Product Overview

The Emerson EPRO CON021 + PR6423/010-100 constitutes a high-precision eddy-current proximity transducer system. This assembly converts the physical distance between the probe tip and a rotating shaft into a proportional voltage signal. It monitors critical machinery parameters, including radial shaft vibration, axial position, and thermal expansion. We provide this system as 100% Brand New and Original, ensuring full compliance with API 670 standards for the protection of high-speed turbines, compressors, and pumps.

Technical Specifications

Engineering Advantages

• Precision Voltage Conversion: The CON021 driver utilizes advanced oscillation circuitry to translate the probe's impedance changes into a highly accurate voltage output. This ensures that your monitoring system receives clean, linear data for both static position and dynamic vibration analysis.

• Extreme Environment Durability: The PR6423 probe head withstands temperatures up to +180 °C. This thermal resistance allows for direct installation inside turbine housings or near hot bearings where standard sensors typically fail.

• API 670 Standardization: This transducer system meets the rigorous mechanical and electrical requirements of the American Petroleum Institute (API) 670 standard. This compliance guarantees the reliability, accuracy, and interchangeable performance required by global oil, gas, and power generation facilities.

• Electromagnetic Noise Rejection: The shielded driver housing and specialized cable design minimize the impact of electromagnetic interference (EMI). This feature prevents false signals and "ghost" vibrations in industrial environments saturated with high-voltage equipment and variable frequency drives (VFDs).

FAQs

1. Does this system include the extension cable?

The CON021 driver and PR6423/010-100 probe form the core of the system. However, a complete transducer loop requires a specific length of extension cable (typically 5m or 9m total system length). Always verify your required total length before finalizing your order to ensure correct calibration.

2. Can I use this sensor with non-ferromagnetic shafts?

The system is factory-calibrated for ferromagnetic steel (AISI 4140). Using the sensor with other materials, such as stainless steel or aluminum, will significantly alter the sensitivity and linear range. If your shaft material differs, you must recalibrate the driver or provide a material correction factor.

3. Is the CON021 driver compatible with other EPRO probe models?

The CON021 driver must be matched with the PR6423 series to maintain the specified 7.87 V/mm sensitivity. Attempting to pair the driver with a different probe series (e.g., PR6422 or PR6424) will result in inaccurate displacement readings and potential system errors.

4. What is the recommended mounting gap for the PR6423 probe?

For standard vibration monitoring, set the mechanical gap to the center of the linear range (typically around -10V DC output). This provides sufficient room for the shaft to move both toward and away from the probe tip without clipping the signal.
