Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop. All that’s needed for both outputs is an Arduino and an ...

Mike: Nearly every analog instrument uses the 4-20 mA loop. Field transmitters, positioners, and variable frequency drives ...

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

Typically, process control loop feedback strategies use “flow” as the manipulated variable to control the desired variable. To achieve this, a controller output signal is sent to a control flow valve ...

If you would prefer to streamline the process, look for an automation-as-a-service business that can not only offer managed services but also provide an outsourced human-in-the-loop. 4.
