Abstract This paper describes the design of a sensor test system involved in the design of sensors including: temperature sensors, humidity sensors, pressure sensors, pressure sensors, flow sensors. Involved in the instrument hand operation, data logging devices, inverter, AI industrial smart regulator, the AIJ smart regulator and so on implementing agencies inverter and control valve. The design of the sensor test system is designed for electrical specialty (electrical engineering, automation, testing equipment and instruments, etc.) the design of the integrated test device. Complete a typical sensor (temperature, humidity, pressure, flow, level, electrical parameters) testing and validation, and implementation of the controlled object modeling, system design and system stability analysis, system parameter tuning, system performance Index test.training and research projects for future development in the automatic control system design, integration, installation, commissioning, operation, Maintenance, repair and so lay a foundation. Can also undergraduate, graduate, professional teachers and researchers engaged in the control experiment, training and scientific research provides an important platform.
