The main purpose of a structure test is to obtain mechanical capability data of the tested specimen. The equipment doing data sampling is called Data Acquisition System.
Usually the data acquisition system is an independent system. It can work separately from the structure testing system just doing data acquisition. They only worked together when the operator wants to do data acquisition during the test.
Popwil can provide the structure testing system without data acquisition system if the customer already had one. Popwil controller can output the control parameter such as load and piston displacement of the actuator to the data acquisition system by means of analog signal.
Popwil can provide the structure testing system with data acquisition system with the communication function between them. This can save the input channel of the data acquisition system, reduce the quantity of the connecting line, and increase the reliability.
