sensor that requires the CON021 driver to provide the excitation frequency and condition the return signal. Using the probe without its matched driver will result in no signal output.

• How do I set the initial gap for this 8mm probe?

  Technicians typically use a multimeter to measure the DC output voltage from the CON021. For a standard 2.0 mm range, you generally aim for a "middle" voltage (often -10V DC) that corresponds to a gap of approximately 1.0 mm to 1.25 mm from the shaft surface.

• Is the 3.0m cable length fixed?

  The system is calibrated for exactly 3.0 meters of integral cable. You should not cut or shorten this cable, as doing so will change the system impedance and invalidate the calibration. If your installation requires more distance, use a certified Emerson extension cable designed for the AMS series.
