TEDS compatible Ultrasensitive Tri-axial Accelerometer

The NP-7320N10 is a tri-axial accelerometer with a built-in preamplifier. Excellent for measuring low frequency vibrations such as ground vibrations and floor vibrations during machine operation.

It allows direct input to analyzers and recorders that have a built-in constant current amplifier, such as FFT analyzers DS-5000 series and CF-9000A series. Additionally, when connecting to a TEDS compatible device, information such as sensitivity is automatically loaded, thus, no calibration work will be required. It minimizes human-errors and reduces the setting time.


High sensitivity, Low noise
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 IP67 (JIS C 0920:2003)
Enables to use in outside with excellent waterproof performance.

Built-in preamplifier type
Enables to input directly to the devices with built-in constant current amplifiers such as DS-5000 series, CF-9000A series. Since no dedicated amplifier is required, it is easy to carry the device and prepare for measurement.

TEDS compatible
No need to enter calibration values manually during calibration and they are automatically loaded. These reduce the setup time and prevent human errors.

Conforming to CE marking
The CE mark is a mark that indicates that the target product meets "the essential requirements of each directive stipulating the health and safety protection of product users and consumers" for the New Approach Directive established by the European Commission. Therefore, the products with CE mark can be exported overseas.
