A sensor apparatus for transmitting electrical pulses from a signal line into and out of a vessel to measure a process variable. The sensor apparatus includes a mounting section configured to be coupled to the vessel, a conductive probe element, a dielectric insert located within the mounting section, a conductive pin coupled to the top end of the probe element, and an electrical connector coupled to the conductive pin. The conductive probe element has a predetermined diameter and is formed to include a section having a reduced diameter adjacent a top en...


[ What is claimed is:] [1.] A sensor apparatus for transmitting electrical pulses from a signal line into and out of a vessel to measure a process variable, the sensor apparatus comprising:a mounting section configured to be coupled to the vessel;a conductive probe element having a predetermined diameter, the probe element being formed to include a section having a reduced diameter adjacent a top end of the probe element and including a tapered section providing transition from the probe element to the reduced diameter section;a dielectric insert located...
