Charge output type Accelerometer
NP-2000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-2000 series offers seven types, ranging from ultra-compact models weighing 0.2 g to general-purpose and high-temperature resistant types. You can select the optimal sensor according to your purpose, operating conditions, and application.
Because it is a charge output type, a charge amplifier is required, but it can generally be used at higher temperatures compared to models with a built-in preamplifier.

*1: Sensor sensitivity varies from unit to unit; the stated value is a shipping standard and not measurement accuracy. By calibrating according to the respective sensitivity value, all sensors can measure under the same conditions and with the same accuracy.
*2: fc is a value determined by the time constant with the charge amplifier (for example, when used with CH-1200A, fc will be 1 Hz (±0.5 dB range)).
*3: Cable not included.
*4: Connector and cable not included.
* The sensor noise of the NP-2000 series is the "input-referred noise level" of charge amplifiers such as the CH-1200A.
