| Operation: |
The float or displacer drives a stainless
steel sheathed permanent magnet attached
to the float rod in the glandless pressure
tube. As the float rises and falls with
a changing liquid level the float assembly
moves upwards inside the pressure tube.
A switch mechanism is mounted inside
the enclosure adjacent to the pressure
tube, and is activated by the rising
or falling magnet.
The vertical movement of the float magnet
in the pressure tube simultaneously actuates
the secondary and switch magnets within
the switch mechanism, to operate the
contacts. This threemagnet system
enables the float magnet to pass the
switch and actuate switch mechanisms
at other levels. Switch mechanisms which
are actuated will not reset until the
float magnet actuates the switch mechanism
on a falling level. |

| Switch
Mechanism - Principle of Operation: |
| The switch mechanism is based on a unique Magnesonics
three-dimensional magnet design where the snap action
is accomplished by the utilization of magnetic repulsion.
The magnet mounted on the float rod causes the secondary
magnet to rotate as it passes up and down. The switch
magnet is repelled by the secondary and snaps to
the opposite side. This causes the cradle to pivot,
moving the push rods which operate the switch contacts.
The result is positive snap action interlock switching
... no springs ... no spring problems. |

| The Float Chamber: |
The flanged chamber construction
of this X series range of vertical controls makes
them a very serviceable level control solution
for petrochemical, power generation and OEM applications.
The unique three-magnet memory latching system
provides reliable switching for applications such
as level alarm, safety shutdown and pump control
in product storage tanks, gas scrubbers, process
vessels, and high pressure steam generators.
Single or multi-switch models are available. Chambers
are designed to ANSI 1331.1 Power Piping Code and
ANSI 1331.3 |
