Standard spring-diaphragm pressure gauges MF100Dif | 88087401
Standard spring-diaphragm pressure gauges for differential pressure - overload protected
manufactured goods
- direct indication of the differential pressure
- high overload protection
- Zero correction
- with integrated pressure damping
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.
- Type
- MF100Dif D401
- Nominal size
- 100 - 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
- see ordering table
- maximum static pressure
- 25 bar
- Overpressure safety
- up to the maximum static pressure at both ends
- Operating temperature range
- Medium:
- max. 60 °C
- Ambient:
- -20/+60 °C
- Temperature performance
- Indication error when the temperature of the measuring system deviates from the normal temperature of 20 °C:
bei Temperaturzunahme ca. ± 0,5 %/10 K,
falling temperature approx. ± 0.5 %/10 K
