Operating Instructions
DESCRIPTION
General – The Non Contacting Position Sensor (NCS) is a sensor to detect valve and flap positions for
the electropneumatic positioner SIPART PS2. The positioning distance sensing system and controller
unit can be mounted separately in all housing variants with the SIPART PS2 position controller
The controller unit can then be mounted at some distance on a mounting tube or similar and is
connected to the positioning distance sensing system by an electric cable and with the drive by one or
two pneumatic lines.
The NCS consists of cast sensor to be mounted permanently and a magnet. The magnet is mounted
directly on the spindle in linear actuators or on the shaft stump in rotary actuators
