NP-3000 series Accelerometer (with built-in preamplifier)
This sensor converts mechanical vibrations into electric signals in proportion of vibration acceleration. "The NP-3000 series offers ultra-small masses of 0.4g, tri-axial type which can obtain vibration directions of XYZ at once, waterproof, high sensitive type, and so on. You can choose the most suitable detector according to the purpose of use, operation conditions, and applications. Since the preamplifier is built in the detector main body of the NP-3000 series, sensor signal input part can be made relatively inexpensively and it can be directly connected to analysis equipment such as our FFT analyzer."
