Properties
Application
The heated gas sampling probes PSG Basic Probe are used for continuous extractive gas analysis. They enable continuously trouble-free representative sampling of hot, predominantly low or medium dust and water vapor loaded gases – high dust load with additional options. Typical applications are emission measurement, process monitoring, control and optimization.

Technology
he intelligent design with optimum gas guidance enables the filtration of sample gas at the outer 212 cm2 filtration surface (largest worldwide) as well as quick and easy filter change without tools and dismounting of the heated sample line. Easy maintenance of the PSG Basic Probe is enabled due to its newly space-saving bracket design, which also can be used to lift a sticking filter housing lid. The holohedral tight high- performance ring heater in combination with the tight thick-walled glass fiber insulation jacket ensures a homogeneous heating of the complete PSG Basic Probe up to 250 °C. The self-regulated version has a factory setting of 160 °C (standard) up to 180 °C. Regulated temperature enables up to 250 °C and is recommended especially in case of high (acid) dew point or to avoid salification (especially if sample gas includes low acidic / alkaline components as NH3 leading to ammonium carbonate): Sophisticated PSG Basic Probe design – long lifetime.
Functions
Extreme large filter surface & homogeneous heating ensures that dust will always be separated reliably in the PSG Basic Probe without condensation of water vapor thus avoiding blocking of the filter. Due to large filters with 0.1 resp. 0.3 µm porosity the PSG Basic Probe can be used for applications with up to 3 g/m3 dust and 10 g/m3 with pre-filter or single stage back purge. The 0.3 µm surface coated SiC ceramic filter enables best thermal & chemical resistance also for tough applications. The standard calibration resp. test gas connection enables the use of the PSG Basic Probe within emission monitoring systems acc. to EU Regulations 2000/76/EG & 2001/80/EG: TI Air (TA Luft), 13th & 17th BImSchV (large combustion plants, waste incineration). PSG Basic Probe design allow small, medium or high dust contents.
