ABSTRACT:
A pressure sensor includes a pressure sensitive element and associated integrated circuitry on a common silicon chip. Fusible links in a conditioning network of the integrated circuit are opened by electrical pulses applied to pinouts that are accessible for probing in a trough in the support housing that is exposed during the testing and adjusting phase, but is sealed off by the cover in the final assembly so that the pinouts are no longer accessible.
