PR9268/301-000 (EPRO/Emerson High-Temperature Type Bearing Vibration Sensor)

PR9268/301-000 is a high-temperature version of an inductive magnetic-electric bearing vibration sensor (bearing vibration), specially designed for high-temperature conditions ranging from -20℃ to +200℃. It has excellent low-frequency performance and high sensitivity, and is compatible with the TSI system. 

Model Disassembly (9268/301-000)
