Differential pressure transmitter

An apparatus for measuring a pressure differential between two points as a process variate and simultaneously measuring a high or low static pressure which comprises:

• means for detecting and transmitting said pressure differential;
• a sensor housing detachably coupled to said detecting and transmitting means for converting said pressure differential into an electrical output
• wherein said sensor housing is detachably coupled to the upper surface of said detecting and transmitting means, said sensor housing comprising:
• an outer body containing a first and a second recess;
• a hollow inner concentric cylindrical body contained within said first recess of said outer body forming a first gap path between said first recess and said hollow inner cylindrical body wherein said first gap path contains said noncompressed liquid;
• means for converting said pressure differential into an electrical output contained within said hollow inner cylindrical body forming a second gap path between said converting means and said hollow inner cylindrical body wherein said second gap path contains said noncompressible liquid;
• and
• means for measuring a static pressure differential contained within said second recess of said outer body forming a third gap path between said means for measuring static pressure differential and said second recess wherein said third gap path contains said noncompressible liquid;
• whereby said first and said second gap paths communicate with said first said second sealing circuits of said detecting and transmitting means.
