Application
The HM-2850 Multi-speed Load Frame is designed for those who
want a high-quality, but simple, multi-purpose load frame without
built-in data acquisition capabilities. The HM-2850 is ideal for
applications where the operator is either not concerned with data
acquisition; or, already has or is planning to construct their own
data acquisition system. With its large 7" color, touchscreen, the
HM-2850 provides the operator with the ability to precisely select
any speed with four decimal accuracy within the machine’s speed
range.
The HM-2850 features a quiet, direct drive stepper motor that
provides a range of loading speeds from 0.00001 to 2.00000 in/
min (0.00001 to 50.80000mm/min.). This speed range is more than
adequate for the majority of standard soil tests.
The HM-2850 also incorporates a separate, dedicated control to
accommodate 2.00000 in/min (50.80000mm). for use in Marshall
and TSR Testing, as
well as a rapid travel speed of 2.25 in/min for moving the platen
into position quickly. Speeds are controlled through the use of edit
keys and the digital display.
