ONLINE PARTICLE COUNTER FOR OIL CONDITION MONITORING PAMAS S50

The PAMAS S50 is a cost-effective, high-performance, laser-based online system with simple integration into industrial data management systems. An automatic digital flow rate determination provides accurate measurement results. The PAMAS S50 counts particles with high resolution in eight particle size channels, available via the data interface for report in real time to the PC. The triple code according to the cleanliness class standard ISO 4406 for the particle sizes > 4 µm(c), > 6 µm(c) and > 14 µm(c) is indicated on the instrument display.
