Description

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. Features - Nominal pressure: from 0 ... 40 cmH2O up to 0 ... 200 mH2O - accuracy: 0.35 % (opt. 0.25 %) FSO - output signal: RS485 with Modbus RTU protocol - diameter 39.5 mm - excellent long term stability - especially for sewage, viscous and pasty media Optional features: - diaphragm ceramics Al2O3 99,9%
