EPRO PR9266-12 | Electrodynamic Velocity Sensor
The EPRO PR9266-12 is a high-sensitivity electrodynamic velocity sensor engineered for absolute vibration measurement in rotating machinery. It utilizes electromagnetic induction to generate a voltage signal proportional to the vibration velocity of the monitored surface. This sensor is fully compatible with Emerson’s MMS 3000 and MMS 6000 machinery protection systems.
Its reinforced housing ensures reliable operation under harsh industrial conditions, including high temperatures, mechanical shocks, and corrosive environments. Typical installations include turbines, compressors, fans, pumps, gearboxes, and other critical machinery.
