Principle and characteristics of intelligent pressure transmitter

Intelligent pressure transmitter is composed of sensor and microprocessor (microcomputer). It makes full use of the computing and storage capacity of the microprocessor, and can process the data of the sensor, including the conditioning of the measured signal (such as filtering, amplification, A/D conversion, etc.), data display, automatic correction and automatic compensation, etc.

Microprocessor is the core of intelligent transmitter. It can not only calculate, store and process the measured data, but also adjust the sensor through the feedback loop to optimize the collected data. Because the microprocessor has various software and hardware functions, it can accomplish tasks that are difficult for traditional transmitters. Therefore, the intelligent transmitter reduces the manufacturing difficulty of the sensor and improves the performance of the sensor in a large range.

Features:

1) Automatic compensation capability, which can automatically compensate the nonlinearity, temperature drift and time drift of the sensor through software. Self-diagnosis can be performed, and the sensor can be self-checked after power-on to check whether all parts of the sensor are normal and make a judgment. Data processing is convenient and accurate, and data can be automatically processed according to internal procedures, such as statistical processing and removing abnormal values.

2) Two-way communication function. The microprocessor can not only receive and process the sensor data, but also feed back the information to the sensor, thus adjusting and controlling the measurement process. Information can be stored and memorized, and the characteristic data, configuration information and compensation characteristics of the sensor can be stored.

3) Digital quantity interface output function, which can connect the output digital signal with computer or field bus conveniently.
