Computerized Compression Testing Machine

PROPERTIES:-
Applications :

• High performances, high resolution test for routine and complex tests and calculation with measurement of sample strain.

Main features:

• High precision and resolution
• Control system by PC and keyboard
• User friendly software for management of the console also for non-expert users
• Performance of many types of tests
• Software calibration
• Real time monitoring of test data (load, stress, strain, time) either in graphic format or as data
• Real time processing of test data (e.g. determination of E-modulus) either in graphic format or as data
• Load- hold function (Optional)
• Input of dimensions and descriptions of the sample: age, preparation, etc.
• Input of descriptive and administrative test data: client, test centre, place of test, etc.
• Input of test parameters and settings: load rate, peak, sensitivity, etc.
• Input of data after test completion: type of failure, etc.
• Single and/or batch storage of test data in ASCII and/or other defined formats
• Printout of customisable certificates

General description:
The main feature of this Computerised Control System and Hydraulic Unit is the maximum flexibility of the PC used as a friendly interface in terms of customisation of tests, processing of input and output data, connection to the existing laboratory network, etc.

The Computerised Control System enables the automatic performance of a number of functions, for example:

Rapid piston approach Zeroing User defined load rate Failure detection Unloading, etc.

Technical specifications:

The standard version can control upto two load/hydraulic frames (Special optional feature) The system is supplied complete with PC and printer.

Hydraulic system:

Max. working pressure: upto 600 bar Double stage pumping system High delivery - low pressure for fast approach of the piston Low delivery - high pressure for test execution Maximum pump capacity: 3 lpm at low pressure ; 1 lpm at high pressure (approx) Resolution: 2000 divisions or better Date and time function (approx)

User interface:
The system is entirely controlled from the PC. Display and keyboard are available for basic factory settings and eventual local purposes.

Large display Alphanumeric keyboard Graphic interface by icons. PC and software PC and printer selected among latest models The PC allows remote control of the whole system including the automatic test execution: rapid piston approach, zeroing, performing of user defined load/stress rate, failure detection, unloading, graphic and numeric management of test data and results Manual control of the system available for easy calibration check

Main test data:

Sample dimensions and features (type, exact size, ID, weight, age, density etc.) Descriptive and administrative data (client, test site, operator name, dates etc.) Test settings (reference standard, load rate, peak sensitivity etc. Units selection (metric and SI).

Physical specifications

Power rating: 750W+ depending upon machine capacity Voltage: 230 V, 50 Hz, 1 ph. or 440 V, 50 Hz, 3 ph.
