Pneumatikksymboler

Pneumatikksymbolene er i henhold til standarden ISO 1219-1 som gjør at informasjon kan utveksles uavhengig av språk. Symbolene er bygget opp slik at de etter behov skal inneholde informasjon om følgende:

• Funksjon

• Aktiverings-/betjeningsmåter

• Antall tilkoblinger

• Antall sjaltestillinger

• Generelle funksjonsbeskrivelser

• Forenklet beskrivelse av strømningsretninger
