Water treatment applications place high demands on pressure and level measuring instruments. For these applications, Baumer offers robust sensors which are suitable for high vibrations as well as for the use with aggressive media. For example, sensors made of seawater-resistant Hastelloy C and with a ceramic sensing element are available for desalination plants. Flush mount versions are offered for sewage applications. The devices can be easily configured on PC via the FlexProgrammer 9701.
Pressure and level measuring devices for water treatment applications have to be extremely robust. First of all, this concerns the materials used in instruments that are in contact with aggressive or corrosive media in applications such as desalination plants or sewage sludge processing. In addition, the devices have to be highly resistant against vibrations which are generated continuously for example in applications with volumetric pumps. Further challenges are the formation of foam, suspended solids, and condensation in tanks.
For these challenges, Baumer offers an extensive portfolio of pressure and level sensors mounted in a stainless steel – or optionally Hastelloy C or Monel – housing. They are available with a wide range of process connections and galvanically isolated output signals. They are extremely resistant against shocks and vibration and feature high temperature resistance, accuracy and long-term stability. Products ideally suitable for applications in water treatment plant include the submersible probe ED752 for hydrostatic depth measurement, the new pressure transmitters of the modularly constructed PB series, the digital pressure switch TED, the level detection device FlexLevel Switch and the ultrasonic sensors UNAR and UFAR. The measuring devices can be configured on-site in the application surrounding.
Furthermore, Baumer offers chemicals seals made of Monel or Hastelloy C in order to separate pressure switches like the TED50 from aggressive media. This solution is already used in many reverse osmosis processes used for desalting seawater. Thanks to its high vibration resistance of 1.5 mm (10..55 Hz) and 20 g (55 Hz..2 KHz) according to the EN 60068-2-6 standard, the measuring device is also used in many other water treatment processes such as ultra-filtration in urban waste water treatment plants.
