PX409 Series
Sealed Gage
Standard
The hermetically sealed gage
version of the PX409 Series
features all welded Stainless Steel
construction, 316L wetted parts and
glass to metal seals (GMS) at the
electrical outlets with either twist
lock connector (PX429) or solder
pins (PX449) terminations. This
ensures that the unit is hermetically
sealed from external environments
and the media. Designed for
use on automotive and aircraft
test platforms and anywhere
environmental concerns demand
the most durable characteristics.
The sealed gage models have the
PX409 Series micro machined
silicon core that provides high
accuracy, low drift and excellent
long term stability in the harshest
environments.
