Safety Applications as per the Pressure and Gas Appliance Directives

The safety of installations for the generation of steam, burnable gases and liquids is ensured by means of various forms of instrumentation. The monitoring of fuel supply and the pressure monitoring of the steam generator must be performed using devices certified according to the Pressure Equipment Directive or the Gas Appliance Directive.

Pressure monitors and pressure limiters for steam boiler conforming to TRD 604 and for hot water constructions according to DIN EN 12828 are safety-relevant components and are thus classified in category 4 of the Pressure Equipment Directive. FEMA pressure monitors and limiters are certified according to Vd-TÜV Druck100/4 and DIN EN 12952-11 and DIN EN 12953-9.
