ERD620 – LEAK TESTER FOR HIGH VOLUME PRODUCTION PRODUCTION BATTERY POUCH CELL TESTING
On the basis of its well proven concept of production line QC Testers, ATEQ has developed a new leak tester designed for the specific requirements of high volume production of plastic parts. This instrument is used for the detection of localized moulding faults, insufficient membrane thickness, perforations, etc. This instrument has also proven to be effective on testing pouch battery cells.
The ERD620 is based on discharge current measurement and is able to detect defects up to of 10µm.

ERD620 : TECHNOLOGY
Sometimes a leak can be considered as a “small flow”, or a flow as a “big leak”. When your reject level is too high for other technologies, it may be necessary to use a laminar flow tester. A flow takes place between the pressure line and the leak hole of the part.
Our instrument features a laminar flow element across which our differential pressure transducer is connected.
Every flow generates a pressure difference between the inlet and outlet of the laminar flow element, and this variation is measured by the pressure transducer.
When the fluid (gas) enters the device 1, it moves through a calibrated flow tube 2 which causes a drop in pressure. The pressure drop is measured by a differential pressure sensor 3. The pressure of the part under test 5 is measured by the sensor 4.
