SHOWA SOKKI 1500EX Pressure-resistant explosion-proof vibration switch Vibro switch
Made in Japan
Manufacturer: SHOWA SOKKI
Model: 1500EX
Features
- Firstly, there’s a pressure-resistant explosion-proof vibration switch with an integrated detector.
Secondly, this pressure-resistant explosion-proof vibration switch promptly detects abnormal vibrations and activates an alarm.
Additionally, vibration monitoring of rotating machines, plant equipment, and the like is feasible.
Notably, it is compact and cost-effective, and it can monitor vibrations with high accuracy up to 2 steps.
Furthermore, you can select the vibration mode from acceleration, velocity, and displacement using an internal switch.
Also, you can set the alarm level from 1 to 99% using the internal digital switch. To add, you can establish the alarm delay up to 60 seconds to avert malfunction.
Lastly, the housing boasts a pressure-resistant explosion-proof structure, and a flexible conduit connects the detector and amplifier.
