Advantages

Disadvantages

Thermocouple

Voltage resistance

Simplicity, durability, low cost

Low voltage signal required reference, less sensitive, and least stable

RTD

Resistance

Accurate, stable, linear

Self heating, Low output signal, fragile, low absolute, resistance, required current source

Thermistor

Resistance

Fast response

High O/P, 20 wire ohms than thermocouple

Non linear

Limited temperature range

Liquid crystal sensor

Color change

Durable,

Resistance sensitive

Limited temperature range
