Description
Standard spring-diaphragm pressure gauges for differential pressure – overload protected
MF 100 Dif D401
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.
- The pressures act on two pressure chambers
