Abstract
A differential pressure transmitter is disclosed, which comprises a body for housing a high-pressure sensor and a low-pressure sensor, a plurality of high-pressure process connectors formed in said body and fluidly coupled to said high-pressure sensor for transmitting a first pressure of a process fluid to said high-pressure sensor, each of said high-pressure process connectors comprising a conduit having an opening for receiving the process fluid, a plurality of low-pressure process connectors formed in said body and fluidly coupled to said low-pressure sensor for transmitting a second pressure of a process fluid to said low-pressure sensor, each of said low-pressure process connectors comprising a conduit having an opening for receiving the process fluid, wherein said second pressure is equal to or less than said first pressure, wherein said openings of the high-pressure connectors are spaced relative to said openings of the low-pressure connectors to allow a plurality of pair-wise connections to the process fluid.
