Standard spring-diaphragm pressure gauges for differential pressure


Description

Standard spring-diaphragm pressure gauges for differential pressure – overload protected

MF 100 Dif D401
Manómetros estándar de diafragma para presión diferencial

Features:

Direct indication of the differential pressure
High overload protection
Zero correction
With integrated pressure damping

 

Application:

For differential pressure measurement at low differential pressure and high static pressure. For non-corrosive gaseous and liquid media which are not highly viscous. Particularly suitable for monitoring
filters, pumps and pipe systems.

 

Technical specifications:

  • Type
    • MF 100 Dif D401
  • Nominal size
    • 100
  • Function
    • The pressures act on two pressure chambers
      separated by an elastic diaphragm. If there are
      different pressures in the chambers, the diaphragm
      is axially displaced against a compression
      spring. This is transmitted to the movement by
      means of a rod. The differential pressure is directly
      indicated by a pointer. The diaphragm is held by
      a metallic support which results in an overpressure
      safety of up to 25 bar at both sides.
  • Accuracy class (EN 837-3/6)
    • 2.5
  • Ranges (EN 837-3/5)
    • 0/250 mbar to 0/6 bar
  • Maximum static pressure
    • 25 bar
  • Overpressure safety
    • Up to 25 bar at both sides
  • Operating temperature range
    • Medium: Tmax = +60 °C
    • Ambient: Tmin = -20 °C
    • Tmax = +60 °C
  • Temperature performance
    • Indication error when the temperature of the
      measuring system deviates from the normal
      temperature of 20 °C:
      rising temperature approx. ±0.5 %/10 K
      falling temperature approx. ±0.5 %/10 K
      of full scale value
  • Degree of protection
    • IP 54 (EN 60529)
