www.analog.comResistance Temperature Devices (RTDs) are accurate, but require excitation current and are generally used in bridge circuits. Thermistors have the most sensitivity but are the most non-linear. However, they are popular in portable applications such as measurement of battery temperature and other critical temperatures in a system.

Technical Explanation for Temperature Controllers
www.ia.omron.comDevices that can handle sensor signals other than for temperature, such as humidity, pressure, and flow rate , are called Controllers. Electron ic controllers are specificall y called Digital Controllers. Temperature Control Temperature Controllers control temperature so that the process value will be the same as the set point, but the
