Jayanand Engineering Instrument & Control Engineer Interview Questions and Answers

DCS and PLC are control systems used in industrial automation to monitor and control processes.

• DCS stands for Distributed Control System, used for large-scale industrial processes with multiple control loops.

• PLC stands for Programmable Logic Controller, used for smaller-scale automation tasks with discrete inputs and outputs.

• DCS typically has a centralized control room with multiple operator stations, while PLCs are st...read more

Simulink is a graphical programming environment for modeling, simulating, and analyzing dynamic systems.

• Simulink is used for designing and simulating control systems, signal processing systems, and communication systems.

• It provides a block diagram environment where you can connect blocks representing system components.

• Simulink models can be used for real-time simulation, hardware-in-the-loop testing, and rapid prototyp...read more

Questions related to general working ranges, temperature sensors, and purpose of instruments for Instrumentation Engineer position.

• General current and voltage working ranges of instruments depend on the type of instrument and its application.

• Temperature sensors types include thermocouples, RTDs, thermistors, and infrared sensors.

• Thermocouples work on the principle of Seebeck effect, while RTDs work on the principle of ...read more
