The Orton Model ANS-800 / ANS-1000 has been designed to automatically monitor the elongation of a loaded sample fiber and calculate the annealing and strain points according to the ASTM C-336 (Method A). Changes in the annealing and strain point temperatures can be used as an indication of changes in batch chemistry from raw material changes or batching errors.

Automatic Annealing & Strain Point Determination 測定時間只需25分鐘

It takes 25 minutes to measure the Annealing and Strain Points of a glass fiber. It's simple. After the test fiber is pulled to meet the ASTM specified dimensions, the operator simply places the fiber into the preheated furnace, applies the weight, pushes the START button, and walks away. The system does the rest. The operator is free to perform other tasks. Twenty minutes later, the operator returns and reads the annealing point temperature on the display panel. It's that easy. The ANS series automatically calculates the rate of elongation and displays the annealing point temperature which eliminates operator differences, judgement, and errors. If an independent computer system is connected to the ANS-800, both the annealing and strain point temperatures are calculated and displyed on the computer's monitor. The system automatically measures and records the rate of elongation and applies non-arbitrary mathematical algorithms to extrapolate the strain point temperature so operator differences, interpretations, judgments, and errors are eliminated. The Model ANS-800 is a FAST, EASY, ACCURATE, RELIABLE, and REPRODUCIBLE method for QC checks on batch chemistry changes.

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 C336 thermal cycle, sample support system with sample load rod and weight, an LVDT system to continuously monitor the fiber elongation, the Orton on board computer with internal logic to determine the annealing point, digital display panel for displaying the annealing point temperature, and software for an independent computer (provided by the purchaser).

The system is initially heated to an equilibrium soak temperature 25°C below the expected annealing point, and waits for the next test. After the fiber is inserted and the weight applied, the START button is pushed and the Orton controller heats the furnace at 5ºC per minute. The temperature and LVDT signals of the elongating fiber are captured by the controller's on board computer, where the elongation rate is calculated and monitored. Once the elongation rate exceeds 0.60 millimeters per minute, the Orton controller cools the furnace at 4°C per minute. While the furnace is cooling, the temperature and LVDT signals are captured by the controller's on board computer for storage. Once the elongation rate falls below 0.10 millimeters per minute, the test is concluded and the annealing point temperature (elongation rate of 0.14 millimeters / minute) is displayed on the console display 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 for real time monitoring and analysis. During the test the fiber elongation rate, time, and temperature are displayed on the monitor and stored on the hard drive in a text file. At the conclusion of the test, the software automatically and immediately calculates the annealing point temperature (elongation rate of 0.14 millimeters / minute) and the extrapolated strain point temperature (elongation rate 0.0316 times the annealing point rate, or 0.004424 millimeters / minute) according to the ASTM C336 algorithms.

Or, if preferred, a separate, independent computer system (not included) can be connected to the Orton controller console via a RS232 port after the test is concluded. The data stored by the Orton on board computer is transferred to the independent computer's hard drive in text file format for later independent review, analysis, or permanent storage.
