Bulit-in Preamplifier / Charge Output Type
Tri-axial Accelerometers

Office

The tri-axis acceleration detector is an accelerometer that can output electric signals in proportion of vibration acceleration, which has been converted from mechanical vibrations, at the same time from XYZ three vibration directions. Various types of accelerometers are provided including built-in preamplifier type, charge output type, and TEDS compatible type.

Features

  • 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
  • Selectable from various types according to the purpose or conditions of use
  • TEDS compatible sensors are available

*1: The sensitivity such as±10% represents sensitivity variation for each sensors (individual difference), not measurement. By performing calibration according to each sensitivity value, any sensors can measure with the same accuracy under the same conditions

*2: Conforms to IEEE1451,4-2004 Template ver.1.0

*3: Not included a cable

*4: EMC Directive: EN 61326:2021 RoHS Directive: EN IEC 63000:2018.

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