Compact, lightweight and easy to install, the Parsum IPP-70-S probe delivers in situ, real-time size and velocity measurements for solid particles up to 6000 µm in size. Dustproof and waterproof, and requiring no sampling or calibration, it provides continuous process monitoring at high and fluctuating solids loadings, even for abrasive, greasy or sticky particles.
Parsum IPP 70-S is the standard instrument option. Used in the chemical, food and pharmaceutical industries for endpoint detection, process control/optimization and real-time QC, it is applied in unit operations such as grinding, agglomeration, granulation, sieving and spray drying.
Lightweight and easy to install for rapid integration into new and existing processing plant
Wide dynamic range for particles from 50 - 6000µm travelling at up to 50m/s
Reproducible measurement at high solids loadings even with irregularly moving particles - ideal for fluidized bed monitoring
Real-time measurement and feedback via comprehensive, customizable software
No sampling or calibration required
Range of accessories enables application for abrasive, greasy, sticky and adherent particles

The D24 disperser dilutes and disperses material drawn from the process, simultaneously directing it towards the measurement zone of the Parsum probe. It ensures robust and accurate sizing for particles with a Dv50 in the range 50 µm to 1.2mm, making it especially useful for direct measurement within fluidized beds.
The D12 sample disperser samples, dilutes and disperses material from a process, simultaneously presenting it for accurate particle size distribution and velocity measurement using the Parsum inline measurement probes. It ensures robust and accurate sizing for coarse particles in processes where solids loadings are high, such as within granulation systems.
Used in combination with Parsum IPP70-S or IPP70-SE probes, the at-line measurement station enables fast, efficient particle sizing of process samples in the laboratory or on the plant.
Parsum’s optional 4-20 mA interface board streamlines the transfer of particle size data from the probe to a centralized control system, for automation or data display. Eight channels allow interfacing with four probes, each installed as far as 100 m away from the analyzer PC.
The Parsum IPP 70-S probe uses the well-established measurement principle of spatial filter velocimetry. No calibration or sampling is required and there is no assumption that the particles are spherical.
Spatial filter velocimetry is a number-based, chord length sizing method that collects data for individual particles to develop a particle size distribution.
Particles falling through a laser beam cast a shadow, interrupting the flow of light to a linear detector array made up of optical fibers. Particle velocity is calculated from the sequential interruption of linearly neighboring fiber elements of the spatial filter detector.
Particle size is determined using a secondary signal, the pulse signal, which is a measure of the length of time for which the particle blocks a single optical fiber.
Measuring a large number of particles generates statistically valid results from which various size parameters and volume-based distributions are derived, depending on the needs of the user.
The Parsum IPP 70-S is installed directly into the line or vessel. Although no sample preparation is required, an internal compressed air supply can be used to disperse agglomerates, to keep the flow channel and optics clear of adherent material and to enable measurement at high solids loadings and temperatures.
Information is transferred from the measurement zone to the electronic housing of the probe via fiber optic cable increasing instrument robustness. These data can then be transferred to the control room or indeed into an existing control system for processing monitoring and control. Because the instrument provides a measure of concentration in the sensing volume, changes in flow/throughput can be estimated, using an appropriate correlation.
