0~5v output road roller vibration measure sensor low deviation ▶ PRODUCT INTRODUCTION The AKM390 three-axis Vibration sensor is a widely used
acceleration sensor series product independently developed and
produced, which can be applied in multiple fields such as vibration
testing and impact testing. The product adopts analog voltage
output. AKM390 is a single crystal silicon capacitive sensor,
consisting of a silicon chip that has undergone micro mechanical
processing, a low-power ASIC for signal adjustment, a
microprocessor for storing compensation values, and a temperature
sensor. This product has low power consumption, has been
calibrated, has a sturdy structure, and stable output. The new
electronic configuration provides solid-state power for reset and
comprehensive protection against over voltage. This series of
products features sturdy structure, low power consumption, and
excellent deviation stability, ensuring the reliability of product
output. ▶ PRODUCT FEATURES - Three axes (X, Y, Z)
