P5
The base unit of the system is the pneumatic positioner, used in either single or double acting
applications. P5 comes standard with built in dampers, a high gain spool valve assembly,
gauge ports and an O-ring sealed housing. The housing utilizes a unique O-ring seal that
can be adjusted to a sealed or drained position.
The modular design concept allows for easy addition of accessories such as I/P converter
and/or a feedback package, both which are isolated from the basic pneumatic unit. These
accessories can be factory or field mounted.
Ease of calibration and maintenance are built into to the design with easily accessible span
and zero adjustment, and very simple parts replacement.
ATEX: II 2 GD
