EPRO PR9268/201-000 Absolute Vibration Velocity Sensor

The EPRO PR9268/201-000 is an electrodynamic absolute vibration velocity sensor under Emerson EPRO product line. It adopts seismic measurement principle to capture bearing housing absolute vibration, outputting analog voltage signal proportional to vibration velocity for machinery online monitoring systems.

This rugged sensor has low impedance output and strong anti-interference capability, directly compatible with MMS3000 and MMS6000 monitoring racks. It suits continuous operation under oil mist, dust and temperature fluctuation environments, widely used for turbomachinery maintenance and spare parts stocking in power and petrochemical industries.
