SHOWA SOKKI 2502 Vibration Monitoring Sensor

Made in Japan
Manufacturer: SHOWA SOKKI
Model: 2502

Features

  • This is a general-purpose, low-cost vibration sensor that outputs 4 to 20mA with an integrated sensor and amplifier. Furthermore, it serves as a low-cost, simple vibration monitoring sensor, which is ideal for controlling and monitoring rotating machines. Specifically, there are three types of measurements available: displacement, velocity, and acceleration.Given that the output is a 4-20mA DC, you can directly connect it to recorders, indicators, sequence circuits, etc., which simplifies the setup process. Additionally, because the sensor and amplifier are integrated, there is no need for a separate vibration meter amplifier, thus reducing equipment costs.

    Moreover, it is designed as a 2-wire system that includes both power supply and signal lines, and conveniently, the connection polarity does not matter. This feature enhances ease of installation and reduces the likelihood of connection errors.

    You can also use it as a vibrometer or for vibrometer purposes by connecting it to a dedicated monitor or meter relay. This versatility makes it suitable for a wide range of applications.

    Lastly, it is compatible with the MVM type of Fuji Electric Co., Ltd., ensuring that it can be integrated into existing systems that utilize components from this well-regarded manufacturer.

Usage

For incorporation into rotating machines such as motors, pumps, and blowers.
As a vibration sensor for automatic inspection systems.
As a simple type dedicated vibration meter.
For equipment diagnosis of machine tools, chemical and manufacturing plants.
For other vibration measurements and monitoring.
