General description
General description
Introduction
The new Digimax Compact-Line compression testers are ideal for commercial laboratories and production control to test cubes, cylinders and blocks.  They can be fitted with accessories to perform other tests. See accessories.
The Digimax Compact-Line testers feature:
Frame
Four column high stiffness welded frame tested for stability to EN 12390-4.
Heavy duty spherical seat in lubricating oil bath, allowing initial free alignment at the initial contact with the specimen and automatic jamming up to the end of test.
Compression platens
Series 50-C46xxx and 50-C56xxx are fitted with 300 mm dia. platens which are suitable for testing cylinders up to dia. 160x320 mm and cubes up to 200 mm.
Surface hardness is 55 HRC, flatness tolerance 0.03 mm. Traceable certificate of surface hardness available on request. See Upgrading options.
Series 50-C47xxx and 50-C57xxx are fitted with rectangular platens 310x510 mm that are suitable for testing cylinders up to dia. 160x320 mm, cubes up to 200 mm and blocks.
Surface hardness 55.5 HRC (600 HV) , flatness tolerance 0.05 mm. Traceable certificate of surface hardness available on request. See Upgrading options.
Hydraulic power unit
Dual stage pump: low pressure/high delivery for fast piston approach and high pressure/low volume for loading. Fitted with special pressure-compensated proportional valvefor the manual preset of load rate requiring just occasional operator's intervention.
Digimax redout unit
Hardware
132,000 points effective resolution, three channels, touch screen graphic display 240x128 pixel, sampling rate 50/sec, large storing capacity on USB pen drive, test data downloadable to PC, Ethernet port, real time management software (optional, see accessories 82-SW/DM DATAMANAGER)
Firmware
Simultaneous display of load-specific load, actual load rate and load/time graph; LAN connection to PC; advanced memory management; multi coefficient calibration.
Recording facility of up to 10 test profiles for each channel including type of test (e.g. compression, flexural, indirect tensile), specimen size and shape, load rate, standard in use and other general informa­tion. Each one of the recorded test profile can be recalled automatically to save time
Safety features
Includes: Max. pressure valve to avoid machine overloading; piston travel limit switch; emergency stop button; front door and rear transparent fragment guard.
