DCL 571 Stainless Steel Probe with RS485 Modbus RTU Ceramic Sensor accuracy according to IEC 60770: standard: 0.35 % FSO option 0.25 % FSO Nominal pressure from 0 ... 1 mH2O up to 0 ... 100 mH2O Output signal RS485 with Modbus RTU protocol Special characteristics ► good long term stability especially for waste water The probe was developed for level measurement in waste water, sludge or water courses. The mechanical robustness of the flush ceramic diaphragm facilitates an easy disassembly and cleaning of the probe in case of service. reset function Compared to the level probe DCL 551 the outside-diameter is only 22 mm, which allows an easy installation and back fitting in 1″ tubes or in cramped fitting conditions. different designs drinking water certificate according to DVGW and KTW The stainless steel probe DCL 571 with RS485 interface 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 will transfer in binary form. different kinds of cables and elastomers Preferred areas of use Water groundwater and level monitoring Sewage waste water treatment, water recycling Fuel and oil tank battery, biogas plants BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
