Test signal:
stress / Strain pressure pulsation flow / Velocity vibration temperature
Project characteristics:
➢ The signal type is complex, dynamic and static signals are collected at the same time, and the module is required to set the sampling frequency separately;
➢ The real-time remote transmission function of test data is required to realize data sharing while data acquisition, storage and analysis;
➢ It has the sensor calibration function to calibrate the primary coefficient and constant of the sensor;
➢ Each part can run independently, or network synchronization test can be conducted; Capacity improvement:
➢ dynamic / The static signal test system is integrated, and all signal time axes are synchronized;
➢ Networked synchronous acquisition and remote software control;
➢ The test data is transmitted to the remote computer (outside the system) in real time for special software calling for processing and analysis;
➢ Realization of large-scale comprehensive test capability
