product description

akm392 triaxial accelerometer is a widely used acceleration sensor independently developed and produced by rion technology, which can be applied to vibration testing, impact testing and other fields. the product adopts digital interface output, rs232/485/ttl is optional, and different address codes can be set. multiple sensors are connected in series for a long distance, which is convenient for multi-point measurement and data analysis. the akm392 is a monocrystalline silicon capacitive sensor consisting of a micromachined silicon chip, a low-power asic for signal conditioning, a microprocessor for storing compensation values, and a temperature sensor. this product has low power consumption, solid structure and stable output after calibration. the new electronic configuration provides solid state power for reset, providing protection against over-current. the long-term stability and deviation of the scale factor are typically less than 0.1% over the full scale range. this product has the characteristics of solid structure, low power consumption and excellent deviation stability, which ensures stable output reliability.
