Der tragbare Partikelzähler PAMAS S40 misst den Verschmutzungsgrad von Flüssigkeiten online oder offline. Für eine Onlinemessung wird das Gerät an ein laufendes System angeschlossen, wo es die Reinheitskontrolle der Betriebsflüssigkeit (z.B. Hydrauliköl) direkt vor Ort vornimmt. Offlinemessungen aus Probenflaschen sind ebenfalls möglich. Der Partikelzähler ist in zahlreichen Produktvarianten für die Analyse von Öl, Treibstoff, Skydrol® oder wasserbasierte Flüssigkeiten erhältlich.

For online sampling, the instrument is integrated into a system in operation, so the operating fluid (e.g. hydraulic oil) can be analysed directly on site. Batch sampling out of bottles is also possible with the PAMAS S40. There are various product versions of this particle counter available for the cleanliness control of oil, fuel, Skydrol® or water based fluids. (Picture: PAMAS)

On June 1st 2017, PAMAS is going to celebrate its 25th anniversary. The company develops and manufactures automatic particle counters for fluid contamination control. The PAMAS product range includes measuring instruments for the cleanliness control of hydraulic or lubricating oil, water, fuel and pharmaceutical liquids. Due to their versatility, the portable particle counters of the PAMAS S40 product series are well established in various markets and applications. PAMAS will be exhibiting its particle counting instruments at the Motion, Drive & Automation show, taking place within Hanover fair in April 2017 (Booth No. A47 in Hall 23).

Online and offline, pressureless or under high pressure, in the laboratory or in the field – the versatility of PAMAS particle counters is evident and typifies how over the years, the continued developments have ensured that PAMAS remains a world leader in liquid particle counting. PAMAS has been manufacturing automatic particle counters for fluids for a quarter of a century. With the aid of these compact and convenient instruments, the user knows within minutes if and to what extent a sample fluid is contaminated. The particle analysis technique is based on an optical measuring principle; light sensors are used to detect and count contaminants in a liquid. Over the course of the last 25 years, PAMAS has been perfecting this technique and implementing additional options and features. An example of this versatility of PAMAS particle counters is in the PAMAS S40 product series.

In addition to standard particle counting of sample bottles in a laboratory, the PAMAS S40 particle counter can also be used for online sampling. For online measurements in the field, the particle counter is integrated into a system in operation (e.g. an ongoing hydraulic or lubricating oil system). A sample of the operating fluid is extracted out of the system via a bypass valve and drawn into the particle counter. With this method, the user can verify in-situ if the sample meets or exceeds the pre-defined contamination cleanliness level.

Pressurised fluids and harsh environments do not affect the particle analysis with a PAMAS S40: Due to an integrated pressure reducer, fluids can be measured under high pressure. For particle counting in the field, PAMAS instruments are available in a rugged case that protects from harsh environment.

Practical orientation and a close cooperation with the end user turned out to be of great benefit for the development of PAMAS particle counters: Together with the end user, PAMAS began to develop individual solutions for their specific application. For an Aviation customer who wanted to analyse a corrosive hydraulic fluid, PAMAS developers built a particle counting system out of chemically stable components. The material was not affected by the corrosive sample liquid. This specific solution matured into a new PAMAS S40 product version which has been tried and tested for other applications with corrosive liquids and is available as part of our product versions.

Further product versions of the PAMAS S40 have been developed for Jetfuel and for water based hydraulic fluids that are mainly used in the Oil&Gas sector. For these applications, the particle counting results were brought into the industry-related format which is commonly used within these industries, so the user does not need any further software to convert the results. For users in the Oil&Gas sector, the particle measuring results are reported according to the SAE AS 4059 or NAS 1638 standards, and for users in Russia or China as per GOST 17216 or GJB 420.

After 25 years of research and development, the portable particle counters of the PAMAS S40 product series are now available in a multitude of adapted product versions for the cleanliness control of oil, fuel, Skydrol® and water based fluids.
