Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop.

I also observe how the disturbance I introduced affects the output, specifically establishing a ratio between the Cv disturbance and Pv response (process gain). A 1:1 reaction, as measured in ...

Luckily, industrial process engineers figured out how to deal with these problems a long time ago by using current loops for sensing and control.

One segment of a process control system. An open-loop control process requires human intervention, whereas a closed-loop system is entirely automated (see PID). See process control.

Some wonder if AI will replace PID control loops. The reality is that, instead of replacing PID, AI is stepping in to help keep things running smoothly without upending regulatory trust. Think of AI ...

Advanced process control (APC) has incorporated and will continue to incorporate new technologies and methodologies that allow refiners and petrochemical plant operators to achieve ...

This is an open loop (disturbance > math > manipulated variable > PROCESS > process variable), compared to a closed (i.e., PID) feedback loop (process variable > math > manipulated variable > PROCESS ...

All staff have been released with only minor injuries. — -- A group of inmates at a maximum security prison in Arkansas took control of part of the prison after stealing keys from ...

These configurable processors allow users to lock the laser to the cavity, inject the disturbance, and simultaneously measure the open-loop, closed-loop, and disturbance transfer functions.

Seven Chicago police officers were injured while responding to a call of a disturbance at the lobby of a business in the South Loop neighborhood Saturday morning.
