Ono Sokki NP-2000 Series Accelerometer Charge Output Type

NP-2000 series sensors from Ono Sokki convert mechanical vibrations into signal proportional to vibration acceleration.

Various types are available such as extra small type weighing  only 0.4g, 3-axis type for measuring acceleration in the x, y and z  directions, water-tight type, high sensitivity type, etc.

Features (Piezoelectric type accelerometer)

· Charge output type

· The seismo-type sensor requires no origin

· Smaller, lighter and tougher than other types, and the dynamic range is wider

· High resonance frequency makes the measurable frequency range wider

Charge convertor (CH-6130/CH6140 etc.) is required to use for NP-2000 series.
*1 : ±0.2dB is the variation range of the type (difference between individuals), but not the accuracy. Performing calibration for each of the sensors according to its respective sensitivity values enables measurement to be performed under the same conditions and with the same accuracy, irrespective of the sensor type.
*2 : fc determined by charge amplifier time constant setting
