Introduction The new MULTISPEED tester is the ideal solution for Road testing laboratory. The 50 kN capacity and the fully variable test speed of 0.2 to 51 mm/min make it possible to perform not only the CBR and Marshall tests, but many other applications as for instance Indirect Tensile test, Quick Triaxial tests, Unconfined and Uniaxial soil testing and, in general, all test to be performed under displacement control. The machine can be equipped with analogical or digital load/displacement measurement systems as well as with the specific accessories, to suit either the field or central laboratory requirement. Description The MULTISPEED tester feature a rigid two column structure with upper cross beam which can be set at various height. The load jack, DC motor and controls are housed in a specially designed base cabinet. When fit in the digital mode, test data are acquired and processed by the Digimax or by other similar instruments. One of the main features of the new MULTISPEED is the control of test speed which is first easily set and then shown on the display.
Furthermore, the test stroke can be set at the beginning of the test with automatic stop, avoiding to overload the machine and the specimen, thus assuring the operator safety. This important feature also permit to perform the speed calibration of the machine by micrometric manual adjustment by the operator. The display also show the travel direction of lower platen.

8 Bit Pcm Mono Wav File. The front panel is also fitted with an emergency button and two operating led: machine switched on and travel direction. Introduction: The new automatic MULTISPEED 34-V1172 is a versatile stand-alone machine; an ideal solution for road testing laboratories and generally for any test that requires displacement/speed control. The 50kN capacity and fully variable speed of 0.05 to 51 mm/min make it possible to perform not only CBR and Marshall tests, but also many other applications such as indirect tensile, quick undrained triaxial and unconfined/uniaxial soil tests. Description: The MULTISPEED tester features a rigid two-column structure with an upper crossbeam which can be set at various heights. The load jack, DC motor and controls are housed in an ergonomic cabinet.
Automatic control of the test speed/travel is ensured by the microprocessor. Prior to the test, the operator can impose travel limits for automatically ending the test. No external transducer is required for displacement measurement. Minecraft Texture Pack Maker Free. The firmware allows performance of transducer calibrations and setting of up to 10 test profiles, saving data onboard.
A real-time test graph and transducer data are displayed on the touchscreen. The machine has built-in data acquisition with four channels dedicated to two strain gauge load cells and two potentiometric linear transducers; one of each can be used during the test. An important feature is provided by the processing unit that controls the speed in a closed-loop mode, avoiding speed calibrations and tension fluctuation effects. The user-interface is a large touchscreen graphic display supplied with a stylus pen. The front panel is fitted with an emergency button for prompt stopping of the machine.
