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-PT105Ⅱ series Smart Pressure Transmitter supports HART, FF, and PA protocol and can measure pressure, differential pressure, liquid level, flow, and other industrial parameters. It can be widely used in the petroleum, chemicals, electricity, and metallurgical industries, etc..

Precautions for installing pressure transmitter

How is the pressure transmitter connected to the measured medium?​​

An industrial gateway is a type of gateway specifically tuned and designed for industrial environments and Internet of Things (IoT) applications.

Temperature transmitter is a commonly used measuring instrument, using thermocouple and thermal resistance as temperature measuring elements.

Application of Differential Pressure Transmitter Basic situation The electrolytic repolarization cell is the first forced circulation ionic membrane electrolysis device put into operation in a factory, with a designed annual output of 2x10⁴t caustic soda. The main equipment is two MBC ion membrane electrolyzers, the working medium is: brine, magnetism, chlorine, hydrogen. The device was put into use in January 2008.

Measuring instruments in Bulk Cryogenic Tank Level Monitoring are used to measure the level of cryogenic liquified gases.Differential pressure is a simple and reliable way to monitor the liquid level in cryogenic gas tanks. These sensors work by measuring the pressure at both the top and bottom of the tank and calculating the pressure difference of the two ends.
