CRISTAL 'GEM' Level Switch (top mounted 1ype) facilitates any number of pre-determined level controls initiating audio-visual signals with a single unit. It is designed to provide reliable operation in severe industrial applications. The unit consists of a vertical guide pipe (stem) within which are located the sensor switches, magnetic float sliding over the stem according to the level in the tank, switch terminal housing (head) and necessary mounting connection.

The Switch operates on the basis of the float principle with magnetic transmission (permanent magnet-reed switch).

The switch is encapsulated in the stem and it is actuated by a permanent magnet within the float.

 Salient Features
Because the switches operate on the principle of magnetic-flux coupling
   with no mechanical connections, fluid contamination of switch components
   cannot occur.
Only one moving component exists-the no wear float.
Reliable in operation because of the large gap between the slide tube of
   the float and the fixed guide tube.
Insensitive to dirt particles in the liquid.
Several levels can be monitored by several reed contacts in the guide
   tube even with one float.
Suitable for any fluid compatible with material of construction and sp.
   Gravity above 0.7.
These Switches operate in any position - from vertical to an  inclined
    angle of 45, head assembly upward or downward.
Closing, opening or change-over contacts can be selected.
Factory-set level actuation points can be easily adjusted at site.
Minimum possible actuating distance from top of connection is 30 mm.
Factory-set level actuation points can be easily adjusted at site.
Minimum possible actuating distance from top of connection is 30 mm.
Minimum possible distance between 2 level set points is 75 mm,
   if 2 independent floats are used.
All the floats and stoppers can be removed thro' bottom side  of  stem,
   if necessary, for easy installation in your vessel and  retain them to
    their original positions.

 INFORMATION REQUIRED TO QUOTE
 Materials of construction, service medium with sp. Gravity and other
 parameters of service conditions, number of actuating levels and their
 distances from top of connection and type of process connection. Also
 specify the condition of each switch required whether switch should close
