Automatic Ring and Ball Apparatus
Product Code : EL-BTLE-10440
Quick Answer: The Automatic Ring and Ball Apparatus is a microprocessor-controlled tester that determines the softening point of bituminous materials per EN 1427; ASTM D36; AASHTO T53, using water or glycerol as the heating fluid. A sample disk held in a horizontal ring is forced downward 25.4 mm under a steel ball’s weight as it is heated at a prescribed rate, with the softening point taken by two light barriers and the temperature measured by a PT100 sensor, and the whole process run and logged automatically via the built-in software and graphic touch screen. It weighs approximately 16 kg, measures 530x300x280 mm, and runs on a 750 W power supply.
The Automatic Ring and Ball Apparatus is an innovative microprocessor controlled automatic tester which is used to determine the softening point of bituminous materials using water or glycerol as the heating fluid. In the test, a disk of the sample held within a horizontal ring is forced downward a distance of 25.4 mm under the mass of a steel ball as the sample is heated at a prescribed rate in a water or glycerine bath, and the softening point is taken by two suitably positioned light barriers with the temperature measured by a PT100 sensor.
The apparatus consists of a heater, cooling system, electric lifting system, and magnetic stirrer with speed control, temperature probe, glass beaker, ring and ball support, brass ring with steel ball and ball centering guides (2 pcs. each), light barrier system, microprocessor system and large graphic display with touch screen, RS 232 C port for PC or printer. A uniform temperature distribution in the vessel is maintained by a magnetic stirrer, equipped with an adjustable speed control system and the temperature gradient is strictly maintained during the test by the electronic system conforming to the relevant standards.
A software permits to select the test method and the test parameters, run the test automatically, store, retrieve and print data, diagnose and calibrate the instrument. Additional cooling system, permits to quickly cool down the sample allowing to handle the glassware and to perform number of tests during a day by reducing the dead times between consequent analysis.
