DCT 533P

The pressure transmitter DCT 553P is used in the food and pharmaceutical industries or in applications where a dead space-free process connection is required. A capacitive ceramic pressure sensor developed in-house is used as the basic sensor, which is characterized by a high overload and excellent surface quality. The special design prevents the formation of condensation inside the pressure transmitter and thus failure in applications with large temperature changes. The integrated, standardised IO-Link interface increases productivity and supports the operator in service and maintenance. Features: — nominal pressure: 0 ... 40 mbar up to 0 ... 20 bar — accuracy: 0.35% (opt. 0.25%) FSO — IO-Link acc. to specification V1.1 — Data transfer 38.4 kBaud — Smart sensor profile — hygienic version — protection IP 67/ IP 69 — high overpressure resistance — diaphragm ceramics Al2O3 (99.9 %) Optional: — different process connections

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 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. 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. The outside-diameter is only 22 mm for easy installation and back fitting in 1″ tubes or in cramped fitting conditions Features — Nominal pressure from 0 ... 1 mH2O up to 0 ... 100 mH2O — accuracy: 0.35% (opt. 0.35 %) FSO — output signal: RS485 with Modbus RTU protocol — diameter 22 mm — highly appropriated for sewage water Optional features — drinking water certificate according to DVGW and KTW

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
