Thermistors,Thermal Sensors

The thermistor is a kind of thermal sensor, making use of a property that changes a resistance value with a change in temperature. There are various kinds of sensors from a thermistor that has a steep temperature characteristic to a platinum thin film thermal sensor that has a stable linearity up to a high temperature. Please select optional ones according to your applications.
