Standard spring-diaphragm pressure gauges for differential pressure

Description

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)

• 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
