Industrial temperature sensors are widely used with 4–20mA current-loop transmitters in industrial control and automation. In the current loop the temperature sensor converts a temperature into a ...
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 ...
The low output voltage level of the analog sensor and the long distance to the control room together constitute significant system design challenges. Here are clues on how to solve them. The 4-20 mA ...
