Gate

What are four types of hall affects sensor actuation

Head on slide by Pendulum Vane

They are two reasons for photocell failure as given in the textbook list them

Humidity Contamination

With a? Thermistor An increase in temperature causes the resistance of the thermistor to increase

PTC

Which of the following is not a type of proximity sensor

Photoelectric

? Scan is a skinny technique which uses a special lens to filter the admitters beam of light so that it is projected in one plain only

Polarized

? Scan of the scanning technique normally used in high vibration applications

Retroreflective

AC photoelectric are connected in? With a load to be controlled

Series

? Scan is a skinny technique which place is the transmitter and receiver at equal angles from a highly reflective surface

Which sensor is a temperature sensitive resistor who is resistance changes with a change in temperature

Thermistor

A? Is a device constructed by to do similar metals that generate a small current when one end heated

Thermocouple

A? Photo electric control is a photo electric control that energize the output switch when the target is missing (removed from the path of the beam )
