Media Compatibility:
AI: Absolute pressure sensors for use with gases and liquids
compatible with 316L SS
Pressure Limits:
AI units: 77 PSIA (4000 mm Hg Abs)
Connection:
1/8” female NPT, 316L SS. P1 is the pressure connection.
P2 is not accessible (factory plugged with metal disc)
User must use a wrench on the pressure manifold when
installing user’s 1/8” NPT fitting. Do not tighten the
fitting without using a wrench on the pressure
manifold. Failure to use a wrench on the manifold will
damage the plastic enclosure and void warranty No
torque should be applied to the manifold with respect
to plastic enclosure.
