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 ...

To reduce noise and voltage drops in analog voltage signals, the market place has adopted an analog current (4-20mA) output as its sensor signaling standard. A very robust signal, 4-20mA current ...

Use of 4-to-20-mA current loops involves more than just a simple series connection between sensor, display, and power supply. The point where a sensor takes a measurement is, at times, many yards away ...

The MAX12900 ultra-low-power, highly integrated 4–20-mA sensor transmitter from Maxim Integrated Products has a 10-ppm/°C voltage reference for up to 3.5 times lower drift compared to traditional ...

Back in the “good old days,” controls were all analog and mechanical, which simply means that they acted in a directly connected and variable manner based on a change in force. Both pneumatic (air ...
