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.

In an embodiment, a stepped spring contact may have a first portion, a transition portion, and a second portion. The first portion may include a plurality of windings whose pitch may vary. The second portion may include a plurality of windings that are closely wound. A pitch of the windings contained in the second portion may be, for example, constant. The transition portion may include a winding that may make mechanical and electrical contact with a first electrical conductor (e.g., a pad contained on a printed circuit board (PCB)). The first portion may include a tip. The tip may be, for example, flat shaped or conically shaped. The tip may make electrical contact with a second electrical conductor (e.g., a terminal connector). In operation, the stepped spring contact may provide electrical continuity between the first electrical conductor and the second electrical conductor.
