The Omega® LVTX-10 Series
sensors are low profile designed
ultrasonic transmitter modules
optimized to provide continuous
measurement of fluids, pastes,
or uneven solid bulk materials
in constrained working zones.
Incorporating state-of-the-art
dual-sensor ultrasonic technology
and processing algorithms,
all LVTX-10 sensors provide
accurate measurement for factory
automation, warehouse materials
control, pipe and conveyor belt
blockage, or tank level applications
with non-uniform surfaces.
LVTX-10 sensors include an
advanced diagnostic feature
that will retrieve the ultrasonic
waveform for analysis, and
display it on any computer to aid
users with debugging complex
installations. For solid materials,
surface unevenness is unlikely to
affect maximum ranging capability.
An integrated mounting plate
with pre-formed holes is provided
LVTX-11 shown smaller tha actual size.
for easy installation. All models
are equipped with continuous
temperature compensation to
ensure precise speed of sound
calibration and measurement
accuracy. Other friendly use
features include diagnostic and
monitoring outputs, protection
from over voltage, short circuits,
and reverse polarity. Operating
from 12 to 24 Vdc, all Omega
LVTX-10 sensors provide a linear
output of either 0 to 10 Vdc or
4 to 20 mA, that are proportional
to the measured distance to the
target. The output range is readily
programmable to accommodate
a wide variety of set-up and
application conditions. In addition,
this output voltage can be set to
operate as a digital switch within
zones defined by specified target
set-point distances, enhancing
the sensor’s flexibility for use in
non-routine applications. The
measurement parameters and
outputs are programmed using a
common standard RS485 data link
to ensure set-up uniformity.
LVTX-10 Wiring Diagram
Compatible with Microsoft
Windows® operating systems
using a USB/RS485 or RS232/
RS485 converter, up to 32
sensors can be connected in
parallel onto the same multidrop communication network
using the supplied protocol. This
network also enables users to
remotely program their sensors
and read target distances for
quick integration into control
applications. All LVTX-10 sensors
are adjustable for sampling rate,
averaging measurement, analog
output slope, loss-of-echo timeout, set-point hysteresis (digital
switch mode) and provide a
software sensor transmit trigger.
Omega LVTX-10 sensors provide
versatile distance measurement
for non-uniform liquid or solid
surfaces where mounting
headroom is restricted or a
minimal dead-band is desired
for accurate ranging with an
affordable cost of ownership.
