Trends in IoT pressure transmitters

Time: 2018-10-18

In our view, the Internet of Things is divided into two parts: the civilian Internet of Things and the industrial Internet of Things. The civilian Internet of Things is the Internet of Things that everyone often talks about, including smart homes, smart objects, intelligent transportation, smart security, smart power, and smart medical care, etc. They are closely related to everyone's life, and naturally become the focus of everyone's attention. There is also the industrial Internet of Things that we talk about in these two years, with the intensive introduction of industrial operating systems (cloud-based open IoT operating system (PaaS)) of major brands at home and abroad, and the rapid development of the Internet of Things has enabled the previously unknown large-scale petrochemical plants to upgrade to the safe, environmentally friendly and energy-saving smart manufacturing industry.

With the implementation of the "IoT pressure transmitter specification" - GBT34073-2017 officially implemented on February 1, 2018, the Internet of Things pressure transmitter was born. IoT pressure transmitters have special IoT characteristics requirements: including identification requirements, pressure transmitters should have an identifiable identity; operability requirements, pressure transmitters should be operability; credibility requirements Pressure transmitter diagnostic mechanism, misoperation detection, alarm, etc. credible; network security, pressure transmitter should meet the security requirements of the Internet of Things, such as different levels of access rights; and data and Document structure. At present, the accuracy requirement of pressure transmitter for process industry users is 0.075%. The specification specifies 7 accuracy levels of 0.02%, 0.05%, 0.1%, 0.2%, 0.5%, 1% and 1.5%. From the 0.2% to 1.5%, the four lower accuracy levels are more used for the civil Internet of Things, while the 0.02%, 0.05%, and 0.1% accuracy levels can be used for the process industry IoT, while large-scale The industrial IoT application may be based on 0.02%, only the pressure transmitter reaches 0.02% accuracy level can truly realize the value of the process industry IoT pressure transmitter.

LEEG is a professional pressure transmitter manufacturer, focusing on the design and development of high-precision mono-silicon pressure transmitters, continuously improving the quality of pressure transmitters to serve users, and actively explore new pressure transmitters for intelligent manufacturing.
