Drinking water filtration system(31xx, CVV)

The sensors measure the pressure before and after the filter. With a registered drop in pressure it is time to replace the filter.

Application examples:

  Minimum operating pressure for burner-/ pump-starting

  Protection against dry running of equipment (burners / pumps)

  Function / operation condition-control for e.g. signal change at pumps starting or stopping

  Maximum pressure control of equipment

  Automatic export water supply in case of pressure decline

  Over pressure protection of solar water heating equipment

  Load/pressure-dependent controlled / regulated ( thermostat-) valves or pumps, e.g. at booster-/pressurizer-stations

  Overload protection

Product Description

Magnetic pressure sensor with analogue output signal

For liquid or gas pressure measurement

Measuring pressure 0--4,5 bar/450KPa (21xx)

Measuring pressure 0--10 bar/1MPa(31xx) 

Materials with medium contact are approved to be used in drinking water applications (31xx)


Advantages:

 Robust and simple design

 Linear measuring range

 Fully automatic 100% final test and  calibration for best accuracy

Functional Principle

Movable membrane loaded with pressure

With this travel a permanent magnet is moved relative to a Hall-IC

The Hall-IC transforms the impressed magnetic field into a proportional voltage signal

Plug on flange

Proposal for possible adaption of the water pressure sensor with plug on flange in the customer application. This adaption is used at different customers.

O-ring: 

- 9,5 x 2,5 EPDM 70 shore A

- O-ring has to be greased

Screw flange

Proposal for possible adaption for the water pressure sensor with screw flange in the customer application. This adaption is used at different customers. 

O-ring:

- 14 x 1,78 mm EPDM 70 Shore A

- O-ring has to be greased

Mounting Indication


The influence of external magnetic fields on the sensor signal may be eliminated by keeping minimum distances. Here are the dimensions for the minimum distances shown:
