Interface between a power regenerative test platform and data acquisition system

At the University of Minnesota, a power regenerative test platform has been built which is used to understand the performance of a hydrostatic transmission in a wind turbine. To understand the performance, the test platform contains 27 sensors. These sensors are used to monitor the test platform with real-time measurements. The big problem is that the sensors give off a current signal and the data acquisition system reads voltage signals. The two cannot understand each other if there isn’t a translation. Therefore, a solution is designing a circuit that is cleaner and more organized that the current circuit. The circuit will serves as the converter of current signals into voltage signals. This way the data acquisition system can read what the sensors are sending and we, as experimenters, are given real-time measurements.
