Semi-Automatic Compression Test Machines
Semi-Automatic Compression Machines are used to determine compression, split and flexural strengths, usually applied to materials of high compression but low tensile strength in which the specimen is subjected to increasing compressive forces until failure occurs.
Reliable and consistent testing on a wide range of specimens is achievable when using the UTEST Semi-Automatic compression testing machines.
These compression testers are produced as a result of endless research studies to enhance the machines with the latest technologies to conform with the latest standards.
These machines also meet the requirements of CE norms with respect to the health and safety of the operator and their user-friendly design enables an inexperienced operator to complete the tests.
Applications
-
Early age unconfined compression strength test
-
Unconfined flexural and splitting tests by using proper accessories
-
Mortar (Cement) compression tests by using proper accessories
-
Unconfined core testing
Components
A complete compression test machine comprises the following components:
Compression Frame - These are heavy-duty welded frames. The frames also include the platens as well as distance pieces to adjust the system for different sample sizes.
Semi-Automatic Power Pack - The motorised power pack is controlled by a pressure rate control valve to supply oil to the compression load frame. The operator can then vary the pace rate to suit the testing standard in use.
Digital Readout - the readout is designed for use with the load frames pressure transducer, it offers a real-time view of load and load pressure with peak hold capability and multi-point calibration.
Safety Features
- Maximum pressure valves to avoid machine overloading
- Piston travel limit switch
- Frontal and rear transparent durable Plexiglas guards
