General description
General description
Introduction
The Digimax control system for connection to compression and flexural testing frames, including the hydraulic power unit, the flow control valve and the digital measuring system, has been designed to fit all our models of compression and flexural frames ranging from 100 to 5000 kN and integrated obtaining a performance very closed to that of the Automatic testing systems.

Very often may be convenient to update an old compression tester, replacing for example the old pressure gauge and pump, with a modern and much more accurate control console as our Digimax Smart-Line. This application requires a suitable pressure transducer and connecting cable. See Pressure transducers

Description
The Digimax System is usually proposed as part of the compression machines (DIGIMAX, Semi-Automatic EN testers for cubes, cylinders and blocks, DIGIMAX, Semi-Automatic ASTM testers for cylinders, DIGIMAX, Semi-Automatic testers for cylinders, cubes and blocks), but it is available also as stand-alone control console. The two solutions are technically identical and can be selected conforming to customer requirement: the first solution is more economic and compact, the second is more ergonomic and flexible being possible to move it easily to fit another frame in the laboratory and it is also useful to update an old compression tester with a modern and much more accurate control console.
The Digimax System can be factory upgraded with a distributor block for connection and not simultaneous control of a compatible second frame. Furthermore, the front panel of the display unit is designed to incorporate a serial printer, programmed to print all test results and plot the Load/Time graph. See upgrading options.
The Digimax System can be completed, as option, with the Data Manager PC software (new release compatible only with SMART LINE units) for real time acquisition and management of test data. See accessories.
As specified, the compression and flexural testing frames have to be selected conforming to the standard in use and to the specimen shape and dimensions.
