초록

A sensor apparatus is provided for transmitting electrical pulses from a signal line into and out of a vessel to measure a process variable. The sensor apparatus has a mounting section, at least one dielectric insert, a conductive transitioning pin, a metallic insert, a probe element, and an electrical connector to the signal line. The mounting section is configured to be coupled to the vessel and includes a central aperture with a first tapered surface. The dielectric insert has a second and third tapered surface. The second tapered surface is configure...
