EHC-2300 System for Flexural and Compressive Strength Testing Machine

EHC-2300 bending compression testing machine system
 
The system is composed of our independently developed EHC-2300 electro-hydraulic servo measure and control box, GS-82A digital servo valve group and SuperTest V7.2 testing and control software.

It is suitable for working together with the the electro-hydraulic flexural and compressive strength two work position testing machines from testing machine manufacturers, to compose the electro-hydraulic servo flexural and compressive strength testing machine.
 
  • Our EHC-2300 system is able to implement constant speed loading, load maintenance, constant speed unloading control for the bending work position and compressive work position through shifting the electromagnetic reversing valve. It has the features of high control precision, strong adaptability, long-term stability and so on.
  • The system can implement the whole control process from data acquisition, PID computing and Ethernet communication operation to the output control in a short period of time, thus achieve the accurate closed-loop control for the testing machine.
  • It has up to 15 linear compensation and correction function and greatly improve measurement range and measurement accuracy of the sensor.
  • The measurement unit adopts high precision 30MPa pressure sensor and 10kN load sensor.
  • The controller uses Cotex_M3 32-bit high-speed ARM chip as the master chip, has high computing speed and data processing capabilities.
  • Has one input channel for pressure sensor or load sensor: the channel adopts the separate 24-bit A/D converter for high-precision data sampling. The effective internal code is up to ± 200000.
  • One digital servo valve interface: to connect GS-82 digital servo valve.
  • One electromagnetic reversing valve interface: to connect DC24V rapid return oil electromagnetic valve.
  • One overload protection interface (normally closed contact): connect to the oil pump control circuit. Automatically stop oil pump when testing machine is overloaded.
  • The system uses the PID control strategy to achieve the compressive load or bending closed loop control, as well as achieving the functions of constant speed loading, load retention and constant speed offloading. Loading speed can be configured freely.
  • One 100MHz Ethernet communication interface, achieve high-speed data communication with PC. Has the function of real-time data acquisition upload and real-time delivery of control instructions, so as to achieve the purpose of controlling the testing machine by PC in real-time.
  • One RS232 microcomputer communication interface, can be connected with our EPC series touch-screen tablet computer, to achieve the purpose of controlling pressure testing machine through touch-type tablet computer.
