Temperature Sensor - Non-contact temperature measurement advantages: measurement limit the degree of temperature sensing element is not limited, so there is no restriction on the maximum temperature can be measured in principle. For temperatures above 1800 ℃ temperature sensor applications, mainly in non-contact temperature measurement. With the development of infrared technology, radiation thermometry gradually extended from the visible to the infrared temperature sensor wholesale, until the room temperature below 700 ℃ have adopted, and high resolution. Thermistor as well as its own measurement techniques. Thermistor is small advantage, it can quickly stabilize and will not cause heat load. However, very strong and therefore, a large current will cause self-heating. Because the thermistor is a resistive device, any current source will be in on it because of power caused by heat. Power is equal to the square of the current and the resistance of the product. Therefore, to use a small current source. If the thermistor is exposed to heat, and will result in permanent damage. Through the introduction of two temperature instrument, we want to work and study help.
