Industrial instrumentation presents new highlights

The status of industrial instrumentation in industrial development is self-evident. In recent years, with the development of electronic technology and computer technology, industrial instrumentation has become more functional, and its reliability and life expectancy have also been improved. Today, its development shows new highlights.

First, the integration of system functions: With computer, power electronics and strong electrical control more closely combined, continuous control and intermittent control and use.

Second, the emergence of a new fieldbus architecture: expansion of the instrument's self-diagnosis function, and easy maintenance, the system connection is more reliable, easier, so the installation costs are greatly reduced, and the control scale is variable.

Third, the addition of new smart modules: new types of sensors such as fiber optic sensors, polymer sensors and biosensors will continue to emerge and will achieve rapid development.

Among them, the transmitter uses high-performance microprocessors and communications technology to achieve digital, communications, intelligent, improve the accuracy and range ratio, with temperature and pressure compensation, to achieve self-diagnosis, remote configuration, remote control adjustment zero , measurement range and PID control set point, and the use of dot matrix light column display technology, display measured variables and set values.

The detection instrument will continue to adopt new sensing technology and microelectronics technology, and it will be digitalized, intelligent, highly accurate, resistant to special media, special environments, capable of measuring limit parameters, non-contact measurement, and long-life direction. With the development of intermittent process control, on-line testing of various new types of instrumentation such as mechanical quantities, state quantities, and chemical composition will have new developments.
