ABSTRACT:
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 configured to engage the first tapered surface of the mounting section to prevent movement of the dielectric insert in a direction away from the mounting section. The conductive transitioning pin has a fourth tapered surface configured to engage the third tapered surface of the dielectric insert. The metallic insert is located above the transitioning pin and the dielectric insert, and is coupled to the mounting section to secure the dielectric insert within the mounting section. The conductive probe element is coupled to the transitioning pin and extends downwardly through the dielectric insert and into the vessel. The electrical connector is coupled to the transitioning pin and is configured to couple the signal line to the probe element through the transitioning pin.
