ILE-61 Sensing Head: Introduction
The Milltronics ILE-61 Sensing Head is used for continuous in-line weighing of powdered
or granular dry bulk solid materials. The material is directed toward the sensing plate.
The horizontal impact force of the material, deflecting the sensing plate, displaces the
core of the sensing head LVDT (linear variable differential transformer). The LVDT output
signal is proportional to material flowrate.

Calibration
LVDT
LVDT
General
A Test Weight is a calibration reference used to simulate a material impact force (Test
Rate) on the flowmeter sensing plate during the integrator Span calibration. The test
weight is also used to perform a test to verify that the flowmeter sensing head is level.
The Test Rate should be 60 to 80% of the system Design Rate.
To determine the Test Rate produced by a specific Test Weight...
Test Rate (TPH) = Test Weight (grams)
45* grams/ TPH
Alternatively, to determine the Test Weight required for a specific Test Rate:
Test Weight (grams) = 45* grams x Test Rate (in TPH)
1 TPH
*Use 60 grams for A-300 flowmeters.
e.g. If the Test Weight used with an E-300 flowmeter is 7000 grams...
Test Rate = 7000 grams
45 grams/TPH
= 155 TPH
Note: Use metric tons per hour (t/h) or short tons per hour (STPH) as applicable for TPH.
LVDT Output
Zero Adjustment
1. Connect a voltmeter across the LVDT green and yellow (or yellow and white) wires.
2. With no load applied to the sensing plate, observe 0.10 Vac on the voltmeter.
Note: If the LVDT output is 0.10 to 0.05 Vac, skip to Span Test, otherwise, proceed as
follows:
a.Loosen the locknut on the LVDT threaded core.
b.Turn the core in/out of the LVDT until 0.10 to 0.05 Vac is obtained.
c.Tighten the locknut, ensuring the measured value is maintained.

Span Test
1. Gently push the sensing head moving beam to the right. The LVDT output should
increase steadily until a level of 0.75 to 1.0 Vac is achieved.
2. Gently push the sensing head moving beam to the left. The LVDT output should
decrease steadily until zero is reached and then increase to 0.25 to 0.50 Vac.
3. Ensure the LVDT output always returns to 0.10 to 0.05 Vac, (on the right hand side of
zero), when pressure on the moving beam is released.
Note: The LVDT core must not contact the inside of the LVDT over the range of core
travel. The actual LVDT core travel during this procedure is less than 3 mm (1/8").

Sensing Head Level Test
1. With the voltmeter still connected to the LVDT output, hang the test weight directly
off the sensing plate.
2. Observe the display value does not change by more than 0.01 Vac.

Note: If the change is greater than 0.01 Vac, adjust the sensing head level until the
change with and without the test weight on the sensing plate is less than 0.01 Vac.
Remove the test weight and readjust the LVDT Output Zero, if necessary. If this
procedure is performed after the integrator is calibrated, a new integrator Zero and
Span calibration, Span Adjust, and Factoring (if required) should be performed.

Page 14 ILE-61 Sensing Head – INSTRUCTION MANUAL 7ML19981CX01
Range Springs
General
The Range Spring establishes the range of sensing head moving beam travel for a given
range of material flow. This spring installed, is selected and positioned according to the
specified Design Rate of the application.
For best operation the range spring should provide 0.75 to 2.4 mm (0.030 to 0.094") of
moving beam travel from the static zero to the Design rate operation position. The moving
beam travel may be inferred by the value of the LVDT green and yellow (or yellow and
white) wires.
With the 2.5 Vac, 2.9 kHz LVDT excitation supplied:
• 0.75 mm of moving beam movement = 0.188 Vac
• 2.40 mm of moving beam movement = 0.600 Vac
Should the Design Rate of the flowmeter application change, it may be necessary to
reposition the original range spring, or select and install another range spring, to obtain
the optimum moving beam travel (LVDT output) range. Moving the range spring to a
location further away from the pivot point leaf spring, increases the maximum flowrate
capacity.
Range Spring Remov al
1. Observe the range spring mounting position. (3 positions are available)
2. Loosen the range spring locknut.
3. Remove the range spring center bolt and 4 flange mounting bolts.
4. Remove the range spring from the range spring assembly.
Range Spring Replacement
1. Install the new range spring in the range spring assembly.
2. Mount the range spring assembly by the 4 flange mounting bolts.
3. With the moving beam in the static zero position, turn the range spring until the base
just touches the beam, and then turn 1 complete revolution more.
4. Install the range spring center bolt and tighten the range spring locknut.
Flowmeter Recalibration
After removing and replacing the range spring, the flowmeter and integrator should be
recalibrated.
1. Perform the LVDT output Zero procedure. Refer to Calibration.
2. Perform an integrator Zero and Span calibration. Refer to the integrator manual,
Calibration.
3. Perform a Span Adjust and Factoring as required. Refer to the integrator manual,
Calibration.

your distributor
Page 16 ILE-61 Sensing Head – INSTRUCTION MANUAL 7ML19981CX01
Linearity
To test linearity, at least 3 test weights are used. Each weight represents a different Test
Rate. Record the integrator Rate display value associated with each test weight applied
to the flowmeter.
If all the recorded display values are accurate, the flowmeter measurement is linear.
e.g. For an E-300 flowmeter Design Rate of 200 TPH, the following three test weights
could be used:
• 9000 g (19.82 lb.) = 100% Design Rate = 200 TPH
• 6750 g (14.87 lb.) = 75% Design Rate = 150 TPH
• 4500 g (9.91 lb.) = 50% Design Rate = 100 TPH
If non-linear results are obtained, ensure:
• at no flow, the moving beam does not rest on the zero stop bolt.
• at 150% Design Rate, the moving beam does not reach the full flow stop bolt.
• at 150% Design Rate, the LVDT output does not exceed 1.0 Vac.
• the damper piston does not touch the damper cylinder wall at any flow rate.
• the LVDT core does not touch the inside of the LVDT at any flow rate.
• the viscous damper fluid is free of large air bubbles and the fluid level is correct.
• the range spring operates in compression from 0 - 150% flow rate.
• the sensing head leaf springs are in good condition.
If the test weight linearity test is successful, yet actual material test results are nonlinear, ensure there is no air circulation in the housing sensing plate area. If there is no
significant air circulation in the flowmeter housing while running material, the material
flow pattern is probably non-linear.
Non-linear material flow patterns can often be corrected by minor modifications to the
material infeed, or upstream piping. Some integrators are equipped with a linearization
function to compensate for non-linear material flow patterns. Stand alone linearizing
devices are also available for this purpose.
Note: Electronic linearization should not be used to correct non-linear test weight
results.
