These rugged stainless steel transducers are ideal
for industrial, automotive, or aerospace applications
where only one side of the transducer is exposed to
wet media. These wet/dry transducers deliver the great
performance characteristics of the Micro-Machined
Silicon Series Transducers at a lower price than the
wet/wet models. They can be used in test benches, filter
monitoring, air flow, factory or pneumatic air, pitot tubes,
air speed and other industrial or aerospace applications
requiring a very rugged wet/dry transducer. The solid
state silicon core will provide long, reliable service life
with excellent long term stability.
