Pressure monitor FD

Pressure monitor

Flexible and highly robust pressure monitor for safe and reliable monitoring of pressure limits.

Functionality: Mechanical spring-loaded membrane switching system

  • Excess pressure monitor for gases and excess or reduced pressure monitor for air
  • Suitable for all gases in accordance with DVGW worksheet G 260 and for air
  • Available for increased application requirements in accordance with DIN EN 1854 class “S”
  • Increased media resistance through the use of membranes made of fluorocarbon rubber, materials free of non-ferrous metals
  • Robust die-cast aluminum housing, optionally with housing coating
  • Continuously variable switching pressure adjustment
  • Variable electrical connection variants
  • Local indication when switching pressure is reached
  • Approvals: DVGW, EAC
  • Fastening clips integrated in the pressure monitor
  • Safe and reliable monitoring of pressure limits
  • Reliable and long-lasting operation due to high-quality components 
  • Use in harsh and difficult environments
  • Flexible use thanks to extensive equipment options
  • Straightforward installation and commissioning
  • Combustion technology
  • Ventilation technology
  • Air conditioning
  • Coating systems
  • Technical data
