Microcomputer Control Electro-hydraulic Servo Universal Testing Machin

Description

1. This series machine adopt full digital broadband electro-hydraulic servo valve to drive precise hydraulic cylinder, to perform three closed-loop control to test force, displacement, deformation and thus finishes tests of tension, compression and bending tests. It accords with national standard GB/T*******2 Method for Tensile Test of Metallic Materials at Room Temperature and GB/T*********7 Electroydraulic Universal Testing Machine. Also complies with standard ISO, ASTM, JIS about materials requirements. It can automatically get upper yield force, lower yield force, non-proportional extension strength, total extension strength, tension strength, elasticity modulus, extension under maximum force and other mechanical performance index of various materials. 2.Utilizing upper hydraulic cylinder, with open jaw base, easy to install specimen and with good stability. ***** hydraulic servo loading system, adopting high precision broadbrand electrohydraulic servo valve to ensure system high precision, high efficiency, low noise, fast response. and its independent hydraulic clamping system makes specimen non-slipping during test. 4.Utilizing computer to perform test procedure control, data acquisition, processing, analysis(test data including: elasticity modulusE, tension strength Rm, Upper and lower yield points ReH, ReL etc.), test results accurate, reliable.
