Abstract:
A sensor for detecting the pressure and temperature of a media, comprising:an outer housing;a tubular insert located inside the outer housing, said tubular insert has a first narrow end and a second widened end;a pressure sensor with a first pressure sensing surface and a second non-pressure sensing surface, said first pressure sensing surface mounted to the first end of the tubular insert for measuring the pressure of the media flowing into the second end;temperature sensing means being in thermal contact with said second non-pressure sensing surface of said pressure sensor for sensing temperature of the media;storage means communicating with said pressure sensor and temperature sensing means for storing a range of temperature offset information preestablished from said pressure sensor through a range of different pressure sensor temperatures; anda microcontroller in communication with the pressure sensor, the temperature sensing means and said storage means for reading the measured pressure and temperature and said storage means and outputting a temperature corrected pressure digital signal.
