Milltronics ILE-37 S e nsing Head

The Milltronics ILE-37 sensing head is an out-of-process sensing element for A, E, V, and C series solids flowmeters. It 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. A viscous fluid damper prevents oscillation of the mechanism and provides mechanical damping of pulsating material flow.

The ILE-37 sensing head is used with Milltronics E-40 (general purpose), C-40 (coal scale), A-40 (aerated gravity conveyor), and V-40 (vertical material drop) dry solids flowmeters.

Calibration

A Test Weight is a calibration reference used to simulate a material impact force (test rate) on the flowmeter sensing plate during the integrato 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, calculate:

Test Rate (TPH) = Test Weight (grams)

651 grams/TPH

Alternatively, to determine the test weight required for a specific test rate, calculate:

Test Weight = 65

e.g. If the test weight used with an E-40 flowmeter is 500 grams:

Test Rate = 500 grams

Note: Use metric tons per hour (t/h) or short tons per hour (STPH) as applicable for

TPH.

grams/TPH x Test Rate (in TPH)

65 grams/TPH

= 7.65 TPH

LVDT Output

Zero Adjustment (if required)

1. Connect a voltmeter across the LVDT green and yellow (or yellow and white; hazardous LVDT) wires.

2. With no load applied to the sensing plate, observe the V AC reading on the voltmeter.

If the LVDT output is 0.10 ± 0.05 V AC, 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 ± 0.05 V AC 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 steadily increase until a level of 0.75 to 1.0 V AC is achieved.

2. Gently push the sensing head moving beam to the left. The LVDT output should steadily decrease until zero is reached and then start increasing again to 0.015 to

0.5 V AC.

3. Ensure the LVDT output always returns to 0.10 ± 0.05 V AC, (to the right 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. Check to ensure that the LVDT output does not change by more than 0.01 V AC.

Note:

• If the change is greater than 0.01 V AC, adjust the sensing head level, (refer to “Installation” on page 4) until the change with and without the test weight on the sensing plate is less than 0.01 V AC.

• Remove the test weight and readjust the LVDT Output Zero, if necessary. If the level test is performed after the integrator has been calibrated, a new integrator Zero and Span calibration, Span Adjust, and Factoring, should be performed.

Refer to the Integrator instruction manual for Integrator Calibration instructions.

Zero Calibration

Refer to the Integrator instruction manual for Zero Calibration instructions.

Span Calibration

After a successful zero calibration, apply the test weight for the span calibration:

1. Attach one end of a string (monofilament fishing line or fine flexible cable) to the test weight.

2. Route the other end of the string over the calibration pulley.

3. Attach the free end of the string to the string fixing bolt. Ensure the string rests in the groove of the bolt.

Note:

• Ensure there is no material flow during zero and span calibrations

• Ensure the test weight is suspended free of any obstructions.

• Accurate calibration is not assured until material tests and a manual span adjustment have been performed, as outlined in the Integrator instruction manual.

Page 17

Range Springs

The range spring establishes the range of sensing head moving beam travel for a given range of material flow. This spring is installed in the flowmeter sensing head at the factory. The spring is selected 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 from the value of the LVDT output, as measured between the LVDT green and yellow wires (or yellow and white wires in the case of a hazardous-rated LVDT unit).

With the 2.5 V AC, 2.9 kHz LVDT excitation supplied:

• 0.75 mm of moving beam movement = 0.188 V AC output

• 2.40 mm of moving beam movement = 0.600 V AC output

Should the design rate of the flowmeter application change, it may be necessary to select and install another range spring to obtain the optimum moving beam travel (LVDT output) range.

Range Spring Removal

1. Loosen the range spring locknut.

2. Remove the range spring mounting bolt and three flange mounting bolts.

3. 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 three flange mounting bolts.

3. With the moving beam in the static zero position, thread the range spring until the base just touches the static beam and then turn one complete revolution more.

4. Install the range spring mounting bolt and tighten the range spring locknut.

Flowmeter Recalibration

After you have removed and replaced the range spring, recalibrate the flowmeter and integrator. (See the Integrator manual, CALIBRATION section, for details.)

1. Perform the LVDT output zero procedure.

2. Perform an integrator zero and span calibration.

3. Perform a span Adjust and factoring as required.

Page 14 Milltronics ILE-37 – INSTRUCTION MANUAL 7ML19985CW01

Non-linear operation Refer to LINEARITY.

Page 19

Linearity

To test linearity, at least three test weights are used. Each test 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-40 Flowmeter design rate of 12 TPH, the following three test weights could be used:

• 780 g (1.72 lb) = 100% Design Rate = 12.0 TPH

• 585 g (1.29 lb) = 75% Design Rate = 9.0 TPH

• 390 g (0.86 lb) = 50% Design Rate = 6.0 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 nut

• at 150% design rate, the LVDT output does not exceed 1.0 V AC.

• 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 - 100% 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 you are 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.

Electronic linearization should not be used to correct non-linear test weight results.
