The high-frequency level sensor RFLS–35 is designed for industrial use for limit sensing of the
level of liguid and paste-like media. The high-frequency level sensor may be a direct replacement of
a vibrating level sensor, or of a capacity level sensor in case of more demanding applications. The
media may be electrically conductive or non-conductive with any permittivity. It can be installed in
metalorplastictanks,pipes,llingtanks,sumps,etc.
It is mainly designed for mounting into the wall of a tank or pipe, in which the actual detection of the
level will take place. The sensor works in the high frequency band, enabling reliable detection of
the level of media, and eliminating deposits or foam on the electrode. The sensor suppresses the

The sensor is made from a stainless steel housing at one end terminated by a sensing electrode,
and terminated at the other and by an ending with a status indicator, control elements and electrical
connection.
