This set of Flexible Manufacturing System Multiple Choice Questions & Answers (MCQs) focuses on “Advanced Automation”.
1. Which feature protects human workers from reaching the close vicinity of the system?
a) Package Monitoring
b) Storage Monitoring
c) Error Monitoring
d) Safety Monitoring
View Answer
Explanation: In an automated system, in order to protect the human workers from reaching the close vicinity of the system safety monitoring feature is followed. This provides more safety than the conventional safety.
2. Which sensors are used to detect proper functioning of a part in a work holding device?
a) Smoke Sensor
b) Limit Switches
c) LMDB Sensor
d) Photoelectric Sensors
View Answer
Explanation: The sensors which are used to detect proper functioning of a part in a work holding device are known as limit switches. Smoke Sensor, LMDB Sensor and Photoelectric Sensors were not typically used to detect proper functioning of a part in a work holding device.
3. Which sensors are triggered by the interruption of light beam?
a) Pressure Sensor
b) Limit Switches
c) LMDB Sensor
d) Photoelectric Sensors
View Answer
Explanation: The sensors which are triggered by the interruption of light beam are known as photoelectric sensors. This can be used to detect the presence of human interruption in the work cell.
4. Which sensor is used to detect whether the part the hot enough in a forging operation?
a) Pressure Sensor
b) Temperature Sensor
c) LMDB Sensor
d) Photoelectric Sensors
View Answer
Explanation: The sensors which are used to detect whether the part the hot enough in a forging operation are known as temperature sensors. Overheating affects both the mechanical and metallurgical properties of the material.
5. Which of the following sensors are used to detect fire hazards?
a) Pressure Sensor
b) Temperature Sensor
c) LMDB Sensor
d) Smoke Sensors
View Answer
Explanation: The sensors which are used to detect fire hazards are known as temperature sensors. Flame which generally forms during any fire accident is quick enough the smoke sensor which will send signals to the alarm.
6. Conveyors are used for safety monitoring ranging from simple devices to sophisticated devices.
a) False
b) True
View Answer
Explanation: Sensors are used for safety monitoring ranging from simple devices to sophisticated devices. Conveyors are used to transport the materials from the loading station to the unloading station.
7. Which systems are used to perform surveillance of the automated system and its surroundings?
a) LMDB Sensor
b) Pressure Sensor
c) Machine Vision
d) Temperature Sensor
View Answer
Explanation: The systems which are used to perform surveillance of the automated system and its surroundings are known as machine vision systems. It can be used in checking entry to detect the presence of any metal form the worker.
8. Which sensors are used to detect an object when it enters the detection range and boundary of the sensor?
a) LMDB Sensor
b) Proximity Sensor
c) Machine Vision
d) Temperature Sensor
View Answer
Explanation: The sensors which are used to detect an object when it enters the detection range and boundary of the sensor are known as proximity sensors. It is a type of non contact sensor which functions without making contact with the object.
9. What is meant by LVDT in terms of sensors?
a) Lean Velocity Displacement Transducer
b) Linear Variable Displacement Transducer
c) Level Voltage Displacement Transducer
d) Low Voltage Displacement Transducer
View Answer
Explanation: In terms of sensors, the abbreviated form of LVDT is Linear Variable Displacement Transducer. It has good linearity and high sensitivity. Lean Velocity Displacement Transducer, Level Voltage Displacement Transducer and Low Voltage Displacement Transducer were not the literal abbreviations of LVDT in terms of sensors.
10. What is meant by UWB in safety terminology?
a) Ultra Wide Band
b) Unique Width Bar
c) Ultra Width Bar
d) Unique Width Band
View Answer
Explanation: In terms of safety terminology, UWB stands for Ultra Wide Band. It can be used for detecting short range distances and is a wireless technique.
11. Which sensors are used to detect inconsistencies on the surface in a manufacturing process?
a) LMDB Sensor
b) Proximity Sensor
c) Flaw Sensor
d) Temperature Sensor
View Answer
Explanation: The sensors which are used to detect inconsistencies on the surface in a manufacturing process are known as flaw sensors. It identifies defects in the material by using ultra sonic or by using current as its source of energy.
12. Which sensors are used to detect the heights of matter used in a industry?
a) LMDB Sensor
b) Proximity Sensor
c) Flaw Sensor
d) Level Sensor
View Answer
Explanation: The sensors which are used to detect the heights of matter are known as level sensors. It can be used to detect any matter such as solid liquid or gas. A typical application is in storage containers where it is used to send alarms once it reaches the specified level.
