摘要: A sensor apparatus is provided for transmitting electrical pulses from a signal line (115) into vessel (14, 204, 304, 404) to measure process parameter. In one embodiment the (10) includes lower flange (32) configured be coupled (14) and an upper (68) (32). Both flanges (32, 68) are formed include central aperture (38, 80) defined by tapered surface (48, 82). The also conductive probe element (36) including head (54) having first second surfaces (58, 60) elongated portion extending away (54). (58) of engage (48) prevent movement in direction toward (82) (68). still further connector (92) (36). Other embodiments dielectric or metallic inserts (224, 322, 314, 418, 454) pins (234, 318, 440) (202, 302, 402). some embodiments, (322, 426) pin (318, has section (340, 448) (302, spring (228) provides upwardly directed biasing force. several (320, 458) other which slidably engages permit 402) while mounting connection.
