SHOWA SOKKI 2702 Vibration detector for earthquake monitoring

Made in Japan
Manufacturer: SHOWA SOKKI
Model: 2702

Features

  • A vibration detector designed specifically for seismic motion monitoring is not only crucial but also ideal for the safe shutdown of plant equipment. Furthermore, it supports evacuation standards in the event of an earthquake. Impressively, it outputs the vibration acceleration, which is obtained by synthesizing the 3-direction vector of XYZ, at a standard 4-20mA.

    Moreover, this detector is capable of outputting seismic motions ranging from 0-400 gal. To ensure accuracy, the frequency band of the detector is carefully matched to the seismic motion band. Users will benefit from its real-time output, yet they have the option to switch to peak hold output if needed.

    Additionally, this is a waterproof type, complete with mounting feet, which simplifies the process of grounding. This thoughtful design ensures durability and ease of installation, making it a reliable choice for monitoring seismic activity and protecting infrastructure.
