EPRO PR9268/202-100 Shaft vibration probe

EPRO PR9268/202-100 Shaft vibration probe information can be summarized as follows:

Overview:
This is a shaft vibration probe manufactured by EPRO, model PR9268/202-100.
It is mainly used to measure shaft vibration, especially in turbine machinery such as steam, gas and hydraulic turbines, compressors, pumps and fans.
Technical specifications:
Measuring range/limit: up to 1500μm possible (the specific range may vary depending on the actual application).
Frequency range: 4 to 1000 Hz (240 to 60,000 CPM), indicating that the probe is capable of covering a wide range of vibration frequencies.
Sensitivity: At 80 Hz, 20°C, the sensitivity is 28.5 millivolts/mm/SEC (or 723.9 mV/inch/SEC) for a 100 ohm resistance.
Maximum acceleration: 10g (98.1m/s²) in continuous operation, up to 20g (196.2m/s²) in intermittent operation.
Damping: natural frequency is about 4.5Hz, damping is about 3.6Hz.
Resonant frequency: about 5 Hz.
Dynamic performance: Low lateral sensitivity to ensure the accuracy of measurement results.
Design and Features:
The probe uses a dynamic sensor design, with part of the measuring coil connected to the seismic element, located within the permanent magnet field.
Damping of the measuring element is achieved through the damping cylinder and can be adjusted through external wiring and Settings.
The probe is designed for vertical and horizontal operation and is suitable for vibration measurement in different directions.
Applications:
It is especially suitable for situations where mechanical vibration needs to be accurately measured and controlled to ensure stable operation and extended service life of the equipment.
