EXHAUST SENSOR HEATER CIRCUIT FOR NON-CALIBRATED REPLACEMENT IN EXISTING APPLICATIONS

摘要

A planar device includes a heating circuit that is disposed between ceramic layers in a planar device and co-fired with the ceramic. The heating circuit material and geometry are controlled so as to provide a targeted resistance characteristic as a function of temperature that allows interchangeability in an engine management system that was designed for a heater circuit based on a material system that cannot be co-fired with the planar device.
