Low pressure sensing in medical applications

Silicon sensing elements remain one of the least expensive technologies for sensing and as a result this dual sensing element can be offered for a small cost differential to that of traditional single element silicon sensors. A typical 4-inch silicon wafer yields over 1000 die at a cost, which is typically less than $0.50 each. The use of two sensing elements in low cost packaging makes dynamically compensated sensors a cost-effective solution. The miniature printed circuit board mountable sensor shown in a figure is priced at under $15 in OEM quantities
