Photo (NP series Acceleration Pickups)

This sensor converts mechanical vibrations into electric signals in proportion of vibration acceleration.
Since 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., you can select them according to your uses. In addition, the series consist of the built-in preamplifier type (voltage output type)
and the charge output type, enabling you to select the one that is ideal for your temperature and vibration environments.

 

Features (Piezoelectric type accelerometer)

  • Selection of built-in preamplifier or charge output types

  • 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

*1:The sensitivity varies from model to model (individual differences). The values given in the above table are the standard values at the time of shipment, not the measurement accuracy values. 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
*3.Conforms to JIS C 0920 Protection Class 7.
*4:Operating temperature range is for the main unit only. The operation range when the cable is -25 to 105°C.
