ABSTRACT:
An apparatus for testing sensors in a media includes a chamber portion (240) for holding the sensors, tanks (320, 340) for supplying the media to the chamber portion (240) and coupled in parallel to the chamber portion (240), a pressure generator (310) coupled to the tanks (320, 340), and a heat exchanger (323, 324) adjacent to the tanks (320, 340). The media is simultaneously heated to different temperatures and pressurized to different pressures in the tanks (320, 340). Then, the media is delivered from the tanks (320, 340) to the chamber portion (240), and the sensors detect the media at the different temperatures and pressures.
