DESCRIPTION

All components of the gas conditioning system are either housed in a compact stainless
steel housing or attached to it.
The sample gas line is connected directly to the heat exchanger inlet of the sample gas cooler. The
sample gas cooler cools the sample gas down to 5 °C [41 °F]. The heat exchanger is placed inside a
heat-insulated cooling block. An electronically controlled (analog technology) Peltier element cools
the cooling block to a constant temperature of +5 °C [41 °F]. A PT100 sensor is used to measure the
temperature. The thermal energy generated by the cooling system is dissipated via a fan-cooled
heat sink.
The cooler is equipped with a temperature alarm contact that switches off the sample gas pump in
case of a temperature deviation of ±3 °C [±5.4 °F] from the factory set point (+5 °C [41 °F]).
The peristaltic pump removes the accumulated condensate.
Downstream the cooler, there is a micro-filter with a 2 μm filter element and integrated liquid alarm
sensor LA. In case of leaking, the liquid alarm sensor switches off the sample gas pump
automatically.
A PTFE bellows pump is attached to the outside of the housing. This pump draws the sample gas
from the sampling point via the sample probe SP180H/MA (sold separately) through the heated
sample gas line (optional) into the cooler and further through the micro-filter. In the outlet of the
sample gas pump a flow meter FM40 with flow monitor FA-20mo is integrated. The flow rate monitor
FA-20mo signals the failure of the sample gas flow.
The now filtered and dried sample gas is passed on to the analyzer.
To calibrate the system, there is a switchover for test gas feeding through a solenoid valve. The
switchover is implemented in the gas treatment device.
