Compact Microwave Water-Conductivity Probe With Integral Second Pressure Barrier

摘要

Methods and devices for measuring fluid properties include an electromagnetic sensor. The electromagnetic sensor includes a coaxial probe body having a first integral pressure barrier and a second integral pressure barrier formed from coaxial-feedthrough connector. The first integral pressure barrier and the second integral pressure barrier have a desired characteristic impedance.
