Introduction

LV4000 ­Capacitive Continuous
Level Measurement Sensor

The LV4000 Series is a capacitance continuous level transmitter with
an integrated electronics module mounted within the housing. This 2
wire loop powered unit provides a 4-20mA output and
measure the level in most industrial applications The LV4000 is
available in 316SS rod and connection or with optional ETFE tubing or
ECTFE coatings (required for conductive or aggressive mediums) on
the rod.
or reference sheath built into the process connection.
calibration is achieved with a zero and span adjustment which works
best when starting with an empty tank to set the zero and then filling it
to set the span.

The wide range of applications for RF analog level measurement
probes (such as liquids, pastes, solids and granules), requires
attention in selecting the correct configuration and installing it in the
proper location.

The LV4000 can also bemade with a secondary reference rod

How it works:

A capacitor consists of the probe’s rod as one plate and the metallic
wall of the vessel (ora secondary reference rod or sheath) as the other
plate. As the medium rises and displaces the empty space within the
vessel, the dielectric constant around the probe changes. This change
is recorded and converted into a 4…20mA output signal which is
proportional to the level within the vessel. By using this principle, the
LV4000 Series can be applied in a wide range of products such as
most liquids, powders,pastes and granular mediums.
