Temperature sensor, Collection of exercises and questions

What are the different types of temperature sensors?

Type of temperature sensor:

1. PTC
2. NTC
3. PT100
4. LM35
5. Thermocouple

Draw the symbols for PTC and NTC thermistors?

The following is a picture of the PTC and NTC thermistor symbols

Describe the characteristics of PTC and NTC in graphical form?

Characteristics of PTC and NTC

Explain the difference between PTC and NTC?

• PTC if the temperature gets hotter, the resistance will increase.
• When NTC is exposed to hotter temperatures, its resistance decreases.

Learn to assemble sensors
