Electrode Assembly
SITRANS LC 500 electrodes come in a variety of formats to provide the necessary
characteristics for correct mounting, chemical compatibility, temperature and pressure
requirements, and dielectric constant of the medium. The main body of the manual
discusses the standard configuration. Other options, with details, are shown in

Appendix E:
Process Connections
The standard threaded process connection (S-Series) with PFA insulated electrode,
including the active shield, provides good results in all measurement situations within the
temperature, pressure, and corrosive capabilities of the materials and seals. This remains
true over a wide range of dielectric constants in both non-conducting and conducting
materials.

Any standard process connection is available with the SITRANS LC 500, and special
versions can be fabricated to match the mounting and application requirements. A wide
range of threaded and flanged fittings is available. (Contact your local Siemens

Seal Types
The basic internal seal for the SITRANS LC 500 has a conical-shaped, preloaded
pressure/leak resistant construction. Up to three levels of seal protection are
implemented depending on the integrity requirements of the application. A single or
double cone internal seal forms one or two barriers against leaking, and a third flange
face gasket is also available in the D and DD seal construction. The flange face seal also
provides a design with no metal wetted parts if required.
