The PXM409 Series use a micromachined piezoresistive silicon
element for high accuracy and all
stainless steel wetted parts for
durability and superior chemical
compatibility. Their high accuracy
combined with very high thermal
compensation (0.7% Typ.) over
the compensated range make the
PXM409 series ideal for scientific
or industrial applications requiring
a rugged, high accuracy transducer
with very low thermal drift. They
can be used in test benches,
laboratory testing, engine testing,
ground test stations and other
industrial applications requiring
PXM409-001BGV,
shown smaller
than actual size.
durable, precision transducers.
Their standard accuracy is a high
industrial grade accuracy of 0.08%.
The modular construction allows
for fast delivery of most models
(typically 2-week maximum).
Models are available with gauge
(relative), compound gauge,
absolute, vacuum (negative gauge)
and barometric pressure ranges.
