DP-MAG
DP-MAG
The differential pressure indicator is designed for measuring pressure differences in vessels containing gaseous and liquid, non-adhesive media that are not highly viscous. It is particularly suitable for monitoring filters, pumps, pipe systems, and cooling circuits.
- Display range: 0–1 bar (other ranges up to 10 bar available)
- Max. static pressure: 100 bar
- Nominal size: 63 mm (alternative 80 mm)
- Accuracy: ±3% of full scale value
- Operating temperature: Medium and ambient Tmax = 80°C, Tmin = 0°C
- Protection class: IP 65
- Connection: Stainless steel SS316, 2 x G¼ female thread
- Measuring element: Stainless steel pressure spring
- Magnetic piston: Stainless steel SS316 / Strontium ferrite
- Seal: NBR
- Dial: Aluminium, white with green/red markings
- Housing: Aluminium, black with stainless steel SS304 front
The device operates by having pressures act on two chambers separated by a piston magnet. A pressure difference causes the piston magnet to move, which is then transmitted to a pointer via a rotary magnet, displaying the differential pressure. The mechanical separation of the pressure chamber and display ensures leak-proof operation.

Function The pressures act on two pressure chambers separated by a piston magnet. If there are different pressures in the chambers, the piston magnet is axially displaced against a pressure spring. This displacement is transmitted from the piston magnet to the pointer via a rotary magnet mounted to the pointer hub. The differential pressure is directly displayed. The complete mechanical separation of pressure chamber and display excludes the possibility of leaks. • Extremely compact and robust stainless steel measuring system • Electrical contacts can be retrofitted • IP 65 protection for pressure...
