Parsum IPP 80-P

An intrinsically safe inline particle sizing probe for real-time measurement in pharmaceutical and food applications

Specifically designed for the pharmaceutical and food industries, the Parsum IPP80 is an intrinsically safe probe delivering real-time particle size and particle velocity measurements for solid particles in the range from 50µm up to 6mm in size. Its simple, dustproof and waterproof probe design enables direct monitoring of fluidized bed and high shear mixing and granulation processes.

The Parsum IPP 80 is used in food and pharmaceutical applications for endpoint detection in batch granulation process, and for real time monitoring of continuous manufacturing processes. It is applied in unit operations such as grinding, agglomeration, granulation, coating and sieving.

  • Compact, lightweight and easy to install for rapid integration into new and existing processing plants 
  • Characterizes particles in the range from 50 µm to 6mm, travelling at up to 50 m/s 
  • Reproducible measurement at high solids loadings enabling real time fluidized bed monitoring 
  • Real-time measurement and feedback via comprehensive, customizable software
  • Measurements can be carried out without the need for sample extraction 
  • A range of accessories enables measurements to be made for abrasive, sticky and cohesive particles 
  • complies with ATEX requirements for operation within Zones 0 and 20.

How it works

The Parsum probe uses the measurement principle of spatial filter velocimetry. This is a number-based, chord length sizing method that collects data for individual particles to obtain a particle size distribution and velocity distribution.


Particles falling through the Parsum probe measurement zone block the light emitted from a laser light source. The resulting shadow is detected using a linear detector array made up of optical fibers. Particle velocity is calculated by tracking movement of the particle shadow across sequential detector elements. Particle size is determined by measuring the length of time 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.

The Parsum probe is installed directly into the process 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 material and to enable measurement at high solids loadings.

Information is transferred from the measurement zone to the electronic housing of the probe via fiber optic cable, increasing instrument robustness. A direct cable connection of up to 100m in length can then be used between the probe and the computer, enabling operation of the system from a safe area. Results can be reported to a PCL via 4-20mA signals or using OPC or TCP servers to a plant control system.

D24 inline sample disperser

Inline disperser for fine particle processes

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.

D12 inline sample disperser

Inline dispersion for coarse particles and high solids loadings.

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.
