Monitoring

OMEGA’s PX437, PX438, and
PX439 Series submersible water level
transmitters are designed to meet the
rigorous environments of applications
such as well monitoring, pump tests,
lift stations, chemical tank levels,
groundwater and surface water
measurement, and process control.
They provide repeatable, precision
depth measurements under the
most adverse conditions.These
transmitters use a silicon pressure
cell fitted into a stainless steel housing
with an integral welded 316 stainless
steel barrier diaphragm. The nose
cap is made of Delrin®.

The supplied calibration sheet
specifies input and output data that
reflects the unit’s static accuracy
and thermal characteristics.

Each transmitter is shipped with a
trap that prevents moisture from
entering the vent tube. Replacement
moisture traps are available as
accessory items.
