Temperature control device, temperature control method, gas sensor, method for manufacturing a gas sensor and temperature control system for a gas sensor

摘要

Gas sensor having a sensing element portion (71) having a solid electrolyte body and a pair of electrodes disposed on the solid electrolyte body, and a heater (73) for heating the sensing element portion (71). Inherent characteristic information is recorded in a recording section (170) provided on the gas sensor or in a recording section provided separately from the gas sensor. The inherent characteristic information is information that is specific to the sensing element section (71) and that enables a relationship between a change in the temperature of the sensing element section (71) and a change in the internal resistance between the pair of electrodes to be set.
