Differential pressure gauge

Part number: Models 716.11, 736.11

Applications

  • Differential pressure measurement at measuring points with very low differential pressures, for gaseous, dry, clean, oil and grease free media
  • Model 736.11 also for aggressive media and ambience
  • Filter monitoring in ventilation and heating systems
  • Filter monitoring in overpressure and clean rooms
  • Differential pressure controlled monitoring of ventilator and blast pressures

Special Features

  • Differential pressure measuring ranges from 0 … 2.5 mbar
  • As a standard zero adjustment in front
  • Ingress protection IP66
  • Case from stainless steel
