Magnetic Vertical Level Switches Delta Mobrey

Description

Magnetic Vertical Level Switches by 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 and 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.

Magnetic Vertical Level Switches 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 microswitches. 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.

Mounted vertically, hermetically sealed

For extreme conditions, this vertically mounted hermetically sealed switch provides dependable control.  Specifically designed to handle corrosive atmospheres and low temperatures, the magnet switch mechanism provides a positive snap-shut action.  With fewer moving parts there is less maintenance and greater reliability.  This product is ATEX accredited.
