AVP3000 Alphaplus electric / pneumatic smart valve positioner AVP3000 Alphaplus is microprocessor-based intelligent electric / pneumatic positioner. AVP3000Alphaplus accept the opening of the controller transmitted DC signal control valve. In addition, AVP3000Alphaplus with on-site communications, automatic configuration, self-diagnostic function, which greatly improve the production efficiency of the plant. This is a use than conventional electric / pneumatic positioner is more, 100, when a specification can be used for various types of valve intelligent electric / pneumatic positioner. In addition, to improve the regulation and control performance of the valve and control valve for monitoring the operation (when the band opening signal transmission function), etc., can maximize the effect.
