Earthquakes have always been a dark cloud hanging over people's heads. How to be informed in advance when an earthquake occurs and prevent greater economic losses has become a problem that many companies are preparing to solve. Seiko Epson has learned that the "Yure Mon Hyper" seismic intensity meter equipped with Epson M-A352 high-performance three-axis accelerometers produced by Tokyo Knowledge Foresight Inc. has passed the Japan Meteorological Agency's seismic intensity meter certification test (JMA). In early June, Knowledge Foresight's seismic intensity meter was the second seismic intensity meter equipped with Epson M-A352 accelerometers to obtain certification. The first one was the LA-352 seismic intensity meter manufactured by Tokyo Clovertech Inc., which was certified in January 2022.

M-A352 is an ultra low noise, high stability, and low-power three-axis digital output accelerometer using quartz precision processing technology. The multifunctional M-A352 combines high precision and durability, making it very suitable for various challenging applications such as SHM, earthquake observation, industrial equipment status monitoring, and pose detection of industrial machinery (i.e. engineering machinery/accessories, agricultural machinery/machinery, robots).

The M-A352 is packaged in a waterproof and dustproof metal casing, supporting CAN bus interfaces. This reinforcement device is suitable for industrial applications that require remote installation, remote wiring, and/or simplified development of multi node measurement systems, which require multiple devices to have precise synchronization performance.

Epson's accelerometer was first launched in 2014 and has been used in various applications, earning a good reputation for its excellent performance and quality. In recent years, the demand for better and more accurate systems to observe and monitor events such as oceans and frequent earthquakes has continued to grow. This has stimulated the demand for solutions using seismic intensity meters equipped with high-precision accelerometers.

The Japan Meteorological Agency only uses certified meteorological instruments in its meteorological observation facilities, and these instruments need to be reported in accordance with the Japan Meteorological Services Act. This latest seismic intensity meter is not a meteorological instrument, but if the device user needs certification to ensure accuracy, the Japan Meteorological Agency will conduct the same tests on other devices as meteorological instruments. Instruments used for meteorological observation and measurement must meet strict standards. Perform two types of tests based on the type of instrument. Structural testing is used to determine the suitability of materials, components, and combinations. Instrument error testing (performance testing) is used to determine the accuracy of individual instruments.

The seismic intensity meters of Clovertech and Knowledge Foresight have passed JMA's seismic measurement certification testing. They have excellent availability and accuracy, as well as a high level of durability. Meanwhile, the M-A352 accelerometer can provide the 1 required for seismic intensity measurement μ Necessary noise performance of G/VHz or higher (servo accelerometer level 2), as well as excellent durability and productivity.

Epson will improve its efficient, compact, and precise technology to achieve extremely precise and accurate sensing in a wide range of applications such as earthquake and environmental vibration measurement, health monitoring of large structures, and bridge monitoring, thereby helping to enhance community safety.
