The temperature coefficient S is the ratio of the change in the output voltage value of the sensor to the temperature change under specified operating conditions. That is, the value of the output voltage change of the sensor for every 1 °C change in temperature: S = ΔV / ΔT (mV / ° C).
The temperature coefficient is the physical basis of the linear temperature sensor as a temperature measuring component, and its function is similar to the B value of the thermistor. This parameter is the same value over the entire operating temperature range, ie -2mV/°C, and the sensors of the various models are also the same value, which is unmatched by conventional thermistor temperature sensors.
