Differential pressure transmitter with intrinsic verification
First Claim
1. A differential pressure transmitter, comprising:
- a body for housing a high-pressure sensor and a low-pressure sensor,a plurality of high-pressure input 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 input process connectors comprising a conduit having an opening for receiving the process fluid independent of any of the other high-pressure input process connectors and transmitting said first pressure of the process fluid to said high-pressure sensor,a plurality of low-pressure input 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 input process connectors comprising a conduit having an opening for receiving the process fluid independent of any of the other low-pressure input process connectors and transmitting said second pressure of the process fluid to said low-pressure sensor, wherein said second pressure is equal to or less than said first pressure,wherein said openings of the high-pressure connectors and the low-pressure connectors are arranged so as to allow a plurality of pair-wise connections of the high-pressure and the low-pressure connectors to the process fluid such that spacing between the high-pressure and the low-pressure connectors of each pair is different than the respective spacing of another pair.

18. A differential pressure transmitter, comprising:
-
a body for housing two pressure sensors, at least two sets of process connectors formed in said body, wherein each set comprises at least two connector, and wherein the connectors of the first set are configured for transmitting pressure of a process fluid to one of said sensors and the connectors of the second set are configured for transmitting pressure of the process fluid to another one of said sensors, each of said process connectors comprising a conduit having an input opening for receiving said process fluid, wherein the process connectors of the first and the second set can be pairwise coupled to said sensors for obtaining a pressure differential of a process fluid as it flows through a conduit fluidly coupled to the transmitter. - View Dependent Claims (19, 20, 21, 22)
