Q & A

What is industrial instrumentation?

Industrial instrumentation is the science and technology of measuring and controlling process variables like pressure, temperature, level, flow, pH, and conductivity to ensure the safe, efficient, and automated operation of complex industrial systems.

What is the role of sensors in industrial instrumentation?

Sensors act as the 'eyes' of the system, detecting and measuring process variables like temperature, pressure, and flow, and sending this data to controllers for processing and action.

How do controllers function in industrial systems?

Controllers are like the 'brain' of the system, receiving data from sensors and making decisions based on that data to control actuators, which adjust the process parameters to maintain desired conditions.

What is a PID controller and how does it work?

A PID (Proportional-Integral-Derivative) controller is a feedback control method that adjusts a process continuously to keep it as close as possible to a desired value by correcting errors based on proportional, integral, and derivative calculations.

Can you explain what P, I, and D stand for in a PID controller?

P stands for Proportional, I for Integral, and D for Derivative. These components help in adjusting the process by considering the current error (P), the cumulative past error (I), and the rate of change of the error (D).

Where are PID controllers commonly used?

PID controllers are widely used in applications such as boilers, robotics, thermostat systems, cruise control in cars, and other processes where maintaining a constant variable is crucial.

What historical figure is associated with early feedback control systems?

Cornelius Drebble is known for creating one of the first feedback control devices, a water temperature regulator for ovens, in the 1600s. Later, James Watt's steam engine governor (1788) also played a foundational role in feedback control systems.

How did industrial instrumentation evolve in the 20th century?

Industrial instrumentation evolved from pneumatic controllers to electronic instruments and, eventually, to modern digital smart devices, which provide more precise and flexible control over industrial processes.

What are some real-world examples covered in this series?

The series covers real examples like a boiler water level system, a wastewater disinfection process, and a chemical reactor temperature loop, providing practical applications of instrumentation in various industries.

How will this series help viewers understand industrial instrumentation?

This series will help viewers understand industrial instrumentation by breaking down complex concepts, such as how to read schematics, recognize common devices, and understand the signals that drive them, all based on the open-source textbook 'Lessons in Industrial Instrumentation' by Tony Kalt.
