The purpose of this paper is to outline some of the approaches to provide an exhaust gas high temperature sensor with wide temperature detection range and fast responsiveness.
Conventional exhaust gas temperature sensors were designed only to detect an overheating catalyst, so they were unable of detecting temperatures below 600°C. Their slow responsiveness prevented them from detecting rapid catalyst temperature changes.
The development of a new thermistor material enabled the sensor to measure a wide temperature range of 300°C to 1000°C. This new sensor provides fast response time (x = 8.7seconds.) as well as durability capability to 1000°C
Applications for this sensor include in catalyst preheating and OBD-II systems.
