OMEGA’s PX409 Series high accuracy vacuum transducers
have a uni-directional output that measures gauge vacuum, negative gauge pressure.
Ambient pressure = 0 and output increases as pressure decreases below ambient.
The transducers have all
stainless steel wetted parts and
welded construction and premium
temperature compensation which
makes them suitable for use in
tough industrial environments.
Vacuum models measure negative
gauge pressure with increasing output
for increasing negative pressure.
Ranges are from 0 to -10 inH2O to 0 to -15 psi
with uni-directional outputs of 10 mV/V,
0 to 5 Vdc and 4 to 20 mA (ambient
set at 4 mA).
