Epson's M-A552 accelerometer is an ideal choice for structural health monitoring

Epson acceleration sensing technology helps achieve safer social infrastructure

Seiko Epson (TSE: 6724, "Epson") has added two new high-performance products to its three-axis accelerometer lineup. M-A552AC1 supports CAN * 1 communication protocol, while M-A552AR1 supports RS-422 * 2. The samples of the new product will start shipping in the summer of 2019 and are scheduled for mass production in the spring of 2020.

Epson's accelerometer was first launched in 2014 and has been used in a range of applications, earning a good reputation for excellent performance and quality. The aging social infrastructure and the soaring costs of infrastructure maintenance, monitoring, and updating are considered serious social problems faced by countries and communities. This understanding has driven the growing demand for technologies that utilize sensors to monitor structural health.

In May 2019, Epson began shipping samples of another new type of accelerometer, M-A352, to promote the dissemination of serious structural health monitoring technology. M-A352 provides necessary noise performance of 1 µ G/√ Hz or higher (servo accelerometer * level 3), as well as excellent durability and manufacturability, ensuring stable supply and cost competitiveness.

M-A552AC1 and M-A552AR1 have the same performance as M-A352, but come standard with CAN and RS-422 interfaces, respectively. These interfaces are widely used in industrial applications, and the demand for them has always been strong. They are placed in metal packaging, providing waterproof and dustproof protection equivalent to an IP67.

This high-level protection of elements enables these products to be widely used in industrial applications that require long-distance and excellent stability and reliability.

*Controller Area Network (CAN) is a network protocol widely used in automotive equipment and industrial products* RS-422 is a serial communication standard primarily used for industrial products* 3 servo accelerometers are high-precision accelerometers widely used for earthquake detection and measurement of minor vibrations in civil engineering structures.

These products provide the high-level performance required for structural health monitoring and other industrial applications, as well as the flexibility to make the system easy to build. They also make it easy to build multi node (multi-point) measurement systems, synchronous measurement systems, and other complex and precise measurement systems. Due to their ease of installation, connection, and use, these accelerometers can greatly reduce customer system development time even in outdoor and other harsh environmental conditions.

Product features
