COMPRESSED AIR QUALITY MEASUREMENT

to ensure the quality of compressed air, it is absolute necessary to monitor the important parameters. apart from dew point as a critical dimension, the residual oil content plays a vital role. many production processes depend on clean, treated compressed air without traces of hydrocarbons, for example, in pharmacy, chemical industry, food industry or semiconductor manufacturing.

the residual oil plays an important role specially in the distribution mechanisms. if the oil content rises over the critical level, for example, because of incomplete filtered aerosol, the complete plant gets contaminated in a very short time. since the oil has a very low vapour pressure, it takes relatively long time to bring back the plant to completely „oil free“ condition. moreover, the cleaning of pipe network choked with oil causes very high costs

however, oil ingress is often detected very late, usually only when already quality problems have started coming up and huge damages have occurred. therefore, the high quality standards in the industry require a continuous residual oil monitoring, which performs in a reliable and long-term stable manner. only then the problems can be detected early before they cause damages.

oilguardPRO constantly monitors – with a measuring range of 0,001 - 20 mg/m3 – the residual oil content and in turn the quality of compressed air to avoid contamination in the plant because of hydrocarbons; a specially developed metal oxide sensor constantly detects any deviation from standard value and gives an indication.

the measured value can be easily passed on further through a 4 - 20 mA-output as well as potential free contacts to externally connected components (control, transducer, etc.) and can be graphically represented with the help of an optionally available software.
