Dust detector VISGUARD OMD

flowmonitoringfor oil

The VisGuard measures the scattered light intensity of a sample drawn into the instrument. Filtered purge air is fed through the flow cell, thus enveloping the sample in a protective shroud of clean air. This effectively keeps the optics clean. Oil dust in the sample can be detected early to help preventing from further incidents. Continuous monitoring of oil mist concentration using scattered light principle Fully complying with the latest IMO code of practice for atmospheric oil mist detectors Easy to service, high sensitivity, stability and accuracy Nominal range 0 .. 100 PLA (Polystyrol-Latex-Aerosols) Sampletaking Extractive Scale ranges 0..0.1 / 0..0.3 / 0..1 / 0..3 / 0..10 / 0..30 / 0..100 PLA Protection index IP65 Sample temperature -20 .. +50 °C Sample pressure max. ±3'000 Pa (±30 mbar) Interfaces RS232, Modbus, Profibus DP 0/4 .. 20 mA relay contacts Control unit Ambient environment Temperature range -20 .. +50°C 0 .. 100% r.h.
