Magnetic Level Indicators


Magnetic level indicators combine up to three functions in a single unit: display, switch and transmitter. The display, which can be read from great distances, works without energy and, due to the physical law of liquids in communicating vessels, in a forced manner.

A separate permanent magnet is integrated into each leaf of the display. The display leaves are thereby magnetically coupled and stabilised in their position. Together with the dampening field of the magnetic guide tape, a clear level display is guaranteed, even under difficult operating conditions (for example, level change, vibrations).

Standard materials are 316/316L 1.4435/1.4404, austenitic stainless steel of the Group A4. Other steels, alloys and plastics offer a high flexibility in the choice of materials.

Operational pressures from vacuum to 500 bar, liquid densities > 0.3 g/cm³ as well as a temperature range from 77K to 673K (-196°C to 400°C) allow use in applications for cryogenic liquefied gases, as well as in water hydraulics and in steam boilers. Closed floats for condensing media up to a max. operating pressure of 320 bar are also available.

Side and in-line connection versions with the designations A, B, K and O are available in all series except the Economy series. Mixed versions for these tank connections can also be realised.
