The two versions of the GPP differ with regard to the respective filter making them suitable
for different applications,
see page 17.
Advantages of GPP
probes
GPP probes do not require a purge air supply and are easy to maintain. They are fitted with
an automatic heater for reliable prevention of condensate on the optical interfaces. The
electronic components for the heater regulator, and temperature and pressure
measurements, are located protected in a stable cast housing which forms the measuring
probe section between the duct flange and the SR-unit.
The Figure below shows this housing fitted with the electrical connections for the CAN bus
and power supply as well as the test gas connection which supports audit measurement
according to EPA Directive CFR 40, Part 60 or Part 75.
