Product Description
Emerson EPRO PR9268/201-000 Electrodynamic Velocity Vibration Sensor
Vertical Vibration Monitoring Sensor for Rotating Machinery Protection (MMS 6000/MMS 3000 Compatible)
1. Product Overview
The Emerson EPRO PR9268/201-000 is an electrodynamic velocity vibration sensor designed for vertical vibration measurement in industrial rotating machinery monitoring and protection systems. It uses a mechanical spring‑mass system to generate a voltage signal proportional to vibration velocity, integrating seamlessly with Emerson MMS 6000 and MMS 3000 machinery monitoring systems. With a frequency range of 4‑1000 Hz, sensitivity of 28.5 mV/mm/s, and robust construction (IP65 protection, EEx ib IIB/IIC Zone 1 certification), it delivers reliable vibration data for turbines, compressors, pumps, and fans in power generation, oil & gas, and petrochemical industries, ensuring machinery safety and operational efficiency.
