Design and Deployment of Wireless Monitoring System for 4-20mA Current Loop Sensors

In this paper, we present a wireless monitoring system for the industry that collects data from 4-20 mA current loop sensors. We try to make this system easy to handle even for non-wireless expert. To prove this, we asked non-wireless expert to run the field tests of this system for more than 30 times under different environments. From the field test results, we found that non-wireless experts could set up the system properly without external help and the data was corrected sufficient for monitoring. The architecture of the system and the results of the field test are discussed.
