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.
