Abstract
A process variable transmitter configured to sense a process pressure of a process fluid in an industrial process. The transmitter includes a pressure sensor and measurement circuitry carried on a circuit board electrically couples to the pressure sensor and measures the process pressure. At least one via hole is formed in the printed circuit board which is electrically coupled to the measurement circuitry. A slot extends from the via hole to an edge of the circuit board. A wire is soldered to the via hole and electrically connects the via hole to an electrical connection on the pressure sensor to thereby complete an electrical connection between the pressure sensor and the measurement circuitry. A method is also provided.

A process variable transmitter configured to sense a process pressure of a process fluid in an industrial process, comprising:
- a housing;
- a pressure sensor configured to sense an applied pressure and having an electrical characteristic which changes in response to the applied pressure;
- measurement circuitry carried on a circuit board configured to electrically couple to the pressure sensor and measure the process pressure based upon changes in the electrical characteristic of the pressure sensor;
- at least one via hole formed in the printed circuit board which is electrically coupled to the measurement circuitry;
- a slot which extends from the via hole to an edge of the circuit board;
- and
- a wire which is soldered in the via hole and which electrically connects the via hole to an electrical connection on the pressure sensor to thereby complete an electrical connection between the pressure sensor and the measurement circuitry for use in sensing the electrical parameter of the pressure sensor by the measurement circuitry.
