OMEGA’s PX6000 pressure
transducer fits easily into your
application. This low-cost
transducer is small and light,
and mounting requires no bulky
structures.You select from
3 electrical terminations and
6 pressure fittings. The sensor is a
small [about 2.5 mm (0.1")] square
silicon chip with 4 diffused strain
gages, mounted in the stainless
steel case. Laser-trimmed resistors
provide temperature compensation
and adjust zero balance and span.
The 0 to 5 Vdc output is compatible with most control and data
acquisition systems.
The PX6000 Series uses solid
state media isolation for improved
reliability. Thin films of chemically
inert materials are deposited or
grown on the chip surface to provide
electrical isolation between the
sensor and the pressure medium.
The sensor is less sensitive to
vibration and more dependable in
high-shock environments because
the films add no significant mass.
Corrosion resistance is outstanding,
and the isolation will remain
effective because there is no
gel or oil column to deteriorate.
The PX6000 is also available in metric configurations, with G1/4 or G1/8 ports, and models
from 0-1 to 0-25 bar pressure ranges.
Please see the PXM6000 for complete details, or contact our Pressure department for more information..
