Emerson EPRO ZW0502/1217/0211+PR6423/005-0F2 Eddy Current Sensor

Product Description

The ZW0502/1217/0211 + PR6423/005-0F2 is a high-precision non-contact displacement measurement system. It combines an 8mm Eddy Current Sensor (PR6423 series) with a dedicated signal converter/driver (ZW0502 series). This assembly is engineered for the continuous monitoring of critical rotating machinery, specifically measuring shaft vibration, axial thrust position, and differential expansion. By utilizing eddy current technology, it provides accurate, real-time data of conductive targets even in the presence of oil, water, or steam, making it a standard for turbine and compressor protection systems.

Key Engineering Features

• Non-Contact Technology: Measures distance without physical contact, eliminating wear and tear on both the sensor and the monitored equipment.

• Integrated Signal Processing: The ZW0502 driver converts the raw high-frequency signal from the PR6423 probe into a stable 4-20 mA output, allowing for direct connection to PLCs, DCS, or safety instrumented systems.

• Environmental Resilience: Designed to withstand the harsh internal environments of steam turbines and industrial gearboxes; the sensor head is resistant to high pressure and chemical contaminants.

• High-Speed Dynamic Response: Capable of capturing high-frequency vibrations, which is essential for early fault detection in high-speed turbomachinery.

• Matched Component Calibration: The "+" designation indicates a factory-matched pair, ensuring the driver is perfectly calibrated to the specific electrical characteristics of the 8mm probe for maximum linearity.
