Abstract

The invention provides a weighing sensor testing device and a weighing sensor testing system. The weighing sensor test device comprises a test bench; the pressure gauge is arranged on the test bench and is used for applying pressure to the weighing sensor to be tested and recording the actual value of the applied pressure; the data transmitter is connected with the weighing sensor to be tested and is used for transmitting a test pressure value detected by the weighing sensor to be tested; and the test end is connected with the pressure gauge and the data transmitter and is used for comparing the test pressure value with the real pressure value so as to obtain the precision of the weighing sensor to be tested. According to the invention, the test terminal is arranged, the test terminal is started after the weighing sensor to be tested is installed, full-automatic test can be realized, the whole test process is automatically operated, manual intervention is not needed, any parameter setting and other operations are not needed, the operation flow is simple, the difficulty is low, and the test efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of load cells, in particular to a load cell test device and a test system. Background technique [0002] In the production process of load cells, due to the problems of metal strain gauges and production and processing technology, the performance consistency of different load cells will be different. Therefore, it is usually necessary to test the accuracy of the sensor during use. After the test, record the accuracy of different load cells before use, so as to reduce the measurement error in the subsequent measurement. [0003] However, the existing test solutions need to manually set a variety of parameters during testing, the operation process is complex and difficult, many equipment are required, the equipment is bulky, and the test efficiency is low. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to provide a load cell test equipment and a test system, so as to solve t...
