Universal spring-what are the characteristics?

Universal spring machine plays an important role in the testing of mechanical equipment. It of features and advantage: pump noise low, performance stable, using life long; work cylinder plug used clearance sealed, friction small; independent of hydraulic clip pomade source, added holding force can regulation; proportion servo valve, action response fast, oil requirements low; sensor performance stable, precision high; independent of control device, big screen LCD displayed, keyboard operation; also can and computer online, all operation into computer control; tell force high, full range within not changes, and both inside and outside not points document; has automatically clear 0, and automatically calibration, and Features such as automatic diagnosis, automatic storage; the constant test load, constant deformation, constant displacement and stress rate and constant strain rate control, and no impact in a test switch has over current, over speed, Super test, travel and so on protection functions.
