IN THE WORLD OF PARTICLES PAMAS COUNTS REV 01/2023

QUALITY POLICY GLOBAL PLAYER Our findings not only feed into our products. We also make our expertise available to numerous standardization committees and other industry bodies to develop standards where we are actively contributing. Founded in 1992 PAMAS is a private, self financed, independent company that has sustained solid responsible growth through its own efforts. We are committed to complying with all legal requirements. PAMAS Partikelmess- und Analysesysteme GmbH is based near Stuttgart Germany. We develop, produce and sell highquality devices for particle measuring and analysis. A largely...

In hydraulic and lubricating oil systems, particle counters are used for oil contamination analysis. Permanent condition monitoring of hydraulic and lubrication oil systems is a pre-requisite for continuous operation: Preventive analysis methods make a future need of repair and maintenance predictable. The portable particle counters of the PAMAS S40 product series can be used for batch and online sampling and for on-site measurements. With the aid of pressure reducer devices, the particle counters are adapted to sample fluid viscosity and to environmental pressure. The customer hence gets a tailor-made...

HEAVY EARTH MOVING MACHINERY For the purpose of preventive and proactive maintenance, automatic particle counters are used to control the cleanliness of hydraulic fluids. Hydraulic fluids are used for power and energy transmission in fluid power systems. The pressurised fluid transfers energy from a pump to a power machine. The quality of hydraulic fluids mostly is adapted to the application type. In aviation, fluid power is done with hardly inflammable fluids. In the offshore sector however, environmentally friendly hydraulic fluids on water basis are preferred, as they are biodegradable and...

FUEL ANALYSIS Fuel is less viscous than oil. In low viscous fluids, the particles slump down in the liquid and build a sediment at the bottom of the bottle (sedimentation). Individual particles might also stick together during storage and become agglomerated bigger particles (agglomeration). Before a sample can be analysed via laboratory measurement instruments, it needs to be prepared with applied mechanical energy to redisperse the particles in the liquid. Before undertaking laboratory particle analyses, the sample thus must be adequately prepared for measurement. In case of online measurement,...

AVIATION HYDRAULICS The cleanliness control of hydraulic fluids is a typical application of optical particle counting with the aid of an Automatic Particle Counter. Hydraulic fluids are used for the transfer of energy in hydraulic systems. For smooth operation and uninterrupted maintenance of functionality, it is essential that the operating liquid is regularly controlled; a high degree of contamination could cause a malfunction within a component and may also lead to a complete system break-down. Different types of hydraulic fluids are used for different types of application. The three main...

For safety and ecologic reasons, hydraulic systems in the offshore Oil&Gas industry are operated with biodegradable hydraulic liquids. These water-glycols cause less harm than oil based hydraulic fluids if they accidentally flow into sea water. Water based fluids are also preferred because of their stable viscosity degree regardless oscillating temperature. Furthermore, they are fire resisting and hardly inflammable. Water based hydraulic fluids are used in the following offshore applications: Subsea Christmas Trees and Wellhead Assemblies, Hydraulic Power Units, Hydraulic Accumulators, Subsea...

For the particle analysis of pharmaceutical fluids, PAMAS provides two laboratory instruments with different options and equipment. Due to this variety, the user is able to select the ideal particle analysing system for the individual fluid and the specific application. The analysing instrument PAMAS SVSS (Small Volume Syringe System) is designed for the analysis of low viscous fluids including infusion solutions, parenterals, pharmaceutical suspensions and intravenous or ophthalmic liquids. For higher viscosity samples or for fluids containing gas bubbles, PAMAS offers the measuring instrument...

Filter efficiency testing is another application field of Automatic Particle Counters. The performance of a filter depends on its efficiency and its retention grade: A good filter retains solid particles more efficiently than a filter of low quality. There are various standardised test methods to determine the characteristics and quality of a filter. These methods mostly refer to the specific conditions dependent on the industry sector (e.g. test methods for water filters or for hydraulic filters). The Multi Pass Filter Test is standardised by ISO 16889. Its performance can be greatly improved...

There are various existing methods to determine whether water is clean and free from particulate contamination. In water treatment systems, both particle counters and turbidimeters or nephelometers are used for water quality control. Whereas turbidimetres and nephelometres indicate the degree of turbidity which is caused by the particle contamination, an Automatic Particle Counter detects every single particle that passes the sensor cell during measurement. The knowledge of the particle sizes is of paramount importance in water applications, as it helps to quickly identify certain types of bacteria...

FLUID PARTICLE COUNTING The German company PAMAS develops, manufactures and sells Automatic Particle Counters for fluid cleanliness control. The advanced and highly sophisticated sensor technology enables the detection of particle sizes down to 0.5 microns. Particle measuring technology is used to control cleanliness of liquids and to identify quality deficiencies and excessive wear in order to avoid eventual costly machine failures. It is impossible to detect particles in liquids and to analyse the actual level of contamination with the naked eye. A variety of analysing technologies can be used...
