Monitoring and dara acquisition are very important in order to learn the process and improve it.
In one of the biggest semiconductor factory, 200 measuring points are needed to be reported few times a day.
For years, this job has been done by few persons which is very in-efficient, and wiring 200 points is complicated and cost a lot of money.
Then we got into it with Smartnext wireless system based on RF conductivity.
We supplied 200 wireless transmitters with 4-20ma input that were integrated with the 200 DP sensors in the clean rooms (we also supplied the sensors).
The 200 transmitters send the signal to 7 Control-Panels, and each Control-Panel was connected by Ethernet with MODBUS communication to the factory main SCADA system.
