ISOLATOR SYSTEM FOR A PRESSURE TRANSMITTER

摘要

An isolator system 14 for a pressure transmitter 10 includes a port 32 internal to the transmitter 10, a sensor tube 34, and a fill tube 36. The sensor tube 34 is connected to the port 32 to fluidly connect a passageway 28 through a transmitter body 12 to a pressure sensor 16. The sensor tube 34 includes a first end 40 disposed in the port 32. The first end 40 has a first cross-sectional area. The fill tube 36 is internal to the transmitter 10 and connected to the port 32 to fluidly connect to the passageway 28. The fill tube 36 includes a second end 42 disposed in the port 32. The second end 42 of the fill tube 36 has a second cross-sectional area that is less than the first cross-sectional area of the sensor tube 34.
