PSMN"Long-term precise measurements ..."

Baumer hydrostatic sensors measure filling levels, water columns and surface levels. 
They recognize the differences in pressure, no matter what the fluid and environment, from 1 mH2O upwards.

Like the human ear they react highly sensitively to differences in pressure and pass these on to the controls as a linear scale. To do this, the pressure membrane is directly in contact with the fluid and - unlike other physical approaches to measurement of filling levels - is resistant to interference from external factors. The result is undistorted and stable measurements over the long term, even for difficult applications.

We distinguish here basically between two processes:

  • transmitters with piezoresistive silicon technology, which are primarily used in fresh water or also in the petro-chemical industry.
  • transmitters with ceramic thick film technology, which are highly resistant to aggressive fluids (chlorine, sludge), very robust and easy to clean.

 

PIEZORESISTIVE SILICON TECHNOLOGY

BENEFITS

  • very high measurement precision
  • individual parameterization, can be done locally even after installation
  • for small measuring ranges (from 1 mH2O)
  • durable thanks to the fully welded housing (no gaskets)
  • stable over long periods
  • can be used in Ex-areas (ATEX)

AREAS OF APPLICATION

  • cisterns, tanks, bodies of water, dammed lakes
  • monitoring and water supply systems
  • hydro power stations
  • pharmaceutical industry
  • shipbuilding
  • salt-water desalination plants
  • chemical/oil/gas industries
  • food and beverage processing industry

 

CERAMIC THICK FILM TECHNOLOGY

BENEFITS

  • excellent value for money
  • good resistance to fluids (chlorine, sludge etc.)
  • Plug and play (build in, measure and forget)
  • easy to clean membrane
  • robust measuring system

AREAS OF APPLICATION

  • tank storage facilities
  • sewage plants
  • swimming pools
  • pumping stations
