ENDRESS+HAUSER  CAT820-AAE11A2A100A

Automatic sample conditioning system for supplying process measuring devices with filtered sample from sludge activation, secondary clarification or surface water

Control of sample conditioning by means of the Liquiline System CA80 or a time control system

Application

Liquiline System CAT820 enables the fully automatic collection and filtration of aqueous samples. Thanks to the modular concept, the sample preparation system can be adapted to various different process conditions. There are various filters and hose lengths available for this purpose. For installing the filter in the process medium, various assemblies are available as accessories. The heated version of the hoses and of the housing mean that the system can be used at temperatures as low as -20 C.

The device is designed for use in the following applications:

• Communal and industrial wastewater treatment plants
• Surface waters
• Collection of aqueous samples from industrial processes

Your benefits

• Robust and reliable:
  • Peristaltic pump, sampling takes place free from interference
  • Optional compressed air cleaning system
  • Optional hose and housing heating system
• Simple and user-friendly:
  • Control via a CA80 analyzer
  • Alternatively via a time control function
  • Installation compatible with existing holders
• Cleaning and maintenance: Replacement of pump hoses and filter without using tools
• Flexible:
  • Modular filter system
  • Accessories for a range of installation conditions

Function

A peristaltic pump is used to take the sample. The sample is drawn in via the filter element, filtered and fed to the analyzer. An optional cleaning valve enables backflushing of the filter unit with compressed air.
