Abstract
A pressure sensor integrated onto an electronic circuit substrate. The pressure sensor measures the effect of the ambient air pressure on a characteristic of the pressure sensor that can be translated into a variable pressure measurement. Another embodiment of the pressure sensor is a pressure switch having a set point that can be configured at, or after, the time of installation of the associated circuit substrate.
Claims6
A pressure translator responsive to an ambient pressure, said pressure translator comprising:
- an enclosure having an open end and defining a cavity;
- a diaphragm covering said open end and forming a fluid-tight seal with said enclosure, said diaphragm responsive to an ambient pressure external to said enclosure, said cavity having an internal pressure, the ambient pressure being translated to said internal pressure by a deflection of said diaphragm, said internal pressure having a correlation to the ambient pressure;
- and
- a pressure sensor disposed within said cavity, said pressure sensor being responsive to said internal pressure.
