Key Features

ISO
CompliantFully compliant with ISO, providing both standard method and refined methodology

Real-Time ReportingReal-Time Reporting: Particle number and size distribution across all 8 size channels are reported in real time to a PC or PLC. The optional analysing software saves measuring results and displays them in tables and graphs, making trends and events easily visible

High
PrecisionHigh Precision: The volumetric cell design of the sensors measures 100% of the sample flow, guaranteeing the highest accuracy and reproducibility, with a fast screening test program available for unknown samples

Straightforward OperationStraightforward Operation: An intuitive menu structure ensures seamless user navigation, including a convenient and easy-to-follow navigator for calibration

Rugged
ConstructionRugged Construction: Measures the cleanliness of mineral and synthetic oils in a range of industrial environments, with a rugged construction that resists mechanical, environmental and electrical threats

Trend
MonitoringTrend Monitoring: Accuracy combined with trend monitoring and alarm features reduces the risk of failures and supports the reliability of the controlled operating system
The PAMAS S50 is a cost-effective, high-performance, laser-based online particle monitoring system with simple integration into industrial data management systems. Fully compliant with methods ISO 4406 AND ISO 11171, PAMAS S50 measures the cleanliness of mineral and synthetic oils in different industrial environments. Its rugged construction makes it resistant against mechanical, environmental and electrical threats.
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 m(c), > 6 m(c) and > 14 m(c) is indicated on the instrument display.
More than just providing the standard ISO code, PAMAS S50 is cost-effective and measures the particle number in eight different channels while giving early alerts. Also, it may serve as an interface for condition monitoring transferring four analog signals (4-20 mA) to a PC.
The PAMAS S50P is anadditional option to the online particle counter, with an integrated pump for flow control to a constant flow of 25 ml/min.
