Murata Launches Industrial 3-Axis Accelerometer with High Offset Stability

Recent advancements in accelerometer technology highlight improvements in accuracy, stability, and integration of AI for dynamic motion analysis across various applications. A new dynamic calibration procedure for triaxial accelerometers uses a simple rotating wheel setup to estimate both sensor parameters and bench motion without prior knowledge, providing high precision validated on synthetic and real data. Bosch introduced the BHI385, a compact sports inertial measurement unit with embedded AI capable of recognizing complex motion patterns and evaluating quality of movements, targeting sports, fitness, and gaming markets, although it is not yet available. In the industrial sector, Murata released the SCA3400-D01, a 3-axis accelerometer featuring exceptional offset stability, low noise density, and linearity, enabling manufacturers to maintain accuracy over temperature variations and lifespan without frequent recalibration. This sensor also offers user-selectable dynamic ranges and low-pass filtering, self-diagnostics, and SPI communication, making it suitable for machine control, inertial measurements, and structural health monitoring. These innovations demonstrate significant progress in accelerometer precision and adaptability for both consumer and industrial uses.
