The Proximity Controls
Series Mark Position
Indicator/Transmitter
is a line of position indicators
with a selection of various output options. Three model
styles make up the Mark Series to cover almost any
application. A magnetic drive that completely seals the
switch compartment from the atmosphere for maximum
leak protection is utilized in the Mark 1. The Mark 3 uses
the same magnetic drive of the Mark 1, but it can be used
for multi-turn applications with 1 to 25 revolutions, such
as gate valves. A through shaft drive is incorporated in
the Mark 4 making the unit a lower cost alternative to the
Mark 1 for applications that are not as demanding.
Standard models in the Mark Series have visual position

submersible. A large variety of outputs are available to
¿WVSHFL¿FDSSOLFDWLRQV7KHUHLVDFKRLFHRIWRVZLWFK
outputs of 13 varieties including inductive sensors,
high temperature switches, gold contact switches,
hermetically sealed switches, and high current switches.
Aside from switch outputs, the Mark Series offers
potentiometer outputs, 4-20 mA transmitters, and HART
®
communication.
The units are purchased for either direct drive
applications, such as rotary valves, or lever drive
applications, such as linear valves. For the Mark 1, 3,
and 4 this instruction manual starts with installation of
the unit to the device being monitored, and the set up
of switch models. Separate instructions follow covering
the potentiometer and transmitter set up if your unit has
those options.
