SITRANS
VP300 is Siemens' newest addition to the family. It supplements our range of
positioners for use in hostile environments, and with compressed air, which is
frequently moist or contaminated.
SITRANS
VP300 is particularly easy to
operate. The graphic display can be viewed in a wide variety of languages.
Histograms and other graphic information can be output directly on the display.
The
SITRANS VP300 applies the GMR effect which was awarded a Nobel Prize in 2007.
This giant magnetoresistance discovered is used for non-contacting detection of position.
This means instead of awkwardly fitted levers and complex interaction between
the components, the SITRANS VP300 only requires a single magnet and is
immediately available for use for strokes up to 150 mm (5.9 inch) and rotary
angles up to 120.
Our
new SITRANS VP300 is equipped with the innovative OPOS interface. This multivendor
mechanical and pneumatic interface in accordance with VDI/VDE 3847 allows
simple assembly of the positioner at the front with just two screws without
external piping.
Rugged
for all applications: SITRANS VP300 is designed as standard with an aluminum
enclosure to IP66 degree of protection. The non-contacting position detection
is resistant to vibration. The valve block itself is less susceptible to
problems resulting from compressed air which is contaminated, moist or contains
oil.
By
means of a regular partial stroke test SIPART
PS2 and SITRANS VP300 ensure that ESD valves (emergency shutdown) and other
open/close automated valves remain movable in the event of an emergency.
SIPART
PS2 and SITRANS VP300 are both equipped with comprehensive diagnostics
functions as standard. In order
to provide advanced warning of expensive failures during operation, our
positioners continuously check the actuator and valve.
