Guided Wave Radar Level Transmitter
The Centurion Guided Radar (CGR) Level Transmitter is ideal
for the measurement of liquids, sludge, powders, and granules
to a range of 38m (124ft) for level and interface measurement.
This award-winning technology is not affected by pressure,
temperature, viscosity, vacuum, foam, dust, changes in dielectric
constant, or coating of the probe. HAWK’s CGR won the
prestigious Chemical Processing 2021 Vaaleer Awards.
HAWK’s CGR is the first and only guided wave radar on the
market to feature Power over Ethernet (PoE) communications.
The advantages of PoE connectivity are secure in-plant and
remote monitoring, as well as remote sensor setup, diagnostics,
and troubleshooting abilities.
Principle of Operation
Guided-wave technology sends the radar pulse down a probe to measure either
liquids, solids, or a low dielectric to high dielectric
Interface level.
The pulse hits the surface and / or Interface and is reflected back up the
probe to the sensor, where the transit time is translated into
a distance using time of fight and time expansion. The amplitude of the
reflection depends on the dielectric constant of the product Centurion Guided Radar.

Power over Ethernet (PoE) Communication
Hawk Measurement (HAWK) created the
industry’s first and only Guided Wave
Radar level transmitter that features Power
over Ethernet (PoE) communications. The
advantages to PoE connectivity are secure
in-plant and remote monitoring, as well
as remote sensor setup, diagnostics and
troubleshooting abilities. The Centurion Guided
Radar (CGR) Level Transmitter is ideal for the
measurement of liquids, sludge, powders and
granules to a range of 38m (124ft) for level and
interface measurement.
If troubleshooting is required, the CGR PoE will
communicate to remote service technicians
for off-site diagnostics, sensor health and reconfiguration, without the need to climb
a tank
or enter the facility. HAWK’s CGR PoE can connect to an online portal, the HawkEye365,
which can monitor multiple tanks
worldwide in real-time. The portal provides accessibility to critical data such as the
ability to view volume, space, material
height, historical trending, alarms and alerts, sensor setup and diagnostics. Plant
level operator screens are customized to the
company’s specifications to include control room level and operations level interface
screens. The graphical user interface will
be common throughout and permissions can be set for different tiers such as plant-level,
finance, or executive level.
