초록

A sensor apparatus (1) designed for industrial applications is provided for transmitting electrical pulses from a signal line (2) into and out of a vessel to measure a process variable, which has a low outer diameter, preferably of 11/2′ or lower, while providing high mechanical stability and maintaining a high degree of transmission efficiency. It comprises a mounting section (3) configured to be coupled to the vessel, at least two concentric at least partially overlapping dielectric inserts (6, 9, 10, 11, 17) stacked inside one another located inside t...
