Milltronics EASY AIMER 2 User manual

EASY AIMER - 2
The Easy Aimer is an accessory device for aiming Milltronics ultrasonic transducers used in process
material level measurement.
Assembly
1. Feed the transducer cable through
the supplied coupling and conduit.
Then assemble the transducer,
coupling and conduit as shown.
If the transducer diameter is
greater than 148 mm ( 5.8" ),
include the customer mounting
plate. If sealing is required,
include the customer gasket.
2. Feed the conduit through the center
hole of the Easy Aimer until the
conduit is at the desired point within
the Easy Aimer (typically midway).
3. Tighten the conduit gland to
secure the conduit and
transducer assembly in place.
4. Install the supplied locknut
as shown, and complete
the conduit installation.

Application
In solids applications, the transducer is generally mounted so that it is aimed toward the low level draw point.
The sighting block can be rotated through 360° with the transducer angled at 0 to 20° off vertical.
The location of the Easy Aimer should be such that the transducer’s sound path is unobstructed and
away from fill points.
The Easy Aimer is capable of withstanding 100 kPa (1 bar or 15 psi) gauge pressure with proper installation and has a
temperature rating from -40oC to 105oC (-40oF to 220oF).
The Easy Aimer must be mounted to an access plate with welded studs or to a flange in order to isolate the
mounting holes from the pressurized environment.
Installation and Aiming
1. Install the Easy Aimer and transducer assembly by bolting the mounting block directly to the bin or via
a mounting plate.
2. Leaving the sighting block binding screws fastened, loosen the angle block binding screws. Rotate the
angle block until the transducer is pointing at the desired angle.
Re-fasten angle block binding screws.
3. Loosen the sighting block binding screws and rotate sighting block until the transducer is pointing in
the desired direction. Sighting reference graduations on the mounting block are 30° apart.
Re-fasten sighting block binding screws.
