MULTILAYER GAS SENSOR HAVING DUAL HEATING ZONES

摘要

A gas sensor (10) for detecting NOx is provided. The gas sensor may have a plurality of substrate members (30, 40, 50, 70, 80), a first sensing electrode (32), and a second sensing electrode (82). The gas sensor may also have a first heater element (52) associated with the first sensing electrode and being located on a first side of one of the plurality of substrate members (50), and a second heater element (54) associated with the second sensing electrode and being located on a second opposing side of the one of the plurality of substrate members.
