Automatic Ring And Ball Softening Point Apparatus

Automatic Ring and Ball Apparatus is used for determining softening point of bituminous materials by ring and ball method.

Operation / Working Principle

The device is Microprocessor controlled and has Colored, Large Touch screen display. Two bitumen samples casted in shoulder brass rings while being held in horizontal position, temperature is increased controlled according to the standards.
The softening point is the average of the temperature values read from the thermometer when each ball embedded in the disc shaped bitumen samples drops below 25.0 ° 0.4 mm. The softening point is detected by the photoelectric sensors and the temperature is measured with the PT100 sensor.

Test Range

Single test option is available as 30 C to 80 C for water.

Cooling System

The cooling system is integrated to the device. The cooling system ensures that the temperature of the test liquid is reduced rapidly and the stable temperature is reaches the temperature of the standard are achieved and reduces the time between two tests.

Components / Supply

Automatic Ring and Ball Apparatus consist of 2 steel balls, Frame (thermometer and ring holder, ball centering guide and bottom plate), 2 brass rings and 800 ml glass beaker.

Optional Accessories

Thermometer should be ordered separately

• With the help of a magnetic stirrer with an adjustable speed control system, a homogenous temperature distribution is achieved in the vessel and temperature control in accordance with the relevant standards during the experiment is provided by the 0-10 V, VDC Analog SSR.
• Due to its custom software; selection of test method and test parameters, automatic start of the test, data acquisition, data recording and printing and calibration of the device can be performed. The device can save a total of 9 tests. Thanks to the USB port available on the device, the data can be transfered to the computer and opened in excel.
