SHOWA SOKKI 2503 Vibro converter
Made in Japan
Manufacturer: SHOWA SOKKI
Model: 2503
Features
- In addition to general vibration monitoring systems, it can be used for diverse purposes, such as measurement in harsh environments and providing intrinsically safe explosion-proof support.
Specifically, the Vibro converter MODEL-2503 is a versatile system that accommodates various sensors and specifications.
For instance, a vibration monitoring system using the intrinsically safe explosion-proof detector MODEL-2450EX is composed of a detector situated in a hazardous zone, paired with a barrier (safety barrier), and integrated with MODEL-2503.
Notably, beyond DC4-20mA, there exist two output systems, one catering to vibration raw waveform AC±2V.
Hence, it allows connectivity to various PLCs and facilitates observation on a digital monitor. This functionality further enhances the IoT compatibility of equipment.
