Detection of Particle Sizes Ranging from 0.5 to 8000 µm

In the development of new sensor technologies, PAMAS (Germany) fulfills current market demands and application inquiries. Customers in the industries such as pharmaceutical, oil, automotive and filter market for instance have a high demand for particle counters that are able to detect particle sizes smaller than 3 µm(c). From 1992 until 2008, PAMAS’ particle sensors worked with the principle of light extinction. These sensors do have a broad detection interval and are able to reliably detect and measure particle sizes up to 8000 µm.

As a consequence, light extinction sensors are the ideal equipment for the analysis of high viscous and highly contaminated liquids. However, liquid particle counters are also used for the detection of smaller particle sizes. Due to the increasing demand for the measurement of smaller particle sizes, PAMAS developed in 2008 a sensor working with light scattering technology that is able to reliably detect particle sizes down to 0.5 µm. Since 2009, PAMAS has been successfully installing the new sensor into the particle counter models PAMAS 4132, PAMAS S40 GO, PAMAS S4031 GO, PAMAS SBSS and PAMAS SVSS. The Scattered Light Sensor PAMAS SLS-25/25 measures particle sizes ranging from 0.5 to 20 µm (according to the calibration standard ISO 21501) and from 1.5 to 30 µm(c) (according to the calibration standard ISO 11171).
