High sensitivity tri-axial Accelerometer
with Built-in Preamplifier
NP-7310
Features
· Ultra high sensitivity enables low frequency vibration measurement
Suitable for low frequency vibration measurement such as floor vibration which is generated at the time of equipment installation.· Tri-axial simultaneous measurement
Compared to the conventional one-axial measurement, more precise vibration measurement is available. Suitable for the structure analysis of building· Waterproof type (JIS C0929)/IP66 (JIS F8007)
Enables to use in outside with excellent waterproof performance.Built-in preamplifier type
Enables to input directly to the unit with built-in constant current amplifier such as DS-2000 series, DS-3000 series, CF-7200A, CF-9000 series and CF-3650/3850 series, etc. It is easy to set, carry and measure at the site.
