Auto Oxygen Sensor Mondeo S7F-9F472-AB for Ford 

Auto Oxygen Sensor Mondeo S7F-9F472-AB for Ford Production introduction:   The heating elements of oxygen sensors are typically controlled in an open loop with a pulse width modulated voltage, though modern sensors often have heating elements that are controlled in a closed loop. The measured resistance of the ceramic indicates the temperature, so the energy needed to hold the temperature constant can be readily calculated. Closed loop control assures a more reliable signal in different environmental conditions.  Oxygen sensor is the standard configuration of automobile. It uses ceramic sensitive element to measure the oxygen potential in the exhaust pipe of automobile, and calculates the corresponding oxygen concentration according to the principle of chemical balance, so as to monitor and control the combustion air-fuel ratio, so as to ensure the product quality and exhaust emision up to the standard.
