emperature-sensor

A temperature sensor gathers data concerning the temperature from a source and converts it to a form that can be understood either by an observer or another device. It warns of temperature excursions above the safe operating temperature of the catalytic converter. More-recent catalytic-converter designs are not as susceptible to temperature damage and can withstand sustained temperatures of 900 °C (1,650 °F). Temperature sensors are also used to monitor catalyst functioning: usually two sensors will be fitted, with one before the catalyst and one after to monitor the temperature rise over the catalytic-converter core.
