Device functions:

1. YAW series micro-computer-controlled electro-hydraulic servo pressure testing machine is a new generation of hydraulic products of our company. It has force closed-loop servo control function and can realize equal load loading。

2, the test force is not divided throughout, the whole process of a resolution。The resolution of the test force is better than 10N, the relative error of the test force indication value is less than ±1%, and the test range is 2%-100% FS。

3, electrical control, software operation to meet GB/T 50081-2002 ordinary concrete compressive strength test method, especially suitable for a long time continuous work test site。

4, can achieve a long time to maintain the load, high load retention accuracy, can set complex compression test procedures。

5, the configuration of the corresponding fixture can meet the requirements of other standards of compressive test。

6, the test software built-in test standard network interface, test data can be transmitted to the network through this standard interface, the software manual and help document has a detailed description of this interface and the use of configuration methods, network software through this interface can be tested with the software for data exchange and transmission。We assist users in networking, but do not customize the network interface for users alone, nor do we assume the responsibility for consultation and coordination with the relevant network companies。If it involves sending software personnel to the user site service, corresponding fees will be charged。
