Pressure transmitter (pressure transmitter) refers to the output as a standard signal pressure sensor, is a kind of acceptance of the pressure variable proportionally converted to a standard output signal instrumentation. It can feel the pressure measuring element sensor gas, liquid and other physical pressure parameters into a standard electrical signal (such as 4 ~ 20mADC, etc.), to supply the indication , recorder, regulator and other secondary instruments for measurement, indication and process regulation.
Intelligent instrumentation is developed with the maturity of microcontroller technology in the early 80s, and now the world instrumentation market is basically monopolized by intelligent instrumentation. The reason for this is the need for enterprise informatization, enterprises in the instrumentation selection, one of the necessary conditions is to have a network communication interface. Initially the data analog signal output
Simple process quantities, and then the instrument interface is
RS232 interface, this interface can realize the
point-to-point communication, but this way can not realize the networking function. Subsequently
The RS485 solved this problem.
RS485/MODBUS is now a popular networking method.
RS485/MODBUS is now a popular way of networking, which is characterized by simple and convenient implementation, and now supports RS485 instrumentation and a lot.
485 instrumentation and more, especially in the oil industry.
Especially in the oil industry, RS485/MODBUS is practically
The whole world, now the instrumentation business have also turned to support RS485/MODBUS, the reason is very simple, the original HART instrumentation want to buy a conversion port is very difficult and expensive, RS485 conversion interface is much cheaper and a wide range of interfaces. At least in the low-end market RS485/MODBUS will be the most important way of networking, the last two or three years will not change.
