Product Description
EPRO PR9268/705-000 Electrodynamic Velocity Sensor delivers precise casing vibration monitoring for critical turbomachinery. Unlike traditional eddy current proximity probes that measure relative shaft vibration, this sensor directly measures absolute vibration on machine casings, providing accurate and reliable data for condition monitoring and protection systems.
Designed for horizontal mounting, the PR9268/705-000 integrates seamlessly with Emerson EPRO monitoring platforms such as VM600 and AMS 6500. Moreover, its high sensitivity and linear response across a wide frequency range ensure effective detection of low-frequency vibration, helping prevent machinery damage before failures occur. The sensor's rugged IP67 stainless steel housing makes it suitable for extreme industrial environments, including steam turbines, gas turbines, compressors, pumps, and gearboxes.
