Overview

Principle of Operation
Single Probe
Microwave pulses are transmitted along a cable or probe to the product being measured. At the point where
the wave meets the product surface it is reflected by the product. The unit automatically calculates the
distance to the pulse reflection using time of flight & time expansion. The intensity of the reflection depends
on the dielectric constant of the product. The instrument measures the time between emission and reception
of the signal which is proportional to the distance.
Dual Probe
The unique patented HAWK Dual probe solution uses specially developed signal mapping techniques.
The combination of HAWK’s hardware and software give an accurate and consistent output for interfaces
level measurement.
Function
The HAWK range of Guided Radar products are ideal
for the measurement of liquids, sludge, powders and
granules to a range of 18m 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.

Minimum Clearance
Typically high dielectric materials (such as liquids) provide a good return signal.
Low dielectric materials (such as plastics and powders) require higher levels of sensitivity to measure. Failure
to adhere to mounting requirements can create a false signal reflection which will exhibit as high level lock-
ups either from the distance of the interference of a multiple of the distance of the interference.
Take into account the possibility of cable sway encroaching on the minimum clearance requirements.

Forces On The Probe

Centurion Guided Radar
Probe Type Tensile Force
A04 (4mm flexible cable @ 20ºC) 5kN
A08 (8mm flexible cable @ 20ºC) 19kN
Probe Type Lateral Force
B08 (8mm rigid probe @ 20ºC) 2kN
C35 (Coaxial Probe 1 @ 20ºC) 4kN
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 (8mm or 4mm) 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 minimised by following the installation guidelines and Placement Requirements.
Powering The Unit For The First Time

Setup Procedure
Centurion Guided Radar
13
Procedure A: Running Digitize while material is touching the probe
This procedure uses automatic procedure for sensitivity adjustment & mapping to calibrate the system based
on the dielectric of the material touching the probe element and the mounting conditions.
This is the recommended calibration procedure for fastest and most accurate unit setup.
•Digitize is located in the Advanced menu.
3. Sensitivity Calibration
• Procedure A: Running Digitize while material is touching the probe
• Procedure B: Using dielectric pre-sets
• Procedure C: Manual Sensitivity Adjustment
Procedure B: Manual Sensitivity Adjustment
This procedure is an advanced method for calibrating the sensitivity of the system. This involves manually
adjusting the sensitivity until the unit is measuring the length of the sensing element or to the depth of material
touching the sensing element.
• The ‘Sensitivity’ parameter is located in ‘Adv Setup’
• You can press ‘CAL’ to fire test pulses. After each pulse the unit will return the signal strength and distance
(depth) of the echo. You should aim for a signal strength of 2-2.5V. This may not be achievable with low
dielectric materials.

False Echo Elimination
Before conducting these steps it is recommended to perform Setup Procedure: Sensitivity Adjustment
Procedure A and ensure mounting requirements are met. Some of the procedures below are performed
automatically by the routine.
1a. Sourcing false echo distance (high level lock)
While the unit is operating and locked onto a false echo you can scroll through diagnostics using the arrow
keys on the keypad. The top line of the display will change but the bottom line will continue to indicate the
standard display mode measurement (such as Space or Material%)
Press the UP arrow until the ‘E:’ diagnostic is displayed. This indicates the depth of the false reading.
1b. Identify signal size of false echo
Press the UP arrow again until the ‘S:’ diagnostic is displayed on the top line. This indicates the signal size of
the echo the unit is measuring (this will be between 0.4V and 2.5V).
2. Eliminating false echo
There are three primary methods of echo elimination.
2-1. Cal Mount:
• If you cannot perform Sensitivity Adjustment Procedure A you can manually perform part of this
procedure via ‘Cal Mount’ in ‘Adv Setup’. You will be prompted to enter the ‘Cal Start’ and ‘Cal End’
distance. You should enter a distance safely closer and deeper than the false echo. You should not enter a
value longer than the probe.
• If the material in the vessel is touching the probe ensure the ‘Cal Mount’ does not pass this depth. The
parameter ‘CalSnstvty’ in ‘Adv Setup’ can be used to increase or decrease the uniform sensitivity of the ‘
Cal Mount’ span.
• After the Cal Mount is complete press RUN several times to return to unit operation. The unit will then begin
to scan deeper down the length of the cable to find the next valid echo.

2-2. Reduce Sensitivity:
• Enter the ‘Adv Setup’ menu and scroll until you see ‘Sensitivity’ parameter.
• Press CAL to edit. Use the DOWN arrow to reduce this value.
• Pressing CAL will fire a test pulse and return the diagnostic data of the Signal size and E: distance.
Fire several test pulses for a good sample size.
• Reduce this value until the unit is no longer displaying the false echo while firing test pulses.
• Press RUN to save and RUN again to return the unit to operating mode.
• The unit will then begin to scan deeper down the length of the cable to find the next valid echo.
.
In Fig 1 you can see at 90% Sensitivity both false echoes and the correct level are considered valid targets by
the unit. At 50% Sensitivity the only echo the unit will see is the correct level
3. Blanking & Span adjustment
• If the previous steps are unable to solve a high level lock up there will be a significant signal interference.
Visually examine within the vessel for any objects near or touching the sensing element.
• Extend Blanking beyond the depth of the false echo and adjust High level so it is not within the blanked
distance.
• Perform a 15 second power cycle, the unit will re-scan for the closest signal which beyond the Blanking
distance.
• Attempt to perform Setup Procedure A, B or C if the unit does not locate the correct distance with the false
echoes blanked out.

Unit is reading deeper than actual level
This may occur in low dielectric applications where the cable weight returns a stronger echo than the
measured material.
If you have used any other parameters such as ‘Cal Mount’ perform a Probe Reset.
Increase Sensitivity:
• Enter the ‘Adv Setup’ menu and scroll until you see ‘Sensitivity’ parameter.
• Press CAL to edit. Use the UP arrow to increase this value.
• Pressing CAL will fire a test pulse and return the diagnostic data of the Signal size and E: distance.
• Fire several test pulses for a good sample size.
• Increase this value until the unit is returning a strong (2-2.5V) Signal size from the false echo.
• Press RUN to save and RUN again to return the unit to operating mode.
• Perform a 15 second power cycle - when the unit re-starts it will begin a new scan over the entire probe to
find the closest echo which passes the Threshold value.
Unit is measuring deeper than the length of the cable
• Press CAL and enter Unlock Code 196 and press CAL.
• Scroll through the main menus to locate ‘Factor yTDR’ menu.
• Press CAL to enter this menu.
• Scroll down to locate the ‘EmptDist’ parameter.
• This should be the length of the cable by factory default. If not, reduce this value to the correct length with a
small additional margin (+250mm/12”). DO NOT ADJUST ANY OTHER PARAMETERS IN THIS MENU.
• Perform a 15 second power cycle - when the unit re-starts it will begin a new scan over the entire probe to
find the closest echo which passes the Threshold value.
