Abstract
A pressure transmitter comprises a first housing having a first and second diaphragm for receiving a first and second process fluid under a first and second pressure, respectively. The first and second diaphragm is deflected in response to the first and second pressure of the process fluid. A second housing includes a printed wire board. A first and second capillary tube is included, the first capillary tube being operatively coupled to the first diaphragm and the second capillary tube being operatively coupled to the second diaphragm, each corresponding capillary tube having an internal fluid therein. A sensor package, having a sensor element, is mounted internally within the second housing, and is coupled to the first and second capillary tubes such that the sensor element provides a first signal which is coupled to electrical circuit components mounted on the printed wire board to output a signal representative of the differential pressure of the process fluid.
