Parsum IPP 70-S
Malvern's newest sensor specifically designed to measure larger particles in many processes dealing with granulates, such as the chemical and food product industries, among others.

 

Real Time Sensor for measuring particles with an average size of 50-6000µm
 

  The probe can be easily installed directly into any gravity or pneumatic process line.
 
  Automatic feedback to central control room or terminal computer.
 
The sensor can be specifically modified to suit the process and material conditions by means of various accessories such as scavenging cells, a disperser and sampling systems. The IPP 70-S can thus be used in processes in which soiling or wetting of the optical window is likely to occur. It can be used with abrasive, slightly greasy, sticky and adherent particles, under high loads and at high temperatures.
Spatial Filter Velocimetry
Parsum measures particle size distributions using the accepted method of Spatial Filter Velocimetry


Process Interface
The Parsum is inserted directly in the process line so no sampling is needed.

Automation and control
Direct connection to upstream process control systems and monitoring of current production trends.


Solutions
The sensor has been used in a number of applications including the chemical and food industries.
 

A special range of accessories has been developed to expand the field of use of the IPP 70-S by adapting it to difficult process measurement conditions. The range of accessories is intended to provide constant protection of the measurement optical system against soiling, in-line thinning of dense particle flows, directional particle movement through the IPP 70-S sensor and decoupling from high process temperatures.

The accessories can easily be installed in the measurement chamber of an IPP 70-S. The components are operated by compressed air to create a constant curtain of scavenging air in front of the measurement optical system and for the carriage and thinning of the particle jet. The compressed air required is fed to the measurement chamber inside the IPP 70-S sensors and from there to the accessories.

The accessories include scavenging cells, dispersers, and the compressed air unit. The measurement chamber of the IPP 70-S must be fitted or combined with the appropriate sensor adapters, depending upon the process requirements.

There are several scavenger cells available to be used with IPP 70S.
