The OMEGA PX273 is an all
stainless steel wet/wet differential
pressure transmitter, incorporating
dual diffused piezoresistive sensing
elements with stainless steel media
isolation. The unit is compatible with
all media encountered in industrial
applications, including freon,
ammonia, treated water, and steam.
The PX273 is ideal for monitoring
and controlling pump differential
pressure, CW/HW system
differential pressure, chiller/boiler
differential pressure drop, and many
other industrial applications.
