Non-Conductive Medias
⻬ Wide Range of Applications/Industries
(i.e. Water, Oils, Corrosives, etc.)
The LVCN4300 Series level switches are flexible,
as well as cost effective, level solutions for a great
variety of applications. Rods can be encased in
PTFE tubing as an option.
The wide range of applications for RF level
measurement switches incllude liquids and paste.
To cater to all applications, OMEGA’s capacitance
probes are offered with different designs and features.
Housings must also be compatible with the
requirements for hazardous, wash-down,
wet, and/or dusty environments. Explosion-proof
environments may require the housing to be certified.
In addition, the active probe might need to be
intrinsically safe or have an intrinsic safety barrier.
The LVCN4300 series point level switch probe
works as a remote probe and is compatible with
the LVCN400 series relay. This combination allows
the electrode to be used in temperatures up to
177°C (350°F). The LVCN4300 is a very compact
316 SS switch.
