EPRO PR9268/203-000 Electrodynamic Velocity Sensor
Overview
EPRO PR9268/203-000 is an electrodynamic velocity sensor, mainly used for absolute vibration measurement of key turbomachinery such as steam turbines, gas turbines, water turbines, compressors, pumps and fans, and can measure the vibration of the casing. It is installed vertically, allowing ± 30° installation angle deviation (no current injection), and can withstand continuous peak-to-peak acceleration of 10g (98.1 m/s²) and intermittent peak-to-peak acceleration of 20g (196.2 m/s²).
Function & Features
- PR9268/203-000 has a lateral sensitivity of 0.13 at 110Hz, which reduces the impact of lateral vibration interference on the measurement results.
- The mechanical limit peak-to-peak value of the vibration amplitude is 3000µm (some can reach 4000µm), which can measure larger vibration amplitudes.
- The amplitude linearity is less than 2%, ensuring the linear relationship between the output signal and the actual vibration amplitude within the measurement range.
- It can withstand continuous peak-to-peak acceleration of 10g (98.1 m/s²) and intermittent peak-to-peak acceleration of 20g (196.2 m/s²).
