Pulse Radar Solids Level Transmitter
LR4 6
Application
The intrinsicallty safe 26 GHz. pulse radar transmitter provides
continuous level measurement up to 229.7’ (70m) with a 4-20
mA analog and HART digital signal output, and is configured via
its integral push button display module or HART communicator.
The non-contact solids level sensor is intended for dry solid
media including aggregates, grains, pellets, powders and building
materials. Select this sensor for the most difficult process
conditions with significant to extreme dust, and installation with
an adjustable gimbal flange. For ease of installation, the parabolic
antenna can be unclamped, inserted through the base of a riser,
and reattached to the sensor. Typical applications include silos.
Features
Parabolic antenna delivers high power RF signal strength
Configuration via push button display or HART communicator
Gimbal flange for easy positioning with the angle of repose
LCD displays level in feet or meters with percent of span bar
Optional display mode indicates the echo signal return curve
Rugged 316L stainless steel antenna and process mount
Fail-safe diagnostics with selectable signal fail-safe outputs
Recognition, storage and rejection of false echo signal returns
IP67 stainless enclosure with polycarbonate display window
Antenna Selection
The reflective parabolic antenna
focuses the RF energy to narrow
the beam and increase the signal
strength. The sensor is offered in two
antenna sizes including 8” (196mm)
and 10” (246mm). The larger the
antenna, the narrower the beam and
the stronger the RF signal return.
To select the appropriate antenna
size, consider two variables; The
measured span distance and the
amount of dust within the span.
