| Abstract: | In order to remedy the defects like the unitary measurement range,unit,and output current,which are commonly seen in the current transmitters,a MCU-based intelligent differential pressure transmitter is introduced.This design adopts the 24PC series pressure sensor produced by Honeywell Corp.and 78F0513DA MCU produced by NEC Corp.in Japan as its core components.This intelligent differential pressure transmitter can promptly detect the air pressure or non-corrosive gas.The DIP button of the transmitter and the reset button make it possible to reset,select a new unit and conduct zero-point correction on the spot.The different current output ranges can be set according to the different requirements of customers,which boasts its reliable operation and high accuracy. |
