SHOWA SOKKI 2403 Low frequency vibration sensor High sensitivity vibration detector

Made in Japan
Manufacturer: SHOWA SOKKI
Model: 2403

Features

This is an ultra-sensitive vibration sensor designed for the purpose of stably measuring minute vibrations at low frequencies.
The 2403 type vibration sensor is an ultra-high-sensitivity vibration sensor designed to stably measure minute vibrations at low frequencies .
Three outputs of acceleration, velocity and displacement can be taken out at the same time.
The dynamic range is 120 dB for acceleration output, 110 dB for velocity output, and over 100 dB for displacement output.
Unlike the servo type and electrodynamic type, it does not have moving parts, so it is durable and easy to handle.
Due to its unique structure, it can stably measure extremely small vibrations at low frequencies.
The waterproof structure allows measurement in adverse environments.

Monitor unit for vibration sensor.
As it is a portable type, it is easy to carry.
Since the power supply is a dry battery, there is mobility.
Acceleration, velocity, and displacement output can be obtained simultaneously.
The acceleration measurement range is 0.00001 to 10m/s2. This has a dynamic range of 120dB
