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

¿WVSHFL¿FDSSOLFDWLRQV7KHUHLVDFKRLFHRIWRVZLWFK

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.
