INDUSTRIAL INSTRUMENTATION

What is the instrumentation? 

The process in which the set of several interconnected electrical, measuring and control instruments to measure, analyze and control the electrical and non-electrical physical quantities is called Instrumentation. Basically, there are several types of instruments, such as electric, electronic and mechanical. Instrumentation is classified in turn into different types, such as electric instrumentation, industrial instrumentation, electronic instrumentation, mechanical instrumentation.

What is industrial instrumentation and what is it for? 

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

How does industrial instrumentation work? Industrial instrumentation is considered the science of measuring and controlling automated systems. Applications of this technology proliferate in technological research, industry and everyday life. From control systems for car engines to domestic thermostats, automatic aircraft pilots, drug manufacturing, power plants, oil and gas, refineries, etc.

The variables to be measured or controlled can be:

 Physical variables: 

Flow rate. 

Mass flow rate. 

Volumetric flow rate.

 Pressure. 

Temperature. 

Level. 

Liquid level. 

Solid level. 

Speed. 

Weight. 

Humidity. 

Dew point.

 Chemical variables: 

pH. 

Electrical conductivity. 

Redox.

Characteristics of Industrial Instrumentation 

The characteristics of industrial instrumentation in real-time applications are based on its architecture. In short, it consists mainly of sensors, transducers or input devices, controllers, processors, transmitters and actuators or output devices.

• Input instrumentation is used to measure, regulate physical quantities such as flow, level, pressure, temperature and so on.

• The output instrumentation includes control devices such as valves, regulators, switches and relays. These are intended to control the desired output variable, providing remote or automatic control capabilities. They are considered as final control devices or elements.
