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 temperature sensor technology, radiation thermometry gradually extended from the visible to the infrared, below 700 ℃ until room temperature has been adopted, and high resolution. Thermistor measurements in two lines is the absolute temperature, better precision temperature sensor models, but even more expensive than the heat temperature sensor manufacturers, can be measured temperature range is less than a thermocouple. A conventional thermistor resistance at 25 ℃ is 5kΩ, per 1 ℃ resistance change caused by a temperature change of 200Ω. Note 10Ω lead resistance caused only negligible 0.05 ℃ error. It is ideal for current control applications require fast and sensitive temperature measurement. Small size for applications requiring space is beneficial, but must be taken to prevent self-heating errors.
