Smart valve positioner, straight stroke, double acting, fail lock, stainless steel corrosion-resistant, split body anti-high temperature vibration
Data processing unit: one of the seven major parts of the conventional mode of the hardware structure of the intelligent valve positioner The data processing unit is characterized by an on-board microprocessor. The software and hardware can provide a variety of functions. The data processing unit of different products will be quite different. The functions that can be realized are: control operation function, configuration configuration, calibration, Tuning, condition monitoring and identification, external process control functions, self-diagnostics, trend logging and data storage, and some functions (eg configuration, trend logging) can be distributed to external devices that are temporarily or permanently connected to the data communication interface. Only a few intelligent valve positioners have the function of local online testing and fault diagnosis, and the diagnosis results are stored in the local machine, which realizes all data processing of predictive maintenance without relying on the upper computer.
