OMEGA’s PX409 Series high accuracy vacuum transducers have a uni-directional output that measures gage vacuum, negative gage 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 gage 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).
