People who work with thermocouples a lot may also not know exactly how the cold junction of thermocouple (reference) works. To be able to discuss the cold junction, we first need a brief understanding of thermocouple theory and how thermocouples work.

Microcyber presented fieldbus and industrial wireless products at the exhibition.

HART and FOUNDATION Fieldbus demonstrably provide tremendous operational efficiency improvements for process facilities when deployed with continuous digital data transmission among instruments, asset management systems, and industrial internet of things (IIoT) platforms.

The product realizes the converter function from Modbus RTU to PROFIBUS PA, and it shall multiple devices with Modbus RTU protocol to PROFIBUS PA network.

intelligent temperature transmitter adopts field bus technology, is a new generation of intelligent temperature transmitter, is an indispensable field device in process control. The device integrates a wealth of functional modules, which can achieve both general detection functions and complex control strategies.

According to the recent reader survey of Control Engineering Chinese Edition and CONTROL ENGINEERING in the United States, the application and development of industrial Ethernet technology show the following seven trends

By analyzing the needs of users, we can roughly divide the technical requirements and expectations of users on the fieldbus into the following three levels:

APC3 is a fieldbus dedicated chip for the development of PROFIBUS DP intelligent slaves, supporting the complete DPV0 protocol. APC3 is fully compatible with SPC3LV and VPC3 working in DPV0/3.3V/1.5K dual-port RAM mode.

NCS-TT105 supports HART, FF, and PA protocols. It can be widely used in the petroleum, chemicals, electricity, and metallurgical industries, etc.

HART temperature board MS0210, using the fieldbus technology, is a new generation of smart temperature module and it is an indispensable field device for process control. It can be widely used in the petroleum, chemicals, electricity, and metallurgical industries, etc.
