Series 7S / 9S Pressure Transducers
|
The Series 7S / 9S is the latest development in media isolated
piezoresistive silicon chip pressure transducers.
The new low mass one-piece housing is smaller with a brazed
stainless steel diaphragm for lower production cost, giving
excellent long-term stability combined with easy installation.
The Series 7S / 9S can be installed into a housing using an
0-ring seal, or it can be welded. Welding should only be made
to the flange at the rear of the transducer.
Performance specifications will remain unaffected by the installation
or welding process. The 0-ring seal may be fitted directly
below the flange, or as a peripheral seal at the front face
of the transducer. The rear flange can be modified or machined
off completely where space is important. The thin flange and
outer capsule wall ensure that mechanical mounting stresses
are not transmitted into the measuring cell. The structure
also has good thermal conductance and the sensor closely tracks
the process media temperature.
The transducer is constructed from 316L stainless steel, using
a high temperature hydrogen brazing technique, the brazed
316L diaphragms are highly resistant to corrosion. Electrical
connection is made via a five-pin header. Leadout wires, or
a PCB. can be soldered directly to the header pins. Series
7SE / 9SE versions are supplied with PCB fitted.
Typical applications are, heating pumps, autoclaves and dialysers.
Other applications include measurement of altitude, avionics,
meteorology, servo controls, robotics, hydraulics, hygienic
and pharmaceutical engineering, drift mining, injectors, and
many more.
