OMEGA’s PX2760 Series
barometric pressure transducers
use a capacitive sensor that has
excellent thermal stability and low
hysteresis. The signal is processed
through a custom ASIC, ensuring
long-term reliability and accuracy.
The amplified 0.1 to 5.1 Vdc output
makes these transducers compatible
with most process controllers and
computer interface equipment and is
virtually immune to EMI and RFI.
