The PX2780 high accuracy
barometric pressure transducers are
designed for applications in industry
and science where accuracy, fast
dynamic response and long term
stability are important. The sensor
and electronics are packaged
in a rugged stainless steel and
polyester case. A removable 5-pin
terminal strip makes fast and secure
connections. A high accuracy
ceramic sensor is coupled with a
digital compensation circuit using a
custom ASIC to assure consistent
accuracy and reliability over a broad
range of environmental conditions.
There is also a sleep mode where
the unit only draws 1 micro amp
that allows almost instant turn on/
reading for remote applications
