Cylinder Profile Loading Apparatus (CEN / BS Standard)

- 12" Diameter ID X 30" test cylinder with removable base plate used to secure load
cells, lower load reaction plate, upper load applying plate. The cylinder is built in
three interlocking sections which facilitate the test profile assembly and disassembly,
as well as, enhancing the variability of the test profiles in the operators testing
program.
- (3) 10,000 pound load cells with summing box and indicating meter (better than 1%
accuracy of reading from 3,500 pounds of force to 30,000 pounds of force)
- Pneumatic constant loading system which can apply 500 to 20,000 (AR-S-AA-000)
or 30,000 (AR-S-AA-200) pounds of force throughout its 3" stroke with shop air of
less than 105 psi Force controlled via a precision "constant-bleed" regulator
- (2) Analog upper plate settlement indicator with 1" range and 0.001" (0.0254mm)
resolution with adjustable mounts which allow variable positions

Auxiliary Data Output

To have an analog output added to the digital readout of the load cell system a charge
is added.

Settlement Gauge
BT Technology Inc. offers (2) displacement indicators 1" X 0.001" res. with
the system.
You request an accuracy of 0.01mm (0.00039"). Most indicators with this
accuracy are usually fragile and have limited travel capabilities.
BT Technology Inc. offers in place of the analog indicators:

(A)
(1) Digital (metric / English selectable readout) upper plate settlement
indicator with 1" (25.4mm) range and 0.0005" (0.0127 mm) resolution with adjustable
mounts which allow variable positions

(B)
(1) Digital (metric / English selectable readout) upper plate settlement indicator with
over 5" (127 mm) range and 0.0005" (0.0127 mm) resolution with adjustable mounts
which allow variable positions

NOTE: The application of 20,000 pounds of force with the pneumatic loading
system refers to the force from the ram before any loss from friction of the aggregate
to the cylinder wall. The total 20,000 pounds may not be delivered to the lower plate
and the load cells.
The draft standard asks for loading from 200 to 1,500 kPa (3,000 to 25,000
pounds of force) over the 12" diameter lower plate. The 20,000-pound loading system
is limited to a 20,000 pound max before the loss due to aggregate/wall friction. It is
possible to develop friction losses over 25% of the applied load.
To more closely replicate the performance oriented properties which this test
attempts to measure, BT Technology Inc. chooses to utilize a constant loading
system to maintain a constant compressive load throughout the duration of the test.
This loading system is identical to the loading configuration which BT Technology Inc.
uses on several of our devices which require high compressive or tensile loads.
If you desire we could substitute a mechanical of hydraulic loading system
that would be less expensive, but would not maintain a constant compressive load as
the profile shifts and settles and would require a technician to make adjustments.

X-Z Axis Deformation Measurement Device

- Z-axis indicated via a digital indicator with 12mm travel by 0.001mm resolution
- X axis indicated via a digital indicator with 150mm travel by 0.01mm resolution
- X-axis travel uses rigid cast slide mechanism with a manual hand-wheel leadscrew
drive. X-axis digital indicator is securely fastened to this mechanism.
- An 12" X " 12 aluminum plate is mounted to the X Axis slide to facilitate the
positioning (or securing) of the test metal for measurement.
- The Z-axis digital indicator features a rigid but adjustable bridge mount over the
X-axis slide mechanism. This set up will allow the quick yet accurate positioning of
the indicator in the most appropriate X or Y-axis location relative to the test metal
deformation.
