Sensor Standard

OMEGA’s PX4600 Series consists of
accurate, highly reliable pressure
transducers suitable for printed circuit
board mounting. The small size and
light weight of the PX4600 tranducers
make them ideal for tough vibration
and shock environments. The sensor
is a small silicon chip with 4 diffused
silicon strain gages. Laser-trimmed
resistors provide excellent
temperature compensation from

-54 to 121ºC (-65 to 250°F), and
users can adjust zero balance

and span to tight tolerances. The
unusually high performance of this
transducer comes from a 4-active­arm bridge sensor using a micro­machined diffused silicon diaphragm
and proprietary thin-film media and
dielectric isolation barriers. See next
