BD Sensors DCL 571 Stainless Steel Probe with RS485 Modbus RTU with Ceramic Sensor, from 0 … 1 mH2O up to 0 … 100 mH2O, 22 mm Diameter

SKU: DCL 571 Category:

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 are transferred in binary form. 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. 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.
