Series VPS Valve Position Sensor
Specications - Installation and Operating Instructions
Bulletin F-65
The dual inductive, 2-wire AC/DC Series VPS Valve Position Sensor maintains VDI/
VDE 3845 dimensions so positioners can be easily mounted on top of the sensor and
target. The Model VPS2411 Sensor and Model P1 Target mount easily and directly to
actuators with ISO-NAMUR topworks (see picture below). Fully adjustable target in
2° increments, the sensor has two independent LED’s and bright Flow Line indicator
that provide local visual indication. All electrical connections are made with the Model
VIP82 4-pin quick disconnect cable (6 ft. in length) for ease in installation. Solid state
components are fully embedded in an epoxy resin to prevent condensation build-
up and to protect against vibration and shock. The rugged PBTP housing provides
excellent corrosion resistance and moisture protection.
Two VPS2411 and one P1 shown mounted with W.E. Anderson pneumatic actuator
and positioner.

INSTALLATION DRAWING
INSTALLATION PROCEDURE:
1. Fasten the Series VPS to the actuator with the appropriate fasteners (M5, 10-
24, 10-32). For Namur C actuators you must rst attach the Namur C bracket to the
actuator.
2. Attach the coupling to the actuator shaft for Namur A &C actuators only.
3. Attach the collar to the actuator shaft or coupling.
4. Install one stainless steel at head screw (two if it is a dual sensor installation) into
each of the target rings and plug the other holes with the plastic screws or plugs.
Slide the target rings over the collar and adjust as appropriate for open and closed
position. Note: Bottom target energizes the red LED and the top target energizes
the green LED.
5. Place the cover onto the top target being careful to align for proper ow indication
and secure with M6 x 16 fastener for Namur B actuators or M6 x 25 fastener for
Namur A & C actuators.
6. Insert ow indicator to complete assembly or install coupling to maintain VDI/VDE
3845 dimensions if accessories such as a positioner are to be installed.
