Magnetic Vertikal Level Switches Delta Mobrey


For critical area applications or general purpose control you need to trust that your level switches won’t let you down. Mobrey float and Displacer level switches are rugged, robust, and trusted globally for their long-term reliability in the harshest of environments and the most hazardous areas.

These level switches can be optionally supplied mounted vertically in chambers, in a sealed or removable form. A range of carbon steel chambers are available, and for more vigorous applications there are stainless steel chambers. There are a variety of instrument and process connection options available to make installation simple and economic.

Quality and reliability

Mobrey vertical magnetic level switches for industrial and process control use have been available for over 20 years and have gained a reputation for quality and reliability. Choice of switching mechanisms There are two switching functions available: 2 x SPST (SPCO) or DPDT (DPCO) switching, and each comes in four variants:

  • General purpose with silver cadmium oxide contacts for long life
  • Low power circuit with gold-plated contacts for use in low current and voltage applications such as Intrinsically Safe (IS) circuits
  • High power circuits giving up to 10 Amps switching capability
  • Hermetically-sealed for the ultimate in reliability – sealed for life

Based on the industry-standard boiler water level controls, these controls use the same three-magnet switch mechanism for snap-action latching and switching. The design of this unique switch mechanism overcomes all the inherent problems of mercury tubes and micro switches. Even under severe vibration conditions, there are no springs to cause contact bounce, hover, or even failure. The snap-action magnets give a positive and stable latching, time after time after time.


  • Unique switching mechanism – totally reliable
  • No springs in switch mechanism – positive snap action switching
  • Vibration resistant – eliminates spurious trips
  • Multiple switch point options – cost effective control
  • Genuine hermetically-sealed switch option – totally safe and secure
  • Extensive range of chambers – suitable for most applications
  • Relevant chambers are supplied CE marked and fully compliant with the Pressure Equipment Directivem (97/23/EC)
  • Designed to ASME B31.3
