Accelerometer (with built-in amplifier) TEDS compatible
NP-7320N10

The NP-7320N10 is an accelerometer with a built-in preamplifier that can simultaneously measure in three axes. It excels at measuring minute vibrations such as ground vibrations and floor vibrations during machine operation.

The NP-7320N10 can be directly input to analyzers with built-in constant current drive (CCLD), such as the DS-5000 series and CF-9000A series FFT analyzers. Furthermore, when connected to TEDS-compatible equipment, sensitivity and other information are automatically read, eliminating the need for tedious calibration work. As a result, setting errors during manual calibration are prevented, and setup time is reduced.

Tri-axial Accelerometer NP-7320N10

Features

High Sensitivity & Low Noise
It can detect minute vibrations that humans cannot feel, such as floor vibration measurements due to equipment installation.

3-axis simultaneous measurement
Enables more precise vibration analysis compared to single-axis measurement. Ideal for structural analysis of buildings and more.

Waterproof structure IP67 (JIS C 0920:2003)
It has excellent waterproofing and can be used outdoors.

Built-in preamp
Direct input is possible for devices such as the FFT Analyzer DS-5000 series and CF-9000A series, which have built-in constant current drive (CCLD).
Since a dedicated amplifier is not required, it is easy to transport the equipment and prepare for measurements.

TEDS compatible
There is no need to input values during calibration, making it easy to read calibration values. This leads to a reduction in calibration time and prevention of human errors.

CE Marking
This mark indicates that the product satisfies the "essential requirements of the directives that specify the protection of health and safety of users and consumers" as established by the New Approach Directive set by the European Commission (a common European law). Therefore, it can be used overseas.
