Automation is the use of control systems such as numeric control, programmable logic controllers (PLC), etc to control industrial machinery and processes. It has had a notable impact in a wide range of highly visible industries beyond manufacturing.

The main advantages of automation are: -
• Replacing human operators in tedious task.
• Replacing human in tasks that should be done in dangerous environment.

There are various automation tools: -
• Artificial neural networks (ANN)
• Distributed control system (DCS)
• Human machine interface (HMI)
• Supervisory control and data acquisition(SCADA)
• Programmable logic controller (PLC)
• Programmable automation controllers (PAC)
• Instrumentation
• Motion control
• Robotics
Airox Nigen has extensive experience in providing distributed control system (DCS), Human machine interface (HMI), Supervisory control and data acquisition (SCADA), Programmable logic controller (PLC) and Instrumentation used in its product.
Instrumentation is used to measure physical values such as pressure, flow, level , temperature, etc. An instrument is a device that measures or manipulates variables such as flow, temperature, level, or pressure. Instruments include many varied contrivances which can be as simple as valves and transmitters, and as complex as analyzers.
