• Analog Sensor

• Digital Sensor

• Proximity Sensor

In a capacitive proximity sensor, what physical principle enables the detection of nearby objects?

• Electromagnetic induction

• Change in capacitance

• Magnetic attraction

• Optical reflection

How does a solenoid valve control the flow of liquid or gas?

• By adjusting the pressure of the fluid

• Using an electromagnetic plunger to open or close the valve

• By detecting the temperature of the fluid

• Through the oscillation of the electromagnetic field

Which type of proximity sensor is suitable for detecting metallic objects?

• Capacitive Proximity Sensor

• Inductive Proximity Sensor

• Photoelectric Sensor

• Reed Switch

When a through-beam photo-optic sensor detects an object, what happens to the emitted light beam?

• It reflects off the object

• It becomes diffused Sensor

• The beam is broken or blocked

• It oscillates at a higher frequency

Which sensor would be best for measuring fluid pressure in a tank?

Default

• Inductive Proximity Sensor

• Analog Sensor

• Digital Sensor

• Smart Sensor

How does a retro-reflective photo-optic sensor detect objects?

• By using a beam that reflects directly off the object

• Through a beam bounced off a reflector

• By measuring the distance to an object using laser light

• Through diffusion of light waves in all directions

What is the advantage of using smart sensors in industrial applications?

• They are less expensive than analog sensors

• Simplify the system by integrating complex processing capabilities

• They do not require external power supplies

• They work only with digital signals
