This graph show how each NTC thermistor sensor is reacting to the external, ambient temperature rise that is occurring. The green curve represents the external temperature ramp up (V3). The two NTC thermistor sensors detect the relative threshold of the external temperature rate of rise. The red curve represents the response of the exposed NTC sensor (Texp) and the blue curve represents the response of protected NTC sensor (tref) which is much slower.
