Abstract:
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, the mounting section including a tapered surface adjacent a bottom end of the mounting section;a conductive probe element including a head having a tapered surface, and an elongated conductive portion extending away from the head, the tapered surface of the head being configured to engage the tapered surface of the mounting section to prevent movement of the probe element in a direction toward the mounting section;a dielectric insert located above the head of the conductive probe element;a conical transitioning pin having a lower flange configured to abut the dielectric insert and a threaded member for coupling the pin to the probe element to secure the probe element to the mounting section;a spring located between the dielectric insert and a flange of the mounting section to provide an upwardly directed biasing force to the dielectric insert, the pin, and the probe element; anda high-frequency electrical connector coupled to the conical transitioning pin, the connector being configured to couple the signal line to the probe element.
