TECHNOLOGY
A permanent magnet
is attached to a pivoted
switch actuator and adjustment screw
. As the
float
rises following the liquid level, it raises the
attraction sleeve
into the field of the magnet,
which then snaps against the non-magnetic
enclosing tube
, actuating the switch
. The
enclosing tube provides a static pressure boundary
between the switch mechanism and the process.
On a falling level, an inconel spring retracts the
magnet, deactivating the switch.

The right- and left-hand mounting arrangement refers to
the position of the try cock tappings in relation to the
gauge glass connections.
To determine whether the control mounting is right- or
left-hand, position the control with the gauge glass con-
nections facing you. If the try cock tappings are to the
right, it is a right-hand control, if they are to the left, it is
a left-hand control. Refer to illustrations below.
