ABOUT THIS MANUAL
This instruction manual, PL-327, covers the installation, operation and maintenance of the MMI-2 belt scale.
It is imperative that this manual be read and understood before installation and start up of any component of
the weighing system to which the MMI-2 is being applied. Adhering to the installation and operating
procedures will insure a quick, trouble free installation and allow for the maximum accuracy and reliability of
your weighing system to be achieved.
As the MMI-2 belt scale is used in conjunction with an integrator and optional speed sensor, the instruction
manuals covering these components must be read as well.
ABOUT THE MMI-2
The Milltronics Multiple Idler (MMI-2) is a belt scale application using two Milltronics Single Idler (MSI) belt
scales in succession. The scales are designed to be inserted into belt conveyors for continuous weighing of
dry bulk solids.
Each MSI is comprised of the following:
- one weighbridge c/w two load cells with cables run in a
common flexible conduit
- test weight(s)
The addition of an idler (supplied and installed by customer) to each weighbridge completes the weighing
assembly. The MMI load cells provide an electronic signal, proportional to load, which is fed to the Milltronics
CompuScale series integrator. Thus, weighing is accomplished without disturbing the process and without
affecting the process material.
The MMI-2 is used where conveyor belt speeds or belt loading charactistics result in conditions that
necessitate extending the weighing time beyond the capibilities of a single idler scale. It is also well suited for
applications that require higher sustained accuracies, such as production control inventory accountability or
where certification for trade purposes is required.
It is important to understand that the MMI-2 is an accurate and repeatable force sensor. Its performance is
ultimately dependent upon the conveyor system and the quality of the installation and alignment.
