The smart pressure transmitter offers a 4–20 mA output and HART communication, ensuring accurate, stable, and reliable pressure measurement for various industrial processes.
These explosion-proof pressure transmitters are microprocessor-based, high-performance sensors with accurate pressure measurement capabilities, a high-precision, high-stability intelligent pressure measurement device, and come standard with the HART protocol.
Principle
When pressure directly acts on the surface of the measuring diaphragm, causing a slight deformation of the diaphragm, the high-precision circuit on the measuring diaphragm converts this slight deformation into a highly linear voltage signal that is proportional to the pressure and proportional to the excitation voltage., then the chip is used to convert this voltage signal into an industry standard 4-20mA current signal or a 1-5V voltage signal.
