Accelerometer with Built-in Preamplifier
NP-3000シリーズ
Accelerometer extracts the amount of vibration in a mechanical system as an electrical signal proportional to the vibration acceleration.
The NP-3000 series offers a range of options, from ultra-compact types weighing just 0.4 g to 3-axis types that can capture XYZ vibration directions simultaneously, as well as waterproof and high-sensitivity types. You can choose the optimal sensor according to your purpose, operating conditions, and application.
The NP-3000 series incorporates a preamplifier within the sensor itself, allowing for relatively inexpensive construction of the sensor signal input section, and enabling direct connection to our analysis equipment such as FFT analyzers. TEDS-compatible Accelerometer have also been added to the lineup.
