The stainless steel probe DCL 551 with RS485 in-terface uses the communication protocol Modbus RTU which has found the way in industrial communication as an open protocol. The Modbus protocol is based on a master slave architecture with which up to 247 slaves can be questioned by a master – the data are transferred in binary form. DCL 551 has been designed for hydrostatic level measurement in sewage as well as for viscous and pasty media. Basic element is a robust and high overpressure capable capacitive ceramic sensor. Nominal pressure: from 0 ... 40 cmH2O up to 0 ... 200 mH2O Output signal: RS485 with Modbus RTU protocol Special characteristics ► diameter 39.5 mm ► excellent long term stability ► especially for sewage, viscous and pasty media Preferred areas of use are: Sewage — waste water treatment — water recycling Fuel and oil — level monitoring in open tanks — with low filling heights — fuel storage — tank farms / biogas plants
