A New Temperature Sensor 790145

A new technology for temperature sensors has been developed. The sensors are extremely rugged, capable of withstanding the most rigorous environments, and they are expected to result in very inexpensive product manufacture.
This paper discusses the evolution of the design of metal core hybrid substrates and the principles of construction of a temperature sensor as a hybrid circuit on a metal core substrate. Sensor performance characteristics and cost are also explored.
A discussion of the linearity of voltage response to temperature is included, and data are presented on the performance of the sensor in various environments.
The paper concludes that the new sensor is suitable for operation in all environments found in automotive applications, and that its range is sufficient to accommodate all of the control functions currently found in the literature.
