Patent ID: 7698950

Claim:
An absolute pressure transducer for outputting a signal indicative of an absolute pressure of a process to be measured, the transducer comprising: a pressure-tight pressure port connectable to said process; a housing accommodating a first pressure sensor, a second pressure sensor and a common circuit board; said first pressure sensor analogically detecting a difference between a pressure of said process and an ambient pressure inside the housing; said second pressure sensor detecting said ambient pressure in said housing as an absolute pressure; and said common circuit board being connected to both said first pressure sensor and said second pressure sensor and having a data processing unit, wherein said second pressure sensor is adapted to issue an electronic signal indicative of said ambient pressure, and said circuit board converts said analogically detected pressure difference into a digital signal, determines the absolute pressure of said process based on the signals from said first and second pressure sensors and outputs a signal indicative of the absolute pressure of said process.
