ILMK 8 Stainless Steel Probe Ceramic Sensor accuracy according to IEC 60770: standard: 0.5 % FSO option: 0.5 % FSO Nominal pressure from 0... 40 cmh O up to 0... 00 mh O Output signals -wire: 4... 0 ma -wire: 0 0 V others on request Special characteristics diameter 9.5 mm especially for sewage, viscous and pasty media Optional versions IS-protection zone 0 mounting with stainless steel pipe flange version diaphragm 99.9 % AI O different kinds of cables different kinds of elastomers The stainless steel probe ILMK8 has been designed for continous level measurement in waste water, waste and higher viscosity media. Basic element is a robust and high overpressure capable capacitive ceramic sensor e.g. for low levels easily. Preferred areas of use are Water drinking water abstraction Sewage waste water treatment water recycling Fuel / Oil level monitoring in open tanks with low filling heights fuel storage tank farms / biogas plants D-656 Hohen Neuendorf / OT Bergfelde
