SHOWA SOKKI 9401 Sensor amplifier for PLC

Made in Japan
Manufacturer: SHOWA SOKKI
Model: 9401
Features
The developers designed MODEL-9401 as a vibration sensor amplifier for PLCs (programmable logic controllers) that aggregate IoT data. It combines with various vibration sensors for diverse applications and environments, providing the PLC with real-time, highly accurate vibration waveform information.
Usage
- Maintenance of machining accuracy in machine tools involves the detection of cracks in press dies, as well as monitoring abnormal vibrations in motors, pumps, etc.
Additionally, vibration monitoring is crucial for motors and reduction gears, especially in automobile factories where conveyors and lifters are prevalent.
Moreover, product abnormality diagnosis on inspection lines, preventive maintenance of various rotating machines, and malfunction checks of production equipment are essential. - Lastly, vibration monitoring is essential, even in explosion-proof areas.
