Residual oil measurement in compressed air systems

To ensure the quality of compressed air, it isabsolute 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 or semiconductor manufacturing.
The residual oil plays an important role especially 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. The effort of cleaning of pipe network choked with oil can lead to very high costs.
An oil outbreak is often detected very late, normally only when quality problems have already appeared and large damages is caused. Therefore, the high quality requirements in the industry require a continuous residual oil monitoring, that is reliable and provides long term stable service. This is the only way to detect problems before the damage occurs.
The RCS OIL MONITOR with its calibrated measuring range of 0.01 … 5 mg/m3 is the ideal measuring system for monitoring of compressed air plants. The device is meant for stationary applications.

The RCS OIL MONITOR is a stationary air monitoring system specially developed for monitoring of organic and inorganic gas impurities as well as gaseous hydrocarbons in compressed air systems.

The RCS OIL MONITOR can be used to monitor the maximum allowable total oil content according to ISO 8573-5. The integrated electronics and compact design enables detection of residual oil content in compressed air systems in a real-time method, without the usual diversion through physical-chemical analysis. Hence, the production processes and machines can be protected round the clock.

The RCS OIL MONITOR has a measured value display at which the user can read the current condition of the plant. The display of material concentration is in ppm or mg/m3 at standard conditions. The user is provided with a pre-alarm and a main alarm. The device raises an alarm if the readings are outside the tolerance limits. Through a switch-able median value filter and configurable alarm delay, the RCS OIL MONITOR can be configured to ignore short-term fluctuations of values in the system, in order to avoid false alarm and unnecessary interruption of the process. An RS 485 serial interface as well as a 4 ...  20 mA current loop output is available for integration into superordinate system.
