Introduction to the Instrument 1-47

3UHVVXUH6HQVRU

The pressure sensor is used to measure the ambient pressure during the auto zero process and

to measure the pressure in the measurement cell during measurement mode.

$QDORJ6HFWLRQ

The analog section amplifies and digitizes the main, reference, pressure and temperature

signals.

&RQWUROOHUDQG3HULSKHUDOV

The controller reads the digitized values from the analog section and calculates the CO

wave

and numerics based on the measured main, reference, pressure and temperature signals. The

controller also controls the CO

frontend based on the control information received from the

Measurement Server, the Optical Code Recognition and the measured cell pressure.

The gas inlet allows the connection of Microstream FilterLines. The Microstream FilteLines

are detected by the Optical Code Recognition.

The Serial Interface and Frontend Link Protocol (FELP) provide the communication

interface between the CO

frontend and the CO

application software module running on the

main CPU of the Measurement Server.
