Apparatus and measuring device for determining the particle concentration, the particle size, the average particle size and the particle size distribution of the particles of a dispersed phase within a disperse system as well as its turbidity

摘要

The invention relates to a device and a measuring arrangement for determining the particle concentration, the particle size, the average particle size and the particle size distribution of the particles of a dispersed phase within a disperse system (2) as well as its opacity by measurement of the transmission and / or by measurement of the scattered light (4 '') of a measuring beam (4, 20, 27, 30) after a in the disperse system extending measuring section (l, l1, l2). The device has a flow chamber (1), which the disperse system (2), a measuring beam penetration surface (6), from which the measuring beam (4, 20, 27, 30), and a measuring beam collector surface (10), the measuring beam (4, 20, 27, 30) after passing through the measuring section (l, l1, l2) receives. According to the invention, there extends a first outer element (7) of the measuring beam penetration surface (6) and a second outer element (11) of the measuring beam collector surface (10), in each case for or in the flow chamber (1) and. In this case, the ends of the first and second sheath element (7, 11) arranged in an axial distance from one another and the measuring beam (4, 20, 27, 30) within the first and second sheath element (7, 11), whereby the section of the measurement beam (4, 20, 27, 30) between the ends of the enveloping elements (7, 11) the measuring path (l, l1, l2) defined. In this way, the measuring beam penetration surface (6) and measuring beam collector surfaces (10) is kept free of deposits, so that accurate ..
