Parsum IPP 70-SE
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 IPP 70-SE is an intrinsically safe unit. Its low power input allows for its implementation in hazardous areas. The probe can be used in Ex-Zones 0 and 20, e.g. in pipes/systems of the chemical industry. Due to zone separation the corresponding electronics casing may be used in Ex-Zones 1 and 21.
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.
