What is the meaning of the temperature coefficient "S"?
Temperature coefficient S is defined as the working conditions, the output voltage value of the sensor changes with the ratio of the temperature change is the value of the output voltage change of 1 DegC, The formula:S=△V/△T（mV/℃.
The temperature coefficient is the linear temperature sensor as a physical basis for the temperature measuring element, its effect and thermal is similar like the resistance B-value,the parameters in the entire operating temperature range is the same value, that is -2mV/ DEG C, and various types of sensors is the same value.A traditional thermistor temperature sensor is nothing comparable to this.
What is the significance of linearity?
The linearity is description of the output voltage value of the sensor linearity degree varies with temperature which is actually the output voltage of the sensor in the working temperature range relative to the maximum deviation of the ideal linear fitting. In general, the linearity of the typical value is + 0.5%, obviously the sensor linearity is higher (the smaller the value) and for the design of the instrument is simple, the input level of instrument completely without using linearization.
