A linear ntc thermal sensor is a negative temperature coefficient thermal element that outputs by linearization. In fact, it is a linear temperature, that is, a voltage conversion element. Under the condition of working current, the voltage value of the element will change with the temperature. Linear change, which will also achieve a non-electrical to electric linear conversion.

         Generally, the main feature of this ntc thermal sensor is that the relationship between temperature and voltage is a straight line within the operating temperature range. This does not require related linearization for the design of the secondary development temperature measurement and temperature control circuit. Design of temperature measurement and temperature control circuit, which can simplify the design and debugging of the instrument.          The general temperature measurement range is between plus and minus two Baidu, but considering the actual needs, so such a wide temperature range is generally not needed, so basically three different sections are specified to adapt to different package designs The choice of extension cables is also different. For temperature compensation dedicated linear thermal element.
