PAMAS 4132

Description

Online Particle Counter for Filter Test Rigs

Single Pass and Multipass filter efficiency analysis

The particle counting system PAMAS 4132 analyses liquids of various viscosity degrees (e.g. oil, fuel, water, etc.). The system is adaptable to any Multipass application and ß-ratio analysis.

In case of a Single Pass Filter Test, the liquid passes the filter only once and then is deviated to the outflow. For ß-ratio-analyses, the Single Pass Filter Test can be performed with two PAMAS 4132 instruments.

Two PAMAS 4132 instruments – equipped with 32 size channels each – are also used for the Multipass Filter Test. This test rig with two particle counters allows simultaneous upstream and downstream measurements. For the Multipass Filter Test, the liquid flows continuously through the system.

  • Analysis of high concentration levels in ß-ratio applications
  • High resolution analysis in 32 size channels
  • Sensors can handle high pressures
  • Remotely adjustable thresholds
  • Different sensors for various applications

Due to the volumetric cell design of PAMAS particle sensors, 100% of the sample flow volume is analysed this guarantee highest volume accuracy and reproducibility and best statistical information:

  • Coincidence error rate less than 7.8%
  • 1,5 µm(c) sensitivity according to ISO 11171
  • 1 µm sensitivity according to ISO 4402
  • 0,5 µm sensitivity according to ISO 21501
