Porous Material Density Determinations
The density of a porous (oil impregnated part) can be made
with the balance. Weigh the part (dry) prior to oil impregnation
and
record its weight. You must also know the density value
of the oil to be used in immersing the part before starting. In
this procedure, you will follow the method for solid density
measurements using water.
When Porous Material is selected and the Enter button is
pressed, a second display POROUS MATERIAL SETUP is shown.
Enter the dry weight of the porous material and the density of
oil used to impregnate the part.
POROUS MATERIAL SETUP
Dry Weight : 0.000
Density Of Oil : 0.000
Exit
Exit the POROUS MATERIAL SETUP display. The DENSITY SETUP
screen re-appears.
To Determine Wet Density
Wet density of the sample can be calculated by following the
normal Solid Density procedure using the oil impregnated part.
When in DENSITY SETUP menu, turn off Porous Material, then
follow previous solid density measuring procedure.
ADJUSTMENTS
START/ACCEPT
When the START key is selected, pressing the Enter button will
start the Density application. The screen displays “Place Weight
In Air, Press Enter” message and the Density process has
started. At this point, the soft key has changed into an ACCEPT
key. When the ACCEPT key is selected, the weight value has
been accepted as valid data.
SETUP
When selected, the DENSITY SETUP screen will be displayed.
TEMP/AUX D/SINKER
Depending on the setting, this will allow manual editing to the
Temp field, the Aux. D field, or the Sinker field.
Library Name:
Allows storage and recovery of parameters and results. When
a library is recovered, the library name will replace the
application name in the application mode screen. The library
name has maximum of 8 characters.
Mode: Solid Density, Liquid Density (default is Solid Density)
Allows selection of mass for density calculations.
Auxiliary Liquid: H2O, Other (default is H2O)
Allows selection of type of liquid for density calculation. If water
is selected, the liquid density is fixed to 0.9971 g/cc and the
temperature of the water can be manually entered. If other is
selected, the density of the liquid can be manually entered.
Auxiliary Density: 00.000
When Auxiliary Liquid is set to water, Auxiliary Density is fixed
to 0.9971 g/cc. When Auxiliary Liquid is set to other, the density
of liquid can be manually entered.
Temperature: 00.00
When Auxiliary Liquid is set to water, the temperature of the
water can be manually entered.
