Simpletech instruments manufactures numerically controlled automatic double screw spring testing machine / universal testing machine to cover up to 10,000 kg. The machines are rated with different resolution combinations for different load capacity such as 200, 1,000, 2,000, 5,000 and 10,000 kg. A single load cell measurement is determined into four ranges to attain very fine resolution compared to the capacity. Due to this multiple range feature, different capacity machines are not required. Smooth operation is ensured by the ball screw mechanism. The extra fine micro stepping drive used in the machine attains accurate positioning and loading control. These machines are electronically compensated for deflection errors and thus guarantee most accurate readings. Physical overload protection guarantees the safety of the load cell. The system is standalone [without computer] or through computer. The windows-based interface of the machine is easy to use having many features. Testing of spring is very simple and accurate due to the programmed test cycles with variable speed controls. The program entry feature of the software helps the user to make the own programs. It gives online display of the test results along with all readings, which ensures the visibility of the performance of the specimen being tested. The test results can be stored to use afterward and can be displayed and printed in tabular or graph forms. The machine can be modified for automatic testing of other products such as micro switches, solenoids, diaphragm springs, mechanisms, etc.
