Epson’s M-A352 accelerometer for structural health monitoring
20/12/2018
Seiko Epson Corporation has developed a new high-performance three-axis accelerometer, the M-A352. Samples will begin shipping at the end of 2018, with volume production scheduled for the spring of 2019.Epson’s accelerometers, first launched in 2014, have been used in an array of applications, earning an excellent reputation for outstanding performance and quality. Ageing social infrastructure and the soaring cost of infrastructure maintenance, monitoring and renewal are recognised as serious problems for nations and communities. This recognition is driving a growing need for technology to monitor the health of structures using sensors.
Epson has developed the new M-A352 to give momentum to the spread of serious structural health monitoring technology. The M-A352 provides the necessary noise performance of 1 µG/√Hz or better (servo accelerometer*1 class), along with outstanding durability and manufacturability, ensuring stable supply and cost competitiveness. Offering a rare combination of excellent accuracy and high durability, the M-A352 can be used for applications where high-accuracy measurements are typically difficult to take.
Product features:
- High shock resistance: 1200 G (quadruple that of the M-A351, Epson’s existing product)
- Low noise: 0.5 µG/√Hz.
- Wide dynamic range: 27 bits
- Original noise resistance direct digital conversion technology
- Low-jitter external trigger function that enables high-accuracy time synchronisation in multi-node measurement.
This accelerometer can be used in structural health monitoring (for example of buildings, roadway structures, bridges, tunnels and steel towers), earthquake detection, environmental vibration measurement, industrial equipment monitoring, unmanned vehicles (for example terrestrial vehicles and undersea probes) and for the measurement of the vibration and path of industrial equipment and vehicles.
