GENERAL DESCRIPTION:
Paddle type flow switches can be used wherever a
simple economic yet reliable monitoring instrument is required for
flow switching applications.
The device operates as follows: The flowing medium presses
against the paddle of flow switch. The paddle is
fitted to one end of a balance arm which is in direct contact with
a pre-stressed leaf spring. At the other end of the balance arm is
a permanent magnet. This magnet actuates a reed contact
located within a moveable housing outside the media.
The reed contact switches on or off depending on the position of
the permanent magnet and the switch housing. The status of the
switch may then be used to electrically control the fluid flow. The
movable reed switch on the Kobold PSR/PS allows the contacts
to be set either normally open (N/O) or normally closed (N/C).
