General information and function

The positioning distance sensing system and controller unit can be mounted
separately in all housing variants with the SIPART PS2 positioner.
The stroke or rotary angle detection takes place directly on the drive by a
non contacting position sensor (Non Contacting Position Sensor). 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.
Such a separate installation is always useful when the ambient conditions at
the fitting exceed the specified values for the SIPART PS2 positioner.
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. The sensor housing is fixed to the console
in rotary actuators and to the NAMUR bracket in linear actuators.
The NCS is supplied with power via the EMC filter module C73451-A430-
D23 NCS and at the same time guarantees electromagnetic compatibility.
The SIPART PS2 positioner can be ordered with a pre-assembled EMC filter
module or a filter module can be retrofitted to existing controllers at any time.
