Get all the great performance characteristics of the
Micro-Machined Silicon Transducers in these wet/
wet differential pressure models. These rugged
stainless steel transducers are ideal for tough industrial
automotive, or aerospace applications requiring a wet/
wet transducer. They can be used in test benches,
filter monitoring, hydraulic, flow, or water/wastewater
applications, as well as factory or pneumatic air, pitot
tubes, air speed and other industrial or aerospace
applications. The solid state silicon core and all stainless
steel wetted parts will provide long, reliable service life
with excellent long term stability.
