Low differential pressure transducer
Abstract:
It is an object of the present invention to provide a pressure transducer having a header wherein the header is comprised of a first section and a second section that are offset from each other. Each first and second section has a flexible diaphragm adapted to receive a first and second pressure, respectively. A central channel connects the diaphragms and a pressure sensor, located within the central channel, communicates with the channel and produces an output equal to the difference between the first and second pressures. The resultant device is a low differential pressure transducer which enables one to bring leads from the sensor out while having diaphragms of substantially the same size and diameter, therefore enabling the diaphragms to exhibit the same back pressure and be equally compliant.
