Trace detector OILGUARD 2 EX

UVfor oilcompact

Oil Trace Monitor for Mineral Oils for hazardous Areas The OilGuard works on the fluorescence principle. The design uses a free-fall measuring system that eliminates contact between the sample and the flow cell. Adoptions to various types of oil are carried out by means of calibration curves, a control glass makes it easy to check or recalibrate the instrument. A pressurized-enclosure version is offered for areas requiring explosion protection. Well-proven UV-Fluorescence measuring principle True non-contact measurement in a free-fall stream Dual-beam optics for highest accuracy and stability Measuring principle UV-Fluorescence Nominal range 0 .. 100 FLU 0 .. 1'000 ppm oil (depending on the oil characteristics) Scale ranges 8, freely configurable Resolution ±0.5% (referred to quinine sulphate in water) Reproducibility ±2% (referred to quinine sulphate in water) Reaction time limit switch) Installation Online side stream Enclosure Stainless steel 316L / 1.4404 Protection class Ex px IIC T4 Gb Protection index IP66 Flow cell material Closed flow cell: stainless steel 316L / 1.4435 Free-fall cell: stainless steel 316L / 1.4435 or PVDF Sample flow rate Closed flow cell: 0.5 .. 2 l/min Free-fall cell: 5 .. 7 l/min Sample temperature Closed flow cell: max. 100 °C Free-fall cell: max. 40 °C (VA), max. 95 °C (PVDF)
