Emerson EPRO PR9350/04 LVDT Sensor

The PR9350/04 LVDT (Linear Variable Differential Transformer) Sensor by Emerson EPRO is a precision surface contact sensor designed for critical turbomachinery applications, including steam, gas, and hydro turbines, compressors, pumps, and fans. It measures dynamic displacement, position, and eccentricity in rotating machinery, such as shaft movement and vibrations. The PR9350/04 is built to operate effectively in challenging environments where high accuracy and reliability are required.

Features:

• Designed for Tough Environments: Built to withstand harsh conditions typical in turbomachinery applications such as turbines, compressors, and pumps.
• Radial and Axial Shaft Measurement: Suitable for monitoring both radial and axial displacement of shafts, as well as measuring eccentricity.
• High Sensitivity and Accuracy: With a sensitivity of 270 mV/V and a linearity error of just 2.5%, the sensor offers high performance for precise measurement of dynamic displacement.
• Wide Operating Temperature Range: Capable of operating in extreme temperatures from -20°C to +100°C, making it ideal for high-temperature industrial environments.
• Easy Integration: Comes with a connector for easy installation and integration into existing measurement systems.
