Smart valve positioner, flameproof explosion-proof Exd, straight stroke, double acting, fail lock, stainless steel corrosion-resistant, split body anti-high temperature
External function: one of the seven major parts of the conventional mode of the hardware structure of the intelligent valve positioner. Through the data communication interface and field bus, the intelligent valve positioner can have two-way communication with handheld field communicators (such as 375, 475, SFC, etc.), PCs and process control systems, and these external devices also have part of the intelligent valve positioner Functions such as remote configuration, initialization, calibration; data storage (configuration files, trends, status); status monitoring and fault identification and alarming; predictive maintenance and asset management, etc., equipment integration and powerful system capabilities can boost intelligence Interoperability and high availability of valve positioners.
