The dual inductive, 2-wire AC/DC Series VPS Valve Position Sensors maintain 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). 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.
BENEFITS/FEATURES
• Fully adjustable target in 2° increments
• LED indication for visual indication
• 4-pin quick disconnect electrical connection
APPLICATIONS
• The VPS is used for control element position monitoring and indication with devices
such as rotary valve actuators, rotary valves and dampers.
