Door airtightness test chambers

The purpose of the test chamber is to measure the airtightness of doors which are in the frame of chamber at set pressure. Air is driven into the chamber with a ventilator which is controlled by an AC drive. The intake flow rate is measured by CS Instruments VA420 flow rate meter (0-480 m3/4). The pressure in chamber is measured with DPT series differential pressure transmitter. The temperature in chamber is measured in 11 points. All data is logged and visualized in logger and computer (via IGSS software).
