Product patent of invention
March 22th, 2016 , WNK IEC61158-2 transmission technology based intelligent fieldbus distributor is successfully awarded patent of invention.
WNK intelligent self- diagnostic fieldbus distributor (WAFD) is able to connect PROFIBUS PA onsite equipments (such as pressure transmitter, differential pressure transmitter, temperature transmitter and communicator) with WAFD. The WAFD can self-detect connection, open and short circuits conditions of PA main line, PA branches and PA equipment, and automaticly insulate breakdown PA parts, thus to solve connection breaking off caused by PA section fault and ensured safety working of of systems.
WAFD intelligent self- diagnostic fieldbus distributor has been widely applied in cement clinkers production line, and has been very popular in the field. With the development of industrial automatic technology, WAFD finds its big market in industries of power, chemical, metallurgy etc.
