Spring-diaphragm pressure gauges for chemical applications MF100ChDif | 88086402
Spring-diaphragm pressure gauges for chemical applications for differential pressure - overload protected
manufactured goods
- direct indication of the differential pressure
- high overload protection
- compact design
- high resistance to chemicals
- Electrical contacts optional
For differential pressure measurement at low differential pressure and high static pressure. For corrosive gaseous and liquid media which are not highly viscous, also for use in corrosive environments. Particularly suitable for monitoring filters, pumps and pipe systems.
- Type
- MF ChDif D402
- 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)
