The Scanlube XDT-US is an optical turbidity meter that measures the clarity of
almost any waterbased lubricant. The Scanlube XDT-US is designed to be
incorporated with your existing proportioner and will continuously measure the
solution and provide a digital readout of the relative clarity. This output is
easily converted to a dilution ratio after the system has been calibrated.
Upon calibration with the lubricant and dilution water the unit will have a
target dilution as well as an upper and lower control limit programmed into the
controller. The target dilution is fixed upon calibration, and the upper and
lower control limits are easily modified by the user. The Scanlube XDT-US is
designed to provide very accurate dilution information with minimal
maintenance and investment.
How it works:
The spacer between the two light sources is chosen so that the target dilution
(for example 1:70) is approximately 2000. This is the midpoint of the
measurement range. In the example below, the target dilution gave a reading of
Upper control limit 1:80 (display value is 1743)
Lower Control limit 1:60 (display value is 2992)
The system will now be constantly measuring the dilution and if it is in between the control limits the readout will be a
green value. If the dilution gets out of control it will give a visual alarm and the display color will turn red. The
Scanlube XDT-US will function with virtually any milky-white emulsion over a wide dilution range. However its
ability to function with clear products (i.e. micro-emulsions) or pigmented lubricants (i.e. graphite) is limited.
The unit requires a standard 110v power supply. The unit should be mounted on a solid wall and close to the material to
be monitored. The probe needs to be positioned in the dilution tank so that the light source is always in the diluted
material. It can be fully immersed in the liquid without damaging the probe. The probe must be suspended in such as
way so as to not place any weight on the fiber optic cable.
How to calibrate:
1: Make three dilutions of the die lube concentrate.
Upper control limit
Lower control limit
2: Measure the target dilution; in this case 1:70. Adjust the distance between the light spacer with the adjustment screw
so that the output is 2000 +/- 300. Clear water will give a reading of about 0000(zero). A typical die lube concentrate
will give a reading of approximately 4000. If the target dilution gives a reading of more than 2300 you need to reduce
the distance between the sensors at the end of the probe.
3: Measure the upper and lower control limit samples and note the values for input into the control unit. Examples from
a typical die lubricant are provided below.
Press "MODE" until you see
Press "SHIFT" until all five-place values are shown. The
“UP” key changes the value of the number and the “SHIFT”
key moves the place. A flashing number indicates that the
“UP” key can change that value. Follow this procedure and
input the value 1943 for the lower control limit in the
Press "MODE" until you see
Use the procedure described above to input the upper control limit, in our example "2992”.Wait 5 seconds and
the unit is ready to use.
