MLR - Magnetic level indicator with colored rollers0 pages

magnetic level indicator model MLR
Column of colored rollers indicate the level in the tank
Badotherm magnetic level gauges are designed for gauging liquids where
glass, gaskets threaded connection etc cannot be tolerated because of
corrosion problems, toxic gases, dangerous fluids etc. Model MLR features a
column of magnetic rollers which are white on one side and red on the
other. The rollers are made from plastic with a distance of 10 mm between
the axes. As the float moves up or down the bunched field of the permanent
magnet mounted in its top section pulls the rollers through a rotation
of 180 degrees, thus changing color. As the float rises, the rollers are turned
from white to red and as the float falls, they are changed back to white
again. This model can be used with alarm switches and a transmitter with
4-20 mA output. The chamber on which the indicator is mounted must be
of a non magnetic material. The standard is AISI316 but can also be
supplied in PP, PVDF, PVC etc on request.
