Charge output type accelerometer
NP-2000シリーズ
An acceleration sensor that extracts the amount of mechanical vibration as an electrical signal proportional to the vibration acceleration.
The NP-2000 series offers seven types, ranging from ultra-compact types with a mass of 0.2 g to general-purpose types and high-temperature compatible types. You can select the optimal sensor according to the purpose of use, usage conditions, and application.
Since it is a charge output type, a charge amplifier is required, but compared to built-in preamplifier types, it can generally be used at higher temperatures.

*1: Sensor sensitivity varies by individual (individual differences); the stated values are shipping standards and not measurement accuracy. By performing calibration according to each sensitivity value, any sensor can measure under the same conditions and accuracy.
*2: fc is a value determined by the time constant with the charge amplifier (for example, when using CH-1200A, fc will be 1 Hz (±0.5 dB range)).
*3: Cable not included.
*4: Connector part, cable not included.
※ The sensor noise of the NP-2000 series will be the "input equivalent noise level" of charge amplifiers such as CH-1200A.
