The limit value switch monitors the dynamic and/or static limit value for foam. Universally usable, allows for reliable detection, combined with easy commissioning. A reliable measurement of all products is guaranteed by applying the impedance measuring principle.

mipromex® – the limit value switch
The evaluation unit monitors, detects and controls the addition of the defoamer
The guaranteed foam detection of products with varying consistencies, electrical and dielelectrical conductivity is achieved by the dynamic three-dimensional measurement behaviour. The limit value output controls the cost-conscious use of the foam precipitating agent closes the pressure valve or interrupts the vacuum, etc.

Measuring system

The MLS tlimit value switch can be used for foam detection, fluids or powder level measuring. The first and second measurement circuits are equipped with the same functionality. The evaluation electronics not only serves as a feed unit in the 2-wire technology, it also houses the data processing intelligence.
Your benefit: High economic efficiency and investment security due to the long service life.

  • Limit value on the active measurement range length can be freely parameterised
  • Easy fault visualisation, fault notifications on 2nd relay output, if selected
  • With 1 or 2 measuring inputs
  • Limit value simulation

The standardised bar probes are configured to customer-specific process conditions and the media used. The probe technology, in contrast to the capacitive system, is also suitable for insulating, low-polarity foams.

  • Materialisation: Stainless steel, Hastelloy®, full PTFE designs
  • Contamination in the inactive area and organic residues on the measuring electrode are negligible
  • Designs for extreme process conditions with temperatures of up to max. 300°C and pressure up to 1000 bar
  • The quick measurement, 300 ms, guarantees reliable detection

Limit value probes for organic and aqueous foams

Our impedance measuring principle and the high-resolution MTI measuring electronics can record all types of foam both analogue, as a fill level tendency or digitally, as a limit value. A wide range of probes allows for all types of installation. The spatial measurement behaviour of the foam probes makes it easy to detect foams. Thanks to the product-specific probe, combined with the dynamic limit value detection, various types of foams can even be determined if the probe is contaminated. The mipromex® MLS evaluation unit is equipped with a graphic display for visualising the foam level and setting the limit value.
