ILE-61 Sensing Head
Notes:
• The ILE-61 Sensing Head is to be used only in the manner outlined in this
manual, otherwise protection provided by equipment may be impaired.
• This product is intended for use in industrial areas. Operation of this equipment
in a residential area may cause interference to several frequency based
communications.
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.
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.

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