The EPRO PR6424/119-000 is a high-performance 16mm eddy current sensor designed for precise non-contact measurement of shaft displacement, position, and vibration in industrial rotating machinery. Part of Emerson's PR6424 series, this sensor utilizes advanced eddy current technology to deliver superior resolution and linearity over a wide measurement range, making it ideal for critical turbomachinery monitoring applications where traditional contact-based measurement systems would be difficult or inefficient.

The PR6424/119-000 sensor is specifically engineered for use with EPRO's MMS 3000 and MMS 6000 machinery monitoring systems, providing reliable data for machine condition monitoring, process control, and machinery diagnostics. Its compact 16mm diameter sensor head allows installation in space-constrained applications while maintaining high measurement accuracy.

Key performance specifications include a sensitivity of 4 V/mm (101.6 mV/mil) with ±1.5% linearity, static measurement range of ±2.0 mm, dynamic measurement range of 0 to 1,000 µm, and nominal air gap of approximately 2.7 mm (0.11"). The sensor offers a resolution of 0.001 mm and typical accuracy of ±0.001 mm, with response time less than 1 ms. Long-term drift is less than 0.3%.

Built for harsh industrial environments, the PR6424/119-000 operates across an extended temperature range of -35°C to +180°C (-31°F to +356°F), with capability to withstand temperature excursions up to 200°C (392°F) for less than 4 hours. The sensor housing is rated IP67, providing dust-tight protection and resistance to temporary immersion in water. It can withstand pressure up to 10,000 hPa (145 psi) and offers shock and vibration resistance of 5g at 60Hz at 25°C.

The sensor requires a supply voltage of 10 to 30 VDC and provides customizable analog output options including 4-20 mA and 0-10 V. It is compatible with shaft diameters of ≥80mm and weighs approximately 200 grams (including 1 meter of cable without armor).

The PR6424/119-000 is widely used in critical applications including steam turbines, gas turbines, hydro turbines, compressors, pumps, and fans for measuring radial and axial shaft dynamic displacement, eccentricity, position, and speed/key monitoring. Its rugged design and high accuracy make it suitable for applications in power generation, oil and gas, chemical processing, and other heavy industrial sectors requiring continuous machinery health monitoring.

When installing the PR6424/119-000 sensor, it must be used as part of a complete measurement system including an appropriate extension cable (e.g., CON021 series) and a compatible signal converter (preprocessor) such as the CON011 or CON021, which provides power to the probe and demodulates the signal into a voltage proportional to the gap.
