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.
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.

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.
