Process-control applications usecurrent loops to send informationas an analog signal over long distanceswith high noise immunity. Using thethree-chip circuit in Figure 1, you canmeasure alternating ...
The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that ...
A new range of automotive-qualified current sensors is addressing the growing need for accurate, isolated current measurement ...
Editor’s note: This month we are pleased to have Colin Wells from Texas Instruments as our blogger. In modern industrial control systems, 4-20 mA current-loop transmitters remain one of the most ...
Imagine this scenario: There is a flow meter with 4–20 mA output setup. The switch is flipped, thereby turning it on. Then it is noted that the readings are off, and the required output is not shown.
