The Orton
Model SP-1000 / SP-1100 has been designed to
automatically monitor the elongation of the sample fiber and calculate
the Littleton softening point according to the ASTM C-338 method.
Changes in the softening point temperature can be used as an indication
of changes in batch chemistry from raw material changes or batching
errors.
Automatic
Softening Point Determination
軟化點全自動測定, 測定時間只需5分鐘
It takes 5 minutes to measure the Littleton Softening Point of a
glass fiber. It's simple. After the test fiber is pulled to meet the
ASTM C-338 specified dimensions, the operator places the fiber into the
preheated furnace, aligns the fiber in the laser path, pushes the START
button, and walks away. The system does the rest. The operator is free
to perform other tasks. Five minutes later, the operator returns and
reads the Littleton Softening Point Temperature. It's that easy. The
SP-1000 automatically calculates the rate of elongation and displays
the softening point temperature which eliminates operator differences, judgements, and errors. The Model SP-1000 is a FAST, EASY, ACCURATE,
RELIABLE, and REPRODUCIBLE method for QC checks on batch chemistry
changes.
Description
This
system is comprised of the ASTM specified furnace to heat the fiber; the
Orton PID controller to operate the furnace according to the ASTM C338
thermal cycle, laser system to monitor the elongation of the test fiber,
the Orton on board computer with internal logic to determine the
softening point, digital display panel for displaying the softening
point temperature, and software for an independent computer (provided by
the purchaser).
Operation
The system is initially heated to an
equilibrium soak temperature, and waits for the next test. After the
fiber is inserted and aligned, and the START button pushed, the Orton
controller heats the furnace at 5ºC per minute and captures the
temperature and laser signals. As the temperature increases and the
fiber elongates, the laser system follows the tip of the elongating
fiber and continuously sends its signal to the on board computer. The on
board computer calculates the elongation rate as a function of time, and
concludes the test once the elongation rate exceeds 1.05 millimeters per
minute. The on board computer selects the temperature at which the
elongation rate is 1.00 millimeters per minute and displays that
softening point temperature until the system is reset. The furnace
automatically cools to the soak temperature in about 15 minutes, and is
ready for the next test. The on board computer can store data for up to
10 tests.

If desired, a separate, independent computer system (not included) can
be connected to the Orton controller console via a RS232 port. The
independent computer, using Orton supplied software, can display and
store the fiber elongation rate, time, and temperature. The data is
stored in a text file on the hard drive for later independent review,
analysis, or permanent storage.
