contained in a rugged die cast aluminum housing.
FM, CSA, Atex approvals are available meeting a
wide range of classifications, divisions, and group
listings. The unit has a unique cover arrangement
that allows for simple entry into the calibration/configuration
chamber, while not exposing internal components
and thus breaking the hazardous area classification.
The D400 can be fully calibrated and even configured
from onboard push buttons or via handheld device
or network. The external visual indicator can be
adjusted for various rotations or degrees. Available
in Hart, Foundation Fieldbus, and Profibus, this
microprocessor-based positioner is available in
all key process industry communication standards.
Options such as fail in place, 4-20 mA feedback
(Hart only), microswitches, gauge block, rotary
or linear mounting are all standard options for
the D400EX unit. The unique standard option of “adaptive
control”, allows the customer to update the
complete valve package to “adapt” to
process changes, while not disturbing the Operation
mode. The very low bleed product, utilizes proven
air handling technology for dependable service,
while the microprocessor and software add accuracy
and flexibility to this positioner package. |
