Amul Industries Instrument Engineer Interview Questions, Process, and Tips

UUC and CSU are two different methods of calibration used for instruments.

• UUC stands for Universal Use Calibrator and is a portable device used for calibration of instruments.

• CSU stands for Centralized Standards Unit and is a fixed device used for calibration of instruments.

• UUC is used for field calibration while CSU is used for laboratory calibration.

• UUC is less accurate than CSU but is more convenient to use.

• CSU is m...read more

The range of pressure transmitter used in our plant is between 0-1000 psi.

• The pressure transmitter range is determined by the process requirements.

• The range can vary depending on the type of equipment and application.

• The transmitter range is usually specified by the manufacturer.

• The range can be adjusted or calibrated as needed.

• In our plant, the pressure transmitter range is between 0-1000 psi.

• This range is suitable fo

Digital and analog inputs and outputs are used in PLCs to receive and send signals. Digital signals are binary, while analog signals are continuous.

• Digital inputs and outputs use binary signals to communicate with other devices.

• Analog inputs and outputs use continuous signals to measure and control variables such as temperature, pressure, and flow.

• Digital signals are either on or off, while analog signals can have a ra...read more

Solenoids are electromechanical devices that convert electrical energy into linear motion.

• Solenoids use the principle of electromagnetic induction to create a magnetic field that moves a plunger or rod.

• They are used in various applications such as door locks, valves, and starter motors.

• Solenoids can be either push-type or pull-type depending on the direction of the linear motion.

• They are commonly used in automation and...read more

Capacitors store energy and inductors resist changes in current, causing transients in DC supply.

• Capacitors store energy and can discharge quickly, causing voltage spikes or dips in the DC supply.

• Inductors resist changes in current, causing voltage spikes or dips in the DC supply when the current changes rapidly.

• Transients can be mitigated by adding resistors or diodes to the circuit.

• Examples of transients include swit...read more
