In the general sense, the pressure transmitter is mainly composed of three parts: sensor sensor (also known as pressure sensor), measurement circuit and process connector. It can transform the physical pressure parameters that the pressure measurement component sensor feels into the physical pressure parameters of the gas, liquid and other physical pressure parameters into a standard electrical signal (such as 4 ~ 20madc, etc.) to provide the second instrument such as the alarm, the recorder, the regulator and other second instruments for measurement and instructions. Process adjustment

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.
