hydrostatic level probe DCL 571

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%

The stainless steel probe DCL 531 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. Basic element is a high quality stainless steel sensor with high requirements for exact measurement with excellent long term stability. Features — nominal pressure: 0 ... 1 mH2O up to 0 ... 250 mH2O — accuracy: 0.25 % FSO — output signal: RS485 with Modbus RTU protocol — diameter diameter 26.5 mm — small thermal effect small thermal effect — high accuracy excellent accuracy — reset function Optional Features — drinking water certificate according to DVGW and KTW — different kinds of cables — different kinds of seal materials

The DCT 533P is suitable for food / beverage and pharmaceutical industry as well as, for applications where a totally flush pressure port is required. The special design prevents condensation inside the pressure transmitter and thus a failure in applications with large temperature changes. The integrated, standardised IO-Link interface increases productivity and supports the operator in service and maintenance. Properties can be read and qualified via IO-Link, which helps the user to assess the state of system or process. Features: — nom. pressure: 0 ... 100 mbar up to 0 ... 40 bar — accuracy: 0.35% (opt. 0.25%) FSO — IO-Link acc. to specification V 1.1 — Data transfer 38.4 kBaud — Smart sensor profile — hygenic version — CIP / SIP cleaning up to 150 °C — ingress protection Ip 67 / IP 69 — diaphragm with low surface roughness Optional Features: — cooling element for media temp. up to 300 °C — different process connections

The sensor technology of the DCT 533 is the same as those of the proven pressure transmitter DMP 331 / DMP 333, whereby the DCT 533 is suitable for almost every industrial application, if medium is compatible with stainless steel 316L. The modular concept of the pressure transmitter allows customized electrical or mechanical connections, so it is easy to adapt the DCT 533 to different conditions on-site. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 400 bar — accuracy: 0,35 % (opt. 0,25%) FSO — IO-Link according to specification V 1.1 — Data transfer 38.4 kBaud — Smart sensor profile — perfect thermal behaviour — excellent long term stability Optional Features: — pressure port G 1/2" flush from 100 mbar — pressure sensor welded — customer specific versions
