EPRO PR9268/203 – 100 Electrodynamic Velocity Sensor

The EPRO PR9268/203 – 100 is an electrodynamic velocity sensor, falling under the well – regarded PR9268 series by EPRO. EPRO, a company with a strong reputation in the industry, specializes in machinery protection and condition monitoring solutions. This sensor plays a crucial role in industrial applications, especially in the monitoring of rotating machinery.

Its working principle is based on electromagnetic induction. The sensor consists of a seismic block and a measuring coil supported by a cartridge. When the sensor housing vibrates, the measuring coil, which is the measuring element, moves within the magnetic field of a circular magnet. This relative motion generates a voltage signal that is directly proportional to the vibration speed of the object being monitored. As a result, this voltage output can be effectively utilized to measure and monitor the vibration speed or dynamic displacement of industrial equipment. This makes it an ideal choice for applications where precise vibration monitoring is essential, such as in steam, gas, and hydro turbo machinery, as well as compressors.
