Harsh Environments

OMEGA’s PX51 Series consists of
high-accuracy, low-cost pressure
transmitters. Their sealed, all
stainless steel construction makes
them suitable for the harshest
environments. They are available
in gage, absolute, or sealed gage
models. Ten feet of PVC insulated
shielded cable is standard, or
a twist-lock style connector is
also available. A wide selection
of amplified voltage and current
outputs makes the PX51 a truly
versatile family of industrial
transmitters.
