SHOWA SOKKI 1500B Vibration switch Vibro switch

Made in Japan
Manufacturer: SHOWA SOKKI
Model: 1500B

Features

Firstly, it is compact and inexpensive, and it can monitor vibrations with high accuracy up to 2 steps.
Secondly, you can select the vibration mode from acceleration, velocity, and displacement using an internal switch.
Additionally, aluminum composes the housing with a drip-proof structure, and you can fix the cable with a cable gland (equivalent to IP64).
Furthermore, you can set the alarm level from 1% to 99% in 1% steps using the internal digital switch. To enhance reliability, you can set alarm delays up to 60 seconds to prevent malfunctions.
Lastly, it is possible to monitor all kinds of vibrations such as rotating machines, plant equipment, and large structures.
