ARRANGEMENT FOR SELF-MONITORING OF FLOAT-CONTROLLED LEVEL STANDS WITH MAGNETIC SWITCHING DEVICES

摘要

Arrangement for self-monitoring of float-controlled level sensors with magnetic switching devices. The invention relates to the field of metrology and its application is in facilities for measuring the Fluessigkeitsstandes, especially in high-pressure steam boiler systems, possible. Essential features of the invention are the arrangement of safety logic units (SLE) for processing the signals of magnetic switching devices (MSE) of two level sensors (FSG), a signal tableau unit (STE), a controllable Verzegegergliedgliedes (SVG), a control unit (RE) and a safety intervention unit (SEE ) for signaling and controlling the filling levels (Niedringst & NW !, instantaneous & MW !, maximum water level & HW!) of high-pressure boiler systems.
