20 Top Anduril Technologies Interview Questions & Answers
Here/, we have prepared a list of the top 20 Anduril interview questions and answers that will help you in the interview process. Let’s start:
#1. What is Automation?
Ans: Automation is the delegation of human control functions to technical equipment to increase productivity, better quality, reduced cost, and increased safety working conditions.
#2. What are the different components used in Automation?
Ans: The components of the automation system include:
- Sensors for sensing the input parameters
- Transmitters for transmitting the raw signal in electrical form
- Control system which includes PLC, DCS & PID controllers
- Output devices/actuators like drives, control values
#3. What are the different control systems used in Automation?
Ans:
- PID controller-based control system
- PLC-based control system’
- DCS-based control system
- PC-based control system
#4. What is an Encoder?
Ans: An Encoder is a feedback device that converts mechanical motion into electrical signal. Usually, an encoder is a rotary device that outputs digital pulses which correspond to incremental angular motion. The encoder consists of a glass or metal wheel with alternating clear and opaque stripes that are detected by optical sensors to produce digital outputs.
#5. What types of sensors are used for measuring different parameters?
Ans:
- Temperature Sensors- RTD, Thermocouple, Thermistor
- Pressure Sensors- Borden Tube, Bellows, Strain Gauge
- Flow Sensors- Flow orifice, Flow Nozzle, Venturi Tube, Pitote Tube
- Level Sensor
- Density Sensor
#6. What is Transmitter?
Ans: A transmitter is an electronic device that is generally mounted in the field close to a sensor. The sensor measures physical variables such as temperature or pressure and outputs a very low-level electric signal. The basic function of the transmitter is to provide the correct electrical power to turn on the sensor and then read the low-level sensor signal, amplify it to a higher-level electrical signal, and send that signal a long distance to a control or read-out device.
#7. What is the difference between 2-wire, 3-wire, and 4-wire transmitter?
Ans: In the 2-wire transmitter, the power and data signals are transmitted through the same cable and the cable has two wires only. In the 3-wire transmitter, the data signal and power are transmitted with respect to common ground. The cable has 3 wires. In the 4-wire transmitter, two wires for power supply and two for data signals. The cable has 4 wires.
#8. What is a Smart Transmitter?
Ans: A smart transmitter is a device that uses a microprocessor as an integral unit. The smart transmitter has its memory and it can also be programmed. It has abilities to perform calculations, do self-diagnostics, and communicate with other devices.
#9. What is a Field Bus?
Ans: A Field Bus is a bus system that connects sensors and actuators to a control computer (PLC) for information exchange. Each manufacturer has designed its communication mechanisms for its fieldbus so that all sensors and actuators can exchange information without interference. Most field buses are based on the so-called master-slave method.
Ex- Profibus PA, Profibus DP, CAN Open, CC link, DeviceNet
#10. What is Actuator?
Ans: An actuator is a device that uses a form of power to convert a control signal into mechanical motion. From electric door locks in automobiles to ailerons on aircraft, actuators are all around us. Industrial plants use actuators to open valves, dampers, fluid couplings, and other devices used in industrial process control. The industrial actuator can use air, hydraulic fluid, or electricity for motive power. These are referred to as pneumatic, electro-hydraulic, or electric actuators.
#11. Why calibration of the instrument is important?
Ans: It gives the opportunity to check the instrument against a known standard & it also allows you to adjust the output of the instrument.
#12. What are the process Variables?
Ans: Flow, Pressure, Temperature & Level
#13. How to identify an orifice in the pipeline?
Ans: An orifice tab is welded on the orifice plate which gives indication that the orifice plate is in the pipeline.
#14. What is the purpose of the orifice tab?
Ans:
- Indication of an orifice plate in a line
- The orifice diameter is marked on it
- The material of the orifice plate
- The tag no of the orifice plate
- The mark is the inlet of an orifice
#15. What is the purpose of the Condensation port?
Ans:
- It is used to ensure constant pressure on the LP side
- The condensation of steam in the impulse lines does not impair the ability to accurately sense DP.
#16. What is the purpose of Square Root Extractor?
Ans: It takes the square root of the signal from the FT & converts a corresponding linear flow signal.
#17. What is the working principle of Magnetic Flowmeter?
Ans: Mag FM is a velocity-based flowmeter. It measures volumetric FR or liquids. It has two exciting coils that generate a constant magnetic field. Liquid flowing through the pipe acts as a conductor.
#18. If an operator tells you that the flow indication is more, how would you start checking?
Ans:
- Flush both impulse lines
- If still the indication is more then check the L.P side for choke
- If there is no choke on both sides then check the leak on the L.P side
- If still problem, Calibrate the transmitter
#19. What is Absolute Pressure?
Ans: AP is the total pressure present in the system.
#20. What is Vacuum Pressure?
Ans: Pressure below atmospheric pressure is known as Vacuum pressure.
