firmware is implemented with microcontrollers, which are located on separate electronic
boards so parallel real time data processing is possible.
ETHERNET CONNECTOR
The Ethernet connector allows the connection of the AE33 measurement system to Ethernet
based communication networks.
COM1, COM2, COM3 CONNECTORS
The COM connectors allow the connection of the system to RS232 based devices, like external
sensors or dataloggers.
USB CONNECTOR
The USB connector allows the connection of the system to USB based devices, like external
sensors or data processing units.
AIR INLET and OUTLET CONNECTORS
The air inlet and outlet connector allows the connection of the instrument to external airflow
system. The measured air enters the instrument through the inlet connector and leaves the
instrument through the outlet connector.
BALL VALVE
The ball valve is an electrically actuated valve which is connected directly to the inlet
connector and connects or separates the instrument from the external air system.
MUFFLER
The muffler (CRC filter) is used to decrease the noise in the airflow which is created by
mechanical rotation of the pump.
