The PX139 Series pressure
transducer uses state-of-the-art
micro-machined silicon sensors
with stress-free packaging
techniques to provide highly
accurate, temperature-compensated
pressure measurements for the
most demanding applications.
Designed to operate from a 5 Vdc
power source, the PX139 provides
a calibrated 4V output span of
0.25 to 4.25V.
