Pressure sensor for determining a pressure of a medium with a medium temperature of up to 200°C.

摘要

A pressure sensor (1) for determining a pressure of a medium with a medium temperature of up to 200°C. comprisinga sensor housing (2)a grease-filled sealing section 14 at the first separating membrane (5) comprising a first pressure chamber (7) is limited in some areas;a pressure measuring cell (9) for determining the to the pressure measuring cell (9) acting pressure, in particular of a differential pressure;inside of the sensor housing (2) a first filled with a transfer fluid channel (8) between the first pressure chamber (7) and the pressure measuring cell (9), for the transmission of a to the first separating membrane (5) of a measuring medium medium pressure acting on the pressure measurement cell (9), runs;the pressure measuring cell (9) from a silicon - is made of material and in that the first channel (8) a length of at least 50 millimeters and a mean diameter of less than 1 mm.n="16"
