CIRCUIT ARRANGEMENT FOR EVALUATING A SIGNAL PRODUCED BY A SEMICONDUCTOR SENSOR |
摘要 |
A circuit for the evaluation of a signal produced by a semiconductor gas sensor provides a reliable control for manipulating a recirculated air valve in motor vehicles and their air-conditioning systems and includes a voltage divider connected with an integrator having a time constant bigger than time needed for reaching a peak of noxious gases outside of the motor vehicle. |
