Combustion product sensing devices for gas burners and gas burning appliances
This European Standard specifies the safety, construction and performance requirements for combustion product sensing devices intended to be used in combustion control systems, hereinafter referred to as CPSD.
This European Standard applies to sensing devices for the measurement of combustion products from burners and appliances for domestic, commercial and industrial use burning:
- gaseous fuels according to EN 437; or
- liquid fuels having a viscosity at the burner inlet of 1,6 mm2/s (cSt) up to 6 mm2/s (cSt) at 20 °C, higher boiling petroleum based first raffinates (viscosity greater than 6 mm2/s), that require preheating for proper atomisation.

Zaznavala produktov zgorevanja za plinske gorilnike in plinske aparate
Standard EN 16340 določa varnostne zahteve, konstrukcijske zahteve in zahteve glede zmogljivosti za zaznavala produktov zgorevanja, namenjena uporabi v sistemih za nadzorovanje zgorevanja. Ta evropski standard se uporablja za zaznavala za merjenje produktov zgorevanja iz gorilnikov in aparatov za gospodinjsko, komercialno in industrijsko kurjenje: – plinasta goriva v skladu s standardom EN 437; ali – tekoča goriva z viskoznostjo pri dovodu gorilnika 1,6 mm2/s (cSt) do 6 mm2/s (cSt) pri 20 °C, prvi rafinati z višjim vreliščem na osnovi nafte (viskoznost večja od 6 mm2/s), ki jih je treba predhodno segreti za ustrezno atomizacijo. Ta evropski standard se uporablja za vse vrste stacionarnih zaznaval, ki merijo komponente dimnega plina O2, CO, CO2, H2, CxHy, NOX, SO2, ali za njihovo kombinacijo (več plinov).
