Centurion Guided Radar
Overview
3
Principle of Operation
Guided-wave technology sends the radar pulse down a probe to measure liquids & liquid interface (low to
high dielectric layers).
The pulse hits the surface of the first layer (low dielectric layer) and is reflected back up the probe. The pulse
continues to the second interface (high dielectric layer) and is then reflected back to the probe. The transit
time for both layers is translated into a distance using time of fight and time expansion.
Function
The HAWK range of Guided Radar products are ideal
for the measurement of liquids, sludge, powders
and granules to a range of 18.5m for level and
interface. This technology is not affected by pressure,
temperature, viscosity, vacuum, foam, dust, changes
in dielectric constant or coating of the probe.

A non conductive vessel will require a conductive metal strip or equivalent connected to the metal flange or
thread and running along side the vessel for at least the Probe insertion length. A conductive metal sheet
(min 0.5m (8") should also be mounted on the roof and be in contact with metal thread or flange.
If a seal / gasket is used between the flange and the vessel ensure non coated / painted bolts are used to
create ground reference with vessel.

Adjusting Probe Length
Rigid Probes
Cut rigid probes to appropriate length. After adjustment, you must change the 'ProbeLength' Parameter in
'Advanced' menu to represent the new length (password 222).
Flexible Probes
(a) Mark the point at which the flexible cable enters the cable weight.
(b) Release the cable weight grub screws with hex key.
(c) Measure and note the length of cable concealed within cable weight.
(d) Cut cable noting the length of cable must include the concealed length above.
(e) Re-insert the cable into the weight and tighten grub screws to tightening Torque of 20Nm.
Use loctite 243 or equivalent on grub screws to secure once completed.
(f) Adjust ProbeCalibr Parameter in 'Advanced' menu to represent new length (password 222).

Rotating non Ex d Rated Enclosures (page 1 of 2)
The gland which couples the sensing probe to the enclosure provides a critical sealing function for the
enclosure. Internal wires are passed through this gland and the high integrity seal. This gland incorporates a
Union Joint which is designed to rotate.
However, this rotation is limited to one-time adjustment of Display orientation after installation on site, as
shown below:
ONLY one 36mm spanner applied to the Hex of Union Joint to rotate enclosure to desired orientation as
allowed. DO NOT hold the enclosure during this procedure.
Rotation beyond these strict limits can damage the internal cables
Ensure Enclosure follows the spanner rotation and assembly integrity is not compromised

B06 / K06 (6mm rigid probe @ 20ºC) 3 Nm
B08 / K08 (8mm rigid probe @ 20ºC) 8 Nm
Forces On The Probe
Tensile forces are heavily dependent on the viscosity and abrasive characteristics of the product in the vessel.
Ensure tensile loading is appropriate for the selected cable as well as the silo cover and mounting structure.
In critical cases it is better to select the larger flexible cable (8mm).
Lateral forces can exist due to movement and gradual flow of the product in the vessel, particularly with
powder and granular materials.
These forces can cause stress and strain on the probe, as well as the process fitting and mounting hardware.
Ensure that lateral forces are minimized by following the installation guidelines and Placement Requirements.

Digitize Function
The 'Digitize' function is an automatic setup routine to create a digital map of false echoes generated by
problems such as non-recommended mounting.
The function should be performed after physical installation to the application.
When executing the function the unit scans for the Upper Material Level. You will be prompted with a distance
value (measured from base of connection thread / flange down). This must be either be the Upper Material
Level if material is present or the end of probe if the vessel is empty. If the correct level is not detected, see
'Troubleshooting' 'Digitize displays incorrect distance'.
Ensure the value is not greater (further away) than the distance to the material level.
For best results follow this routine:
1) Ensure the unit is mounted according to mounting specifications and requirements.
2) Ensure the material to be measured (If this is an Interface application, the Upper Layer) is in contact with
the actively measured part of the probe.
3) Select Dielectric pre-set value of most similar to material to be measured (If this is an Interface application,
it must be the Upper Layer).
4) Run Digitize routine. Confirm displayed distance is the correct material level (If this is an Interface
application, it must be the Upper Layer.
