Drastically reduced emission limits call for increased measurement accuracy of particulate mass results. AVL’s solution to these new challenges is the Filter Weighing Chamber (FWC). It is a cost- and space-saving alternative to a separately conditioned clean room and offers maximum user friendliness, ergonomics and functionality. The AVL Filter Weighing Robot (FWR) automates the weighing process from conditioning to filter disposal and archiving (from 160 to 640 filters). Thus, it reduces measurement inaccuracy and increases the efficiency of the entire weighing process. MEASUREMENT PRINCIPLE A laminar flow with a precise monitoring of temperature and dew point is assured within the working area. In addition, the atmospheric pressure is monitored and is ready to be used for the required buoyancy correction. The ambient air inserted into the working area is prepared to achieve the clean room standard 5 according to ISO 14644-1. A vibration-decoupled weighing stone is situated in the weighing section. The high-precision scale is place on this stone. Throughout the whole weighing process, automated by the AVL FWR, the filter stays in a RFID transport ring with integrated RFID chip. Thereby, any filter data can be stored and read anytime. No moving of the filters or handling with foreceps is necessary. APPLICATION The AVL FWC is ideally suited for installation in laboratory and testbed environments for particle filter weighing. The working area offers sufficient space for handling and storage of the particle filters. The AVL FWR is used and controlled by means of AVL ParticleScale for the measurement of very low particulate masses.
