How To Measure Current

Data Acquisition > 4-20mA Current Loop …current is always measured indirectly from an external sensor that produces a voltage output that is proportional to current. Since the only difference between a voltage and current measurement is the scaling that you apply to the result, voltage measuring instruments are almost always used to measure current.   Read More

Learn the Importance of Isolation In Four Easy Lessons

Data Acquisition > Voltage The concept of isolation when applied to¬†instrumentation can be difficult to grasp for many who do not have formal instrumentation training or experience. Yet, an understanding of what it is, why it’s important, and when you need it, is fundamental for safe and productive measurements in so many measurement applications. This Read More
