ILE-61 Sensing Head

The Milltronics ILE-61 sensing head is an out-of-process sensing element for A, E, and V

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.

The ILE-61 sensing head is used with Milltronics E-300 (general purpose), A-300 (aerated

gravity conveyor), and V-300 (vertical material drop) dry solids flowmeters.

Installation

Sensing Head

1. With the flowmeter housing installed, mount the ILE-61 to a rigid support structure.

2. Remove the ILE-61 fibreglass cover. With the outer gasket in place, bolt the ILE-61 to

the housing.

3. Adjust the sensing head leveling hardware (provided) to establish level in both

horizontal planes.

Sensing Plate

1. Open the flowmeter housing access door.

2. With the sensing head cover removed, remove the taper pin.

3. Insert the sensing plate shaft fully into the sensing head socket.

4. Insert the taper pin (flat side down), from the left side.

5. Tighten the right taper pin nut to lock the sensing plate shaft in place.

6. Tighten the left taper pin nut.

Note: Ensure the sensing head mounting structure is capable of supporting the

dynamic material impact forces as well as the weight of the sensing head.

Note: Ensure the sensing plate shaft is installed with the flat side up.

Viscous Damper

1. Remove the 2 damper cover shipping screws. The damper cover will be held up by a

spring.

2. If necessary, top up the damper (to near overflowing) with the damping fluid

supplied.

3. Store the damper cover shipping screws, remaining damper fluid, and filler bottle for

future use.

Interconnection

Non-Hazardous Unit without LVDT Conditioner Card

* See note below for Encapsulated (Hazardous-rated) LVDT color codes.

Note: The damper must be full and free of air bubbles with the damper cover in

the UP position during flowmeter operation.

Note: Ground shield at Integrator only.

Non-Hazardous Unit with Sensing Head Mounted LVDT

Conditioner Card

• Not applicable to Hazardous-rated units

• LVDT to LVDT Conditioner Card connections are made by Milltronics

*Where separation between the integrator and LVDT conditioner exceeds 150 m (500 ft):

• Remove the jumpers SF 500 terminal 11/12 and 13/14

• Run additional conductors:

- from SF 500 terminal 12 to conditioner terminal block marked“Integrator +EXC”

- from SF 500 terminal 13 to conditioner terminal block marked “Integrator –EXC”

For further connection information on specific LVDTs, consult Siemens Milltronics.

♦Note:

1. Shields are common, but not grounded to chassis. Run cable shields

through SHLD terminals and ground at Integrator only.

2. Ensure that connection between TB 2 and TB 17 is made.
