The process of measuring and controlling various quantities in production processes using various instruments or industrial elements is defined as industrial instrumentation.

To control any quantity, one must primarily measure that particular quantity. After measuring the desired quantity, the measured values ​​are transmitted for indication, calculation or control purposes, either with manual or automatic operation.

In an automatic control operation the quantity can be controlled using the control signal sent by the CPU to the control devices.

In practice, the sensors read the different field data such as flow, pressure, displacement, vibrations, etc., and transmit them to the control systems that will regulate these variable quantities.

In industry, control is usually carried out by programmable logic controllers (PLC) or distributed control systems (DCS).

SCADA systems are crucial to industrial businesses, helping to maintain efficiency, process data to make smarter decisions, and communicate system issues to reduce downtime.

This automatic data acquisition and supervisory control system made up of software and hardware allows companies to:

• Control industrial processes locally or remotely.
• Monitor, collect and process data in real time.
• Interact directly with devices such as sensors, valves, motors, and the HMI interface.
• Sequentially record in a file or database events that occur in a production process.
• Create alarm panels in machine failures due to operating problems.
• Manage Maintenance with the magnitudes obtained.
• Quality control using the data collected.
