SVP3000: High durability and stability
Isolated design between electronics and pneumatic circuits


This design eliminates troubles caused by dusty and humid air quality.
Instrumentation air and outside atmosphere do not come into the electronics
circuit department.
Pneumatic
circuits
Even if the atmosphere is corrosive
and instrumentation air is not perfect,
it does not affect the electrical part of
the positioner.
