(1) Signal processing function. It can not only amplify signals, but also quantify them; it can linearize nonlinear signals; and it has low noise.
(2) Automatic diagnostic function. It can perform self-test, realize automatic zeroing, automatic balancing, automatic compensation, and automatic range selection of the sensor; check whether each part of the sensor is normal, detect faults in time and provide operation prompts.
(3) Software configuration function. The combination state of the hardware and software modules of the smart sensor can be changed through instructions issued by the microprocessor, thereby enhancing the sensor's performance and reliability. For example, detection, amplification, and communication interfaces are composed of hardware, while control and processing are completed by software, utilizing the strengths of both hardware and software.
(4) Interface Functions. Standardized interfaces are used, facilitating communication via RS232, RS485, and other interfaces. This enables remote control from the central computer, remote control of the measurement system, and transmission of measurement data to remote users.
(5) Human-computer interaction function. The computer, intelligent sensors and detection instruments are combined together and equipped with various display devices and input keyboards to enable the system to have human-computer interaction function.
(6) Information storage function. The intelligent sensor has an information storage function, which can store the measurement parameters and status parameters through EEPROM.
(7) Data processing function. It can not only measure the measurand, but also calculate unknown parameters based on the known measurand. It can preprocess the data and has the functions of judgment, decision-making and processing.
