Abstract
A combined pressure and temperature sensing device includes a sensor port geometry that provides improved contact between a fluid media being measured and a thermistor cavity of the sensor port. The increased contact area provides improved response time and accuracy compared to previously known integrated pressure-temperature sensors. A temperature sensor element is offset from a pressure sensor element relative to a central axis of the temperature-pressure sensor body/package to facilitate substantially increasing a pressures sensor cavity volume without increasing the overall sensor port diameter. A wire-bondable thermistor support portion facilitates high volume automated production line. The temperature sensing element may be resistance welded to the thermistor support portion in a parallel manufacturing process.
