Accelerometer (Charge Output Type)

NP-2000 Series

 

Photo (NP series Acceleration Pickups)

This sensor converts mechanical vibrations into electric signals in proportion of vibration acceleration.
You can choose the one that is ideal for your purpose,conditions,applications etc. from wide variety of selection.

Charge amplifier is necessary because it is a charge output type, however, compared to pre-amplifier built-in type, it can be used at higher temperature in general.

 

 

Features (Piezoelectric type accelerometer)

  • The seismo-type*1 sensor requires no reference point for measurement.
  • Compact and light weight, easy to mount and easy handling.
  • Wide dynamic range, micro acceleration measurement available.
  • Mechanical strength is suitable for measurement of large acceleration or impact acceleration. 
  • High resonance frequency makes the measureable frequency range wider. Wide band frequency can be measured without waveform distortion. 
  • 6 kinds of sensors are provided such as ultra compact type (0.6g), general purpose type, and heat-resistant type.
  • Charge amplifier is required. Can be used in higher-temperature environment compared to a built-in preamplifier type. 

* Vibration system where M is mass, K is the spring constant, and C is the viscosity resistance.

*1:The sensitivity such as ±0.5 dB and ±1 dB represents sensitivity variation for each sensor ( individual difference), not the measurement accuracy. Performing calibration for each sensor according to its respective sensitivity value enables measuremet to be performed under the same conditions and with the same accuracy, irrespective of the sensor type.

*2:The fc value is determined by the time constant with respect to the charge amplifier.

*3:Not including a cable

*4:Not including a cable and connector part.

 

*Noise of the NP-2000 series is equivalent to "conversion input noise level" of a charge amplifier used, such as CH-1200A charge amplifier.
