Smart valve positioner, intrinsically safe explosion-proof Exia, angular stroke, single acting, fail lock, stainless steel corrosion-resistant

Human-machine interface: one of the seven major parts of the conventional mode of the hardware structure of the intelligent valve positioner. Only when the data generated by the valve positioner can be interacted with externally, it can be classified as intelligent. The human-machine interface is an important tool for interaction and should be able to read data (local display), provide input configuration operations, and request access to data (local keystrokes). Early intelligent valve positioners did not have local display and local operation buttons, and provided access through data communication interfaces and external devices (hand-held field communicators or PCs). At present, most intelligent valve positioners have local display LCD and local operation buttons, the difference is only the specific form of LCD display and more or less buttons.
