Oil contamination can affect compressed air processing systems in many different ways, posing a danger to the safety of workers, the environment and the production equipment. Monitoring systems such as the METPOINT OCV compact continuously control the compressed air accurately and according to applicable standards for the residual oil vapour concentration . You therefore retain the compressed air quality.
The METPOINT OCV compact has been developed for measuring hydrocarbon vapours and gases in compressed air system applications. The detection levels are as low as one thousandth mg/m³ of residual oil vapour content and are executed continuously in ongoing operation. Shortened measuring intervals enable the rapid and reliable display of even the smallest deviations. This on-line monitoring process provides the certainty about the quality of your compressed air as an important element of your process safety at all times and at all quality-critical system points. The measurement data can be utilised for documenting the compressed air quality and for identifying contamination sources.
The METPOINT OCV compact provides information about the current measurement value (oil vapour in mg/m³), the ISO 8573 oil class as well as the status of the measuring system and its components. In addition, the status of the measuring cell and the reference gas generation (purificator) will be displayed visually. You therefore always have an overview about the measurement values, oil class, system status at all times and know immediately that your compressed air is correct.
In the METPOINT OCV compact system, a PID sensor works according to the principle of photo-ionization using a UV lamp. To increase the precision and to compensate for the smallest fluctuations, the determined values are temperature and pressure compensated. This fulfills the requirements of ISO 8573. As a continuous self-control of the measuring system, a reference gas generated by means of an integrated catalytic converter is used. In the periodic change between measuring air and reference air, the function of the PID measuring cell is continuously controlled and adjusted.
