FEMA DWAM/DWAMV | Steam and Hot-Water Pressure Monitors | PED 2014/68/EU, burst >= 100 bar, SIL 2
FEMA DWAM and DWAMV pressure monitors handle maximum-pressure monitoring in steam and hot-water systems to TRBS, DIN EN 12828, DIN EN 12952-11 and DIN EN 12953-9. The special-construction switch has a self-monitoring pressure sensor built to the Pressure Equipment Directive 2014/68/EU, with a TÜV-verified bursting pressure of at least 100 bar. DWAM types have no differential adjustment; DWAMV types do.
Key features
- Self-monitoring sensor of special construction
- Calibrated so switching occurs at the set point under rising pressure
- Usable as pressure monitor or maximum-pressure limiter
- Rugged housing of seawater-resistant die-cast aluminium
- TÜV-DW-15-132 approval and SIL 2 to IEC 61508-2
