Add to quote list
Description

Measurement applications

  • Level measurement of liquids in storage tanks, containers, oil sumps and tanks
  • Water and wastewater treatment
  • Mechanical and plant engineering
  • Shipbuilding
  • Energy technology
  • Diesel tanks
  • Possible to made for customer specific purposes

Short description
Level measurement is carried out according to the Archimedes’ principle for liquids in a semi continuous manner. The float moves along the guide tube as the level rises or falls. With its magnetic field, the magnet in the float actuates the reed chain that is installed in the guide tube. As a result, a resistance value is converted into a standard signal 4 to 20 mA and transmitted. The signal can be evaluated and processed further by downstream electronic components. The output signal always refers to a level change.
In the case of applications with large filling heights, level switches up to 4 m in length are available.
Depending on the variant ordered, various electrical connections, process connections, guide tube lengths, floats, and resolutions are available.

Optional temperature sensor
With the optional temperature sensor or temperature switch, the temperature can also be recorded via just one measuring point in addition to the level measurement.

Explosion-proof
The JUMO Nesos R20 LT can also be delivered according to EX i (intrinsic safety) or EX d (flameproof enclosure) standards in connection with explosion-proof environments. With an Ex d version, no Zener barrier or insulator is required in the control cabinet.

Customer benefits

  • Cost-effective installation and mounting due to the fact that, among other things, no programming or configuration is required.
  • Reduced operating costs due to maintenance-free device design
  • No supply isolator required for Ex d (Flameproof enclosure) applications
  • In the event of an optional temperature switch, no isolating switch amplifier is required for
    Ex d (Flameproof enclosure) applications
  • Customer-specific linearization for tank volume calculation possible upon request
