Abstract The role of the use of spring tension device volumes made in our lives, the more common, such as a dog lead rope, cleaners, etc. device volumes. Spring tension related to the products performance and quality, the need for testing. Paper discussed the principle of detecting spring, spring tension is designed to test the hardware system. Designed based on the Panasonic (FpΣ-c32) PLC, Proface touch screen (GP37W2), force sensors FAB-80, amplifiers, AD converters, consisting of stepper motor test system spring tension. Operation through the touch-screen parameters can be set up to achieve the control of various functions, but also through the touch screen display the test results and the status of currently running on the system for real-time monitoring.
Key words: spring tension, PLC, touch screen, step motor
