ODR, series SRT-200B is used to evaluate and determine the rubber compound characteristics. For this purpose, a sample of vulcanizable rubber compound is place in the die cavities and a rotor is placed between two dies filled with rubber compound, but the temperature of dies should reach to a certain level previously. Test starts with just one click and the dies get closed, then the rubber compound surrounds the whole disc; disc starts swinging with a predetermined amplitude (1º, 2º, and 5º). This will create a sinusoidal variable strain in the test piece and applies a sinusoidal shear strain on it. Torque meter connected to rotor axis measures the applied torque, the value of which depends on the stiffness of the shear module for each rubber compound. Temperature controllers, with fast response, provide a constant temperature for testing as per standards. Torque-temperature curves are registered displayed constantly as a function of time. Rubber specimen stiffness increases as the vulcanization process keeps going. Test is over only when the test piece is cured, and the registered torque has reached to the balanced value or has been reversed. If the curing curve was ascending, then test is over upon reaching to a certain torque or a predetermined time; the complete results are displayed under the curve. Automated sample removal tool enables the operator to take out the cured specimen and clean the disc. SRT-200 software performs all test procedures automatically. Operator can use an ordinary PC when the machine is connected to serial port; no network interface card (NIC) is required. The machine dies are of modular design to reduce the time and cost. Dies consist of heater, sensors, insulating material, body, and standard chamber; each of these parts and components can be replaced or repaired as an individual part if needed. Change in swinging angle is applied mechanically and part replacement is not required; the operator should only set the crank manually. All electronic sections of SRT-200 are integrated in an internal board, connected to a PC via RS-232. Due to digital signal processing technology (DSP), the mentioned board is highly qualified that no setting is needed; its installation and replacement is easy so that a technician can replace it within a couple of minutes.
