The intelligent transmitter is made up of the sensor and the microprocessor (microcomputer). It makes full use of the computing and storage capacity of the microprocessor, the sensor data processing, including the measurement signal conditioning (such as filtering, amplification, a / D conversion), data display, automatic calibration and automatic compensation, the microprocessor is the core of intelligent transmitter. It can not only calculate, store and deal with the measured data, but also adjust the sensor through the feedback loop so that the collected data is the best. Because the microprocessor has all kinds of software and hardware function, it can accomplish the task that the traditional transmitter is difficult to complete. So the smart transmitter reduces the difficulty of manufacturing the sensor, and greatly improves the performance of the sensor.

characteristic

1, automatic compensation capability, the sensor can be nonlinear, temperature drift, time drift and other automatic compensation. Self diagnosis, after the power of the sensor can be self test, to check whether the normal part of the sensor, and make judgments. Data processing is convenient and accurate, can automatically process the data according to the internal procedures, such as the statistical processing, the removal of abnormal values, etc..

2, two-way communication function. The microprocessor not only can receive and process the sensor data, but also can feedback the information to the sensor, so as to adjust and control the measuring process. Can carry on information storage and memory, can store the characteristics of the sensor data, configuration information and compensation characteristics, etc..

3, digital interface output function, the output of the digital signal can be easily connected with the computer or the field bus.
