The hydrostatic probe LMK 487 has been developed for measuring levels in various tankm applications for shipbuilding and offshore. In comparison to the hydrostatic probe LMK 458 the external diameter amounts to only 22 mm by which the installation in 1" pipes can be carried out easily. Beside the housing materials stainless steel and titanium, different elastomer materials are available by which an optimum adaptation to the application can be ensured. Features: — nominal pressure: 0 ... 1 mH2O up to 0 ... 100 mH2O — accuracy: 0.25 % FSO — output signal 4 ... 20mA / 2-wire — diameter 22 mm — shipping approvals: ABS, LR, DNV, GL, CCS — high long term stability — diaphragm ceramics Al2O3 (99.9 %) Optional Features — IS-version Ex ia = intrinsically safe for gases and dusts — housing material titanium — temperature element Pt 100 — different kinds of elastomer

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
